Lysozyme sorption in hydrogel contact lenses. (1/453)

PURPOSE: To examine the processes involved in formation of protein deposits on hydrogel contact lenses. METHODS: The adsorption and/or penetration of lysozyme on or into three types of contact lenses, etafilcon A, vifilcon A, and tefilcon, were investigated in vitro using a radiolabel-tracer technique, x-ray photoelectron spectroscopy, and laser scanning confocal microscopy. RESULTS: Binding of lysozyme to high-water-content, ionic contact lenses (etafilcon A and vifilcon A) was dominated by a penetration process. The extent of this penetration was a function of charge density of the lenses, so that there was a higher degree of penetration of lysozyme in etafilcon A than in vifilcon A lenses. In contrast, the binding of lysozyme to tefilcon lenses was a surface adsorption process. The adsorption and desorption kinetics showed similar trends to those found in human serum albumin (HSA) adsorption on lens surfaces. However, the extent of lysozyme adsorption on tefilcon is much higher than HSA adsorption, probably because of the self-association of lysozyme on the tefilcon lens surface. Furthermore, either penetration or adsorption of lysozyme involved reversible and irreversible processes and were both time dependent. CONCLUSIONS: Binding of lysozyme to hydrogel lenses involves surface adsorption or matrix penetration. These processes may be reversible or irreversible. The properties of the lens materials, such as charge density (ionicity) and porosity (water content) of the lenses, determine the type and rates of these processes.  (+info)

Sympathetic swelling response of the control eye to soft lenses in the other eye. (2/453)

PURPOSE: To compare central corneal swelling and light scatter after 8 hours of sleep in eyes wearing high- and low-Dk hydrogel lenses and to the contralateral control eyes. METHODS: Twenty neophyte subjects wore a Lotrafilcon A (Dk, 140; Ciba Vision, Duluth GA) silicone hydrogel lens and an Etafilcon A (Dk, 18; Acuvue; Vistakon, Jacksonville, FL) 58% water content hydrogel lens of similar center thickness in random order in the right eye only, for overnight 8-hour periods. The contralateral nonwearing left eyes served as controls. Central corneal thickness was measured using an optical pachometer and light scatter using a Van den Berg stray-light meter before lens insertion, after lens removal on waking, and every 20 minutes for the next 3 hours. RESULTS: Central corneal swelling induced by the Etafilcon A lens on eye opening was significantly higher than with the Lotrafilcon A lens (8.66%+/-2.84% versus 2.71%+/-1.91%; P<0.00001). Light scatter induced by the Etafilcon A lens on eye opening was significantly higher than with the Lotrafilcon A lens (46.09+/-5.62 versus 42.78+/-6.07 Van den Berg units, P = 0.0078). The swelling of the control eyes paired with the Etafilcon A lens-wearing eyes was also slightly but significantly higher than that of the control eyes paired with the Lotrafilcon A lens-wearing eyes (2.34%+/-1.26% versus 1.44%+/-0.91%; P = 0.0002). Light-scatter measurements were not significantly different between control sets of eyes but showed the same trend. CONCLUSIONS: In neophyte subjects, corneal swelling of the contralateral control eyes appears to be influenced by the swelling of the fellow lens-wearing eyes-that is, the swelling of the contralateral control eye was significantly lower when there was less swelling of the fellow eye wearing the high-Dk lens. Although there was no statistically significant difference in light-scatter measurements between the control sets of eyes, a trend similar to the corneal swelling results was observed, which could be used to support the suggestion that this may be a sympathetic physiological response rather than an unusual sampling coincidence.  (+info)

Orally administered, insulin-loaded amidated pectin hydrogel beads sustain plasma concentrations of insulin in streptozotocin-diabetic rats. (3/453)

We report successful oral administration of insulin entrapped in amidated pectin hydrogel beads in streptozotocin (STZ)-diabetic rats, with a concomitant reduction in plasma glucose concentration. The pectin-insulin (PI) beads were prepared by the gelation of humilin-pectin solutions in the presence of calcium. Separate groups of STZ-diabetic rats were orally administered two PI beads (30 micrograms insulin) once or twice daily or three beads (46 micrograms) once daily for 2 weeks. Control non-diabetic and STZ-diabetic rats were orally administered pectin hydrogel drug-free beads. By comparison with control non-diabetic rats, untreated STZ-diabetic rats exhibited significantly low plasma insulin concentration (0.32+/-0. 03 ng/ml, n=6, compared with 2.60+/-0.44 ng/ml in controls, n=6) and increased plasma glucose concentrations (25.84+/-1.44 mmol/l compared with 10.72+/- 0.52 mmol/l in controls). Administration of two PI beads twice daily (60 micrograms active insulin) or three beads (46 micrograms) once a day to STZ-diabetic rats increased plasma insulin concentrations (0.89+/-0.09 ng/ml and 1.85+/- 0.26 ng/ml, respectively), with a concomitant reduction in plasma glucose concentration (15.45+/-1.63 mmol/l and 10.56+/-0.26 mmol/l, respectively). However, a single dose of PI beads (30 micrograms) did not affect plasma insulin concentrations, although plasma glucose concentrations (17.82+/-2.98 mmol/l) were significantly reduced compared with those in untreated STZ-diabetic rats. Pharmacokinetic parameters in STZ-diabetic rats show that the orally administered PI beads (30 micrograms insulin) were more effective in sustaining plasma insulin concentrations than was s.c. insulin (30 micrograms). The data from this study suggest that this insulin-loaded amidated pectin hydrogel bead formulation not only produces sustained release of insulin, but may also reduce plasma glucose concentration in diabetes mellitus.  (+info)

Biomechanical and histological evaluation of hydrogel implants in articular cartilage. (4/453)

We evaluated the mechanical behavior of the repaired surfaces of defective articular cartilage in the intercondylar region of the rat femur after a hydrogel graft implant. The results were compared to those for the adjacent normal articular cartilage and for control surfaces where the defects remained empty. Hydrogel synthesized by blending poly(2-hydroxyethyl methacrylate) and poly(methyl methacrylate-co-acrylic acid) was implanted in male Wistar rats. The animals were divided into five groups with postoperative follow-up periods of 3, 5, 8, 12 and 16 weeks. Indentation tests were performed on the neoformed surfaces in the knee joint (with or without a hydrogel implant) and on adjacent articular cartilage in order to assess the mechanical properties of the newly formed surface. Kruskal-Wallis analysis indicated that the mechanical behavior of the neoformed surfaces was significantly different from that of normal cartilage. Histological analysis of the repaired defects showed that the hydrogel implant filled the defect with no signs of inflammation as it was well anchored to the surrounding tissues, resulting in a newly formed articular surface. In the case of empty control defects, osseous tissue grew inside the defects and fibrous tissue formed on the articular surface of the defects. The repaired surface of the hydrogel implant was more compliant than normal articular cartilage throughout the 16 weeks following the operation, whereas the fibrous tissue that formed postoperatively over the empty defect was stiffer than normal articular cartilage after 5 weeks. This stiffness started to decrease 16 weeks after the operation, probably due to tissue degeneration. Thus, from the biomechanical and histological point of view, the hydrogel implant improved the articular surface repair.  (+info)

Evaluation of properties microcrystalline chitosan as a drug carrier. Part 1. In vitro release of diclofenac from mictocrystalline chitosan hydrogel. (5/453)

The influence of microcrystalline chitosan hydrogel, alone (MCCh) as well as in combination with methylcellulose (MC) or Carbopol (CP), on the release of diclofenac free acid (DA) and its salt (DS) was studied in vitro. Commercial Olfen gel (Mepha Ltd., Switzerland) was applied as a reference preparation. The influence of hydrophilizing agents (1,2-propylene glycol and glycerol) and methycellulose hydrogel on the rheological properties of the vehicle and on the release of drug from modified MCCh hydrogel was studied. The quantity of the released substance was determined by UV-spectroscopy. The results confirmed that release was dependent on the chemical character of the drug and on the type of vehicle. The process of diclofenac release from MCCh hydrogels as well as from Carbopol hydrogels runs in two phases. The first phase is characterised by rapid release whereas in the second phase the release is much slower. The most suitable basis for diclofenac is microcrystalline chitosan hydrogel with addition glycerol, 1,2-propylene glycol, and methylcellulose hydrogel.  (+info)

Improvement of transdermal permeation of captopril by iontophoresis. (6/453)

AIM: The feasibility of iontophoresis on the transdermal delivery of captopril was studied. METHODS: Iontophoresis was employed for enhancing transdermal transport of captopril through rat skin in vitro and in vivo. RESULTS: It was demonstrated that the iontophoresis-induced flux of captopril was affected by various factors such as pH, ionic concentration, and the concentration of captopril in donor compartments as well as the applied electric current intensity. Electric current could induce several-fold increase in captopril flux with hydrogel. Skin permeation study in vivo in rats demonstrated that iontophoresis could effectively promote the transdermal transport of captopril without significant skin irritation. Captopril concentration in plasma reached plateau (approximately 0.9 microgram/mL) at 1 h after current application and was maintained at the same level during the experiment. On the contrary, captopril could not be detected in plasma when the current was not applied. No obvious skin irritation was observed after 9-h continuous iontophoresis. CONCLUSION: Transdermal delivery of captopril can be effectively improved by iontopophoresis.  (+info)

Imaging of hydrogel episcleral buckle fragmentation as a late complication after retinal reattachment surgery. (7/453)

Hydrogel encircling bands were introduced in the early 1980s as a product that was superior to bands composed of silicone rubber or silicone sponge for the surgical treatment of retinal detachment. Late complications consisting of orbital swelling and diplopia requiring band removal began to be reported in the early 1990s. Pathologic studies of these expanded fragments of hydrogel material after removal showed in vivo hydrolysis with foreign body reaction and dystrophic calcification. We report the imaging findings in five patients in whom this late complication developed. Hydrogel fragmentation has a characteristic imaging appearance consisting of a circumferential orbital mass associated with rim enhancement. This appearance should prompt inquiries regarding previous scleral buckle procedures with hydrogel bands. Familiarity with this appearance will avoid misinterpretation and unwarranted biopsy before band removal.  (+info)

Cell traction forces on soft biomaterials. I. Microrheology of type I collagen gels. (8/453)

A laser-trap microrheometry technique was used to determine the local shear moduli of Type I collagen gels. Embedded 2.1 microm polystyrene latex particles were displaced 10-100 nm using a near-infrared laser trap with a trap constant of 0.0001 N/m. The trap was oscillated transversely +/- 200 nm using a refractive glass plate mounted on a galvanometric scanner. The displacement of the microspheres was in phase with the movement of the laser trap at frequencies less than 1 rad/s, indicating that at least locally, the gels behaved as elastic media. The local shear modulus was measured at various positions throughout the gel, and, for gels at 2.3 mg/mL and 37 degrees C, values ranged from G = 3 to 80 Pa. The average shear modulus G = 55 Pa, which compares well with measurements from parallel plate rheometry.  (+info)

DSpace@MIT: In vitro culture of a chondrocyte-seeded peptide hydrogel and the effects of dynamic compression[email protected]: In vitro culture of a chondrocyte-seeded peptide hydrogel and the effects of dynamic compression
Emerging medical technologies for effective and lasting repair of articular cartilage include delivery of cells or cell-seeded scaffolds to a defect site to initiate de novo tissue regeneration. Biocompatible scaffolds assist in providing a template for cell distribution and extracellular matrix accumulation in a three-dimensional geometry. In these studies, a self-assembling peptide hydrogel is evaluated as a potential scaffold for cartilage repair using a model bovine cell source. A seeding technique is developed for 3-D encapsulation of chondrocytes in a peptide hydrogel. The chondrocyte-seeded peptide hydrogel was then evaluated cellular activities in vitro under standard culture conditions and also when subjected to dynamic compression. During 4 weeks of culture in vitro, chondrocytes seeded within the peptide hydrogel retained their morphology and developed a cartilage-like ECM rich in proteoglycans and type II collagen, indicative of a stable chondrocyte phenotype. Time dependent ...

Hydrogel particles, also known as microgels, consist of cross-linked three-dimensional water-soluble polymer networks. They play an essential role in loading and delivering active ingredients in medicine, cosmetics, and foods. Despite their excellent biocompatibility as well as structural diversity, much wider applications are limited due mainly to their intrinsically loose network nature. This study introduces a practical and straightforward method that enables fabrication of hydrogel microparticles layered with a mechanically robust hybrid thin shell. Basically highly monodisperse hydrogel microparticles were produced in microcapillary devices. Then, their surface was coated with alternate polyelectrolyte layers through the layer-by-layer deposition. Finally a thin silica layer was again formed by reduction of silicate on the amino-functionalized polyelectrolyte layer. We have figured out that these hybrid hydrogel microparticles showed controlled loading and releasing behaviors for ...

The combination of hydrogel and nitrogen may favor the expression of grain productivity of wheat. The goal of the study was to analyze the nitrogen utilization efficiency in wheat through the hydrogel biopolymer, defining the optimal dose of hydrogel and nitrogen combination at the maximum grain productivity, in succession systems of high and reduced N-residual release. The study was carried out in 2014 and 2015, in randomized block design with four replicates in a 4 x 4 factorial, for hydrogel doses (0, 30, 60 and 120 kg ha-1), added in the furrow along the seed and fertilizer-N doses (0, 30, 60 and 120 kg ha-1), applied in the stage of third leaf expanded, respectively, in the soy/wheat and corn/wheat systems. The hydrogel biopolymer increases the efficiency of nitrogen use in grain productivity of wheat in succession systems. The ideal combination of hydrogel and nitrogen at the maximum grain productivity is 58 and 93 kg ha-1, respectively, in the soybean/wheat systems and 44 and 115 kg ha-1, ...

Congratulations to Jiwei Cui et al from the University of Melbourne and the Laboratory for Mechanics of Materials and Nanostructureswho recently published Super soft hydrogel particles with tunable elasticity in a microfluidic blood capillary model in Advanced Materials. The paper explores super-soft PEG hydrogel particles with tunable elasticity which are prepared via a mesoporous silica templating method. The deformability behavior of these particles, in a microfluidic blood capillary model, can be tailored to be similar to that of human red blood cells.

Scientists use the Chimeric Hydrogel for Targeting the Tumor Progression - Regional Centre for Biotechnology BlogScientists use the Chimeric Hydrogel for Targeting the Tumor Progression - Regional Centre for Biotechnology Blog
Group led by Dr. Avinash Bajaj from Regional Centre for Biotechnology designed a low molecular weight hydrogel that can maintain sustained and sequential release of combination of drugs and inhibit the tumor progression in murine models. Using the bioconjugation strategies and biocompatible bile acid and peptide scaffolds, Dr. Bajajs group engineered a biocompatible and biodegradable hydrogel. They then entrapped a combination of anti-proliferative (doxorubicin), anti-angiogenic (combretastatin) and anti-inflammatory (dexamethasone) drugs in the hydrogel. Local implantation of the hydrogel reduces the tumor growth kinetics significantly and enhances the median survival. In collaboration with Dr. Ujjaini Dasgupta group at Amity University, Haryana, they have deciphered the in-depth mechanism and found that hydrogel-mediated delivery of combination of drugs alters the sphingolipid metabolism and helps in combating drug resistance..

Bioinspired hydrogel surfaces to augment corneal endothelial cell monolayer formation | AVESÄ°SBioinspired hydrogel surfaces to augment corneal endothelial cell monolayer formation | AVESÄ°S
Corneal endothelial cells (CECs) have limited proliferation ability leading to corneal endothelium (CE) dysfunction and eventually vision loss when cell number decreases below a critical level. Although transplantation is the main treatment method, donor shortage problem is a major bottleneck. The transplantation of in vitro developed endothelial cells with desirable density is a promising idea. Designing cell substrates that mimic the native CE microenvironment is a substantial step to achieve this goal. In the presented study, we prepared polyacrylamide (PA) cell substrates that have a microfabricated topography inspired by the dimensions of CECs. Hydrogel surfaces were prepared via two different designs with small and large patterns. Small patterned hydrogels have physiologically relevant hexagon densities (similar to 2000 hexagons/mm(2)), whereas large patterned hydrogels have sparsely populated hexagons (similar to 400 hexagons/mm(2)). These substrates have similar elastic modulus of native ...

Hydrogel Implant Could Make Booster Shots ObsoleteHydrogel Implant Could Make Booster Shots Obsolete
Weve all had booster shots at some point in our lives. You know, you get an immunization injection, then at some point in the future you have to have another round to make sure you have the proper level of immunity.. This can be a major pain (pardon the pun) for many of us. When I received my Hepatitis B vaccine while in dental school, the proper protocol was for a 3 shot series.. Now, in dental school, it was easy. The injections were given by the oral surgery department and I was notified when to return for my next round. However, in the real world this can mean more trips to a doctors office for these follow up visits. This can result in lost work time, taking kids out of school, etc. Not to mention the fact that you actually have to get the injections to ensure immunity. Lots of people either forget or are scared and just dont get them.. Now comes word of a way around these booster injections.. The idea is to place a booster amount in a small pea sized hydrogel capsule that is injected ...

Moldable Hyaluronan Hydrogel Enabled by Dynamic Metal-Bisphosphonate Coordination Chemistry for Wound HealingMoldable Hyaluronan Hydrogel Enabled by Dynamic Metal-Bisphosphonate Coordination Chemistry for Wound Healing
Biomaterial-based regenerative approaches would allow for cost-effective off-the-shelf solution for the treatment of wounds. Hyaluronan (HA)-based hydrogel is one attractive biomaterial candidate because it is involved in natural healing processes, including inļ¬‚ammation, granulation, and reepi-thelialization. Herein, dynamic metal-ligand coordination bonds are used to fabricate moldable supramolecular HA hydrogels with self-healing properties. To achieve reversible crosslinking of HA chains, the biopolymer is modiļ¬ed with pendant bisphosphonate (BP) ligands using carbodiimide coupling and chemoselective click reactions. Hydrogel is formed immediately after simple addition of silver (Ag+) ions to the solution of HA containing BP groups (HA-BP). Compared with previous HA-based wound healing hydrogels, the HA-BPĀ·Ag+ hydrogel is highly suitable for clinical use as it can ļ¬ll irregularly shaped wound defects without the need for premolding. The HA-BPĀ·Ag+ hydrogel shows antimicrobial ...

Objectives: Direct pulp capping is a treatment for preserving the vital pulp. However, a satisfactory material for caries-exposed inflamed pulp in permanent teeth is not currently available. Thus, a biologically-based material that promotes the continued formation of a new dentin-pulp complex is needed. A hydrogel drug delivery vehicle is a promising material, however its cytotoxicity has barely been explored. The aim of this study is to evaluate the cytotoxicity of a hydrogel drug delivery vehicle and its components in a cell culture system in vitro. Methods: The hydrogel solution was prepared by mixing poly(ethylene glycol)maleate-citrate (45% w/v)[PEGMC], acrylic acid (5% w/v)[AA], 2,2-Azobis(2-methylpropionamidine) dihydrochloride photoinitiator (0.1% w/v)[AAPH], and deionized water. Various concentrations of the hydrogel and its components were prepared in the cell culture medium. L929 cells were seeded into 96-well plates at 3x103 cells/well and cultured with each concentration of the ...

Taking medication often comes with side effects which range in severity which may even deter people from seeking treatment. Accordingly, there is a need for improved efficiency in drug delivery which can be achieved with the use of a nanoparticle drug delivery system. In order to manufacture drug delivery hydrogel particles at a nanoscale, the behavior of the system must first be understood fundamentally. This study focused on quantifying the amount of a drug, chosen to be DL-propranolol hydrochloride, that diffuses into a poly(n-isopropylacrylamide) (PNIPAm) hydrogel at equilibrium. Three gels were synthesized and soaked in a solution containing DL-propranolol hydrochloride for 14 days, which was found to be the amount of time needed for the drug to reach equilibrium (complete diffusion). After this time period, the gels were then sliced into disks in order for the drug to be extracted. Using UV-visible spectroscopy, the concentration of drug in each disk was analyzed. This data, along with the ...

Due to our aging population, an increase in proximal femur fractures can be expected, which is associated with impaired activities of daily living and a high risk of mortality. These patients are also at a high risk to suffer a secondary osteoporosis-related fracture on the contralateral hip. In this context, growth factors could open the field for regenerative approaches, as it is known that, i.e., the growth factor BMP-7 (bone morphogenetic protein 7) is a potent stimulator of osteogenesis. Local prophylactic augmentation of the proximal femur with a BMP-7 loaded thermoresponsive hydrogel during index surgery of an osteoporotic fracture could be suitable to reduce the risk of further osteoporosis-associated secondary fractures. The present study therefore aims to test the hypothesis if a BMP-7 augmented hydrogel is an applicable carrier for the augmentation of non-fractured proximal femurs. Furthermore, it needs to be shown that the minimally invasive injection of a hydrogel into the mouse femur is

Three-dimensional hydrogel is suitable for targeted investigation of amoeboid migration of glioma cellsThree-dimensional hydrogel is suitable for targeted investigation of amoeboid migration of glioma cells
Glioblastoma (GBM) invasion and migration are key biological behaviors leading to refractoriness to current therapies and infiltration into the nonā€‘tumor brain parenchyma. GBM cell migration is strongly dependent on tumor architecture in vivo, which is absent in traditional twoā€‘dimensional (2D) monolayer culture. The present study applied a threeā€‘dimensional (3D) hydrogel model to rebuild the tumor architecture in vitro. Treatment with NSC23766, a specific inhibitor of Rasā€‘related C3 botulinum toxin substrate 1 (Rac1), inhibited the mesenchymal invasiveness however triggered the amoeboid motility called mesenchymalā€‘amoeboid transition (MAT). Notably, NSC23766 stimulated U87 GBM cell migration in the 3D hydrogel. However, this compound inhibited cell motility in 2D monolayer culture without tumor architecture for MAT, suggesting the advantage of 3D hydrogel to investigate tumor cell invasion. Due to the inverse interaction of Rac1 and Ras homolog family member A (RhoA) signaling in the ...

Inhomogeneous large deformation study of temperature-sensitive hydrogel | ScholarBank@NUSInhomogeneous large deformation study of temperature-sensitive hydrogel | [email protected]
In this paper, inhomogeneous deformation of a temperature-sensitive hydrogel has been studied and analyzed under arbitrary geometric and boundary conditions. We present the governing equations and equilibrium conditions of an isothermal process based on the monophase gel field theory of hydrogel via a variational approach. We have adopted and implemented an explicit form of energy for temperature-sensitive hydrogel in a three-dimensional finite element method (FEM) using a user-supply subroutine in ABAQUS. For verification purpose, a few numerical results obtained by the proposed approach are compared with existing experimental data and analytical solutions. They are all in good agreement. We also provide several examples to show the possible applications of the proposed method to explain various complex phenomena, including the bifurcation, buckling of membrane, buckling of thin film on compliant substrate and the opening and closure of flowers.

Two complementary Ī²-sheet-forming decapeptides have been created that form binary self-repairing hydrogels upon combination of the respective free-flowing peptide solutions at pH 7 and ,0.2 wt %. The component peptides showed little structure separately but formed extended Ī²-sheet fibres upon mixing, which became entangled to produce stiff hydrogels. Microscopy revealed two major structures; thin fibrils with a twisted or helical appearance and with widths comparable to the predicted lengths of the peptides within a Ī²-sheet, and thicker, longer, interwoven fibres that appear to comprise laterally-packed fibrils. A range of gel stiffnesses (G from 0.05 to 100 kPa) could be attained in this system by altering the assembly conditions, stiffnesses that covered the rheological properties desirable for cell culture scaffolds. Doping in a RGD-tagged component peptide at 5 mol % improved 3T3 fibroblast attachment and viability compared to hydrogel fibres without RGD functionalisation ...

Associated Challenges of Immunostaining Cells Encapsulated in Hydrogel Scaffolds | VisikolAssociated Challenges of Immunostaining Cells Encapsulated in Hydrogel Scaffolds | Visikol
As 3D cell-based models continue to grow in popularity it is natural to try and apply existing 2D assays as a way of expanding experimental capabilities, but it is important to remember that large changes in model format can result in new experimental challenges that must first be overcome before useful data can be generated.. A common request that we often get at Visikol is if we can immunolabel microtissues encapsulated or grown in Matrigel; one of the first 3D cell culture options commercially available and a well know protein-based scaffold. Using Matrigel can result in cells expressing exciting biological phenotypes, but it can also introduce some unexpected complications with antibody labels. When immunolabeling tissues and microtissues the challenge is to get even labeling from the primary antibody. When you encapsulate tissues inside a hydrogel you have introduced an additional physical obstacle that the antibodies must first move through before they can begin to diffuse into the tissue. ...

Novel hydrogel composites for implant applicationNovel hydrogel composites for implant application
EN] Plasma-liquid electrochemistry was successfully used to synthesize gold nanoparticles in a watery background (AuNPs) and also embedded within a hydrogel network (PVA-AuNPs) without using any capping or reducing agents. Nanoparticles of different sizes and morphologies were obtained and the effect of the precursor concentration on the NPs size was examined. The effect of the hydrogel was also studied and it is though that it is responsible of stabilizing and avoiding the agglomeration of the NPs. This atmospheric-microplasma set-up was then used to create gold and silver mixed nanoparticles (Au-AgNPs) and PVA capped with these bimetallic nanoparticles (PVA-AuAgNPs). Their absorption properties were analysed using ultraviolet-visible (UV-Vis) spectroscopy and their size and shape using transmission electron microscopy (TEM). Antibacterial characteristics of the NPs embedded within the PVA matrix were also tested against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) showing a ...

Hydrogel Stretches and Contracts Like a Heat-driven MuscleHydrogel Stretches and Contracts Like a Heat-driven Muscle
These are pictures showing the changing shape of the hydrogel as it walks in a water environment in responses to changes of temperature. (Credit: Kim et al. Nature Materials). In research published in Nature Materials, a team led by scientists from the RIKEN Center for Emergent Matter Science in Japan has developed a new hydrogel that works like an artificial muscle-quickly stretching and contracting in response to changing temperature. They have also managed to use the polymer to build an L-shaped object that slowly walks forward as the temperature is repeatedly raised and lowered. Hydrogels are polymers that can maintain large quantities of water within their networks. Because of this, they can swell and shrink in response to changes in the environment such as voltage, heat, and acidity. In this sense they are actually similar to the plant cells, which are able to change shape as the amount of water within them changes in response to environmental conditions.. However, most hydrogels do this ...

Abstract 156: Hydrogel Mattress, an in vitro Platform to Enhance Maturation and Evaluate Contractile Function of Individual...Abstract 156: Hydrogel Mattress, an in vitro Platform to Enhance Maturation and Evaluate Contractile Function of Individual...
Human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CMs) have great potential as tools for human heart disease modeling and drug discovery. However, their contractile properties have not been routinely evaluated; as current methods are not accessible for most laboratories. We sought to develop a more efficient method to evaluate hiPSC-CM mechanical properties, at the single cell level. Individual hiPSC-CMs were cultured on a hydrogel based platform, termed the hydrogel mattress, and their cellular contractile properties evaluated using video-based edge detection. We found that hiPSC-CMs maintained on the mattress reproducibly exhibited robust cell shortening, in dramatic contrast to hiPSC-CMs maintained in a standard manner. We further found that contraction and peak cell shortening amplitude of hiPSC-CMs on mattress was comparable to that of freshly isolated adult ventricular mouse CM. Importantly, hiPSC-CMs maintained on the mattress exhibited several characteristics of a ...
