Forming an adhesive layer on a nanoimprint lithography template or a double-sided disk. Forming the adhesive layer on the double-sided disk includes immersing the double-sided disk in a liquid adhesive composition and removing the double-sided disk from the adhesive composition. The outer layer of the double-sided disk is a carbon overcoating or an intermediate layer. The adhesive composition is dried to form a first adhesion layer adhered directly to the carbon overcoating or intermediate layer on a first side of the disk and a second adhesion layer adhered directly to the carbon overcoating or intermediate layer on a second side of the disk. Forming the adhesive layer on the nanoimprint lithography template includes applying an adhesive material to the template, allowing the template to remain motionless, and rinsing a portion of the adhesive material from the template with a solvent, and drying the template.
A sensing interface for specific protein capture was fabricated using a novel molecular imprinting (MIP) process. Bovine serum albumin (BSA) and ovalbumin (OVA) were imprinted on a quartz substrate with modified alkyl groups, and target protein capture was detected using a deep-UV fluorescence image microscope (UVFLIM). The imprinted protein was immobilized to silica beads (diameter: 15 μm) using a phospholipid polymer containing both active ester groups and silane coupling groups, which were used as protein stamps to prepare the imprinting surface. Protein recognition sites were constructed by integrating sodium dodecyl sulfate (SDS) as the ligand, which was immobilized with a biocompatible photoreactive phospholipid polymer. When BSA solution was added to the BSA-based MIP substrate, strong fluorescence was observed from the tryptophan residue of BSA. In contrast, for the OVA-based MIP substrate and non-MIP substrate, no fluorescence was observed. The surface showed good selectivity of BSA ...
Molecular imprinting is a promising technique for the preparation of synthetic polymers of predetermined specificity. Function monomers are copolymerized with crosslinkers in the desired molecule, the imprinted molecule. Molecular imprinted polymers have been applied in an increasing number of fields including Separation, antibody and ceptor binding mimics, catalysis and artificial enzymes, biosensor-like devices. Besides, some problems and future research topics of this technique are discussed.
Novel analyte-responsive inverse-opal hydrogels (IOHs) based on molecular imprinting technology were fabricated to generate a highly selective and sensitive device for the colorimetric detection of tetracycline (TC). The TC-responsive IOHs were constructed by packing periodic silica-air arrays and then photo
Abstract: Molecular imprinting is an important tool for generating synthetic receptors with specific recognition sites. The resulting artificial receptor has been extensively used in areas that require molecular recognition. Nevertheless, various imprinted materials synthesized using conventional imprinting protocols have low binding capacities and slow binding kinetics because of difficulty in extracting the original templates and high resistance to mass transfer. The combination of molecular imprinting and nanostructured materials is expected to overcome such difficulties. In this work, template molecules were attached onto the electrospun fibers and by using electrospun nanofibers and attached molecules as sacrificial templates, surface molecularly imprinted membranes with bi-, tri- or tetramodal pore structures were fabricated in the absence or presence of SiO2 nanoparticles in the molecular imprinting precursor. As a demonstration, bovine serum albumin (BSA) and hemoglobin from bovine blood ...
Influenza virus H5N1, which caused the recent outbreak of avian flu, may have a new enemy. Researchers at the University of Marylands A. James Clark School of Engineering have created a "virus sponge" that could filter a patients blood in a process similar to kidney dialysis, removing the virus from the patients body. The concept could also be used to make vaccine production more efficient and in a pill to reduce glucose levels in diabetics, among other applications. The virus sponge is based on a technology called molecular imprinting. In molecular imprinting, researchers stamp a molecules shape into a substance (in this case, a hydrogel-a material that looks like a powder when dry; and like Jell-O when wet). When the specific molecule filters through the hydrogel, it fits in the imprint hole and is trapped. The research group of Peter Kofinas, a professor in the Clark Schools Fischell Department of Bioengineering, is the first to apply molecular imprinting to the capture of viruses, and ...

Cooperative binding is commonly observed in biological receptor systems. This study investigates whether it is possible to prepare nano-sized molecularly imprinted polymers (nanoMIPs) that show cooperative binding. NanoMIPs which exhibit cooperative binding would have increased affinity for immobilised template molecules making them useful for advanced applications in diagnostics and sensors. The use of a templatederivatised solid support provides a facile route to prepare nanoMIPs with surface imprints, and the method is ideally suited to study this topic. Although not observed during the course of this study, positive interbinding site cooperativity was hypothesised by way of an increase in the number of binding sites imprinted on the nanoMIPs, by increasing template density on the solid support surface. After synthesis, the affinity of nanoMIPs was analysed using surface plasmon resonance (SPR) technique. Under the conditions investigated, a ten fold increase in binding affinity was measured ...

Receptors generated by natural evolution in living organisms show an astonishing capacity for specifically recognizing target molecules. If applied as recognition units of biosensors, these receptors provide very high selectivity. However, they suffer from instability under measurement conditions, and low durability. Devising alternative robust artificial receptors circumvents these deficiencies. For instance, an antibody can be successfully replaced by a corresponding molecularly imprinted polymer (MIP), sometimes called a plastic antibody. Therefore, MIPs used as recognition units in chemical sensors are gaining increasing interest. In this review, we survey selected examples of MIPs used for determining target bioanalytes by mimicking natural recognition. For scientists working with biosensors, MIPs might be considered as alternatives to natural receptors, such as antibodies, enzymes, or histones.
The molecular imprinting techniques have been extensively studied for molecular recognition and their potential applications to separation and catalysis. The traditional imprinting method uses the crosslinking polymerization in the presence of a substrate molecule followed by grinding the bulk system to microparticles with an irregular shape. In addition, the imprinting is restricted to a hydrophobic substrate because the polymerization reaction is usually done in the organic solvent using hydrophobic monomers. In this case, the irregular shape and microparticle size might be a concern for microelectromechanical system (MEMS) application as a biosensor. In this study, we investigated a well-defined nanosphere with a core-shell structure for molecular imprinting. The hydrophilic substrates including D-glucose (D-Glu) or L-phenylalanine (L-Phe) were imprinted on the surface (shell) of nanosphere and their binding behavior were investigated. Their enantiomer (L-Glu or D-Phe) binding behavior to the ...
Small particles of polymeric material are produced by expansion of a mixture of monomers and a propellant. The size and shape of the particles can be precisely tailored by materials selection and expansion conditions. Particles of 10 nanometers to 100 microns can be produced. If monomers exhibiting solid state reactivity are utilized, the particles thus formed can be polymerized at any time after formation. The particles produced by this method can be molecularly imprinted by incorporating a template into the particle prior to fully curing the particle, in a manner which allows selective extraction of the template from the cured particle after formation without deformation of the imprint site. A two step polymerization process allows the particles to be deposited on and adhered to a wide variety of substrates without additional agents. The molecularly imprinted particles can be used in a wide variety of applications including the selective binding of analyte from a sample, where the analyte is the

As a proof of concept, we applied C60 fullerene adducts as such for the first time. For that, we derivatized C60 to bear either an uracil or an amide, or a carboxy addend for recognition of the adenosine-5-triphosphate (ATP) oxidizable analyte with the ATP-templated molecularly imprinted polymer (MIP-ATP). Accordingly, the ATP complex with all of the functional monomers formed in solution was potentiodynamically electropolymerized to deposit an MIP-ATP film either on an Au electrode of the quartz crystal resonator or on a Pt disk electrode for the piezoelectric microgravimetry (PM) or capacitive impedimetry (CI) determination of ATP, respectively, under the flow-injection analysis (FIA) conditions. The apparent imprinting factor for ATP was ~4.0. After ...

Contact lenses, as an alternative drug delivery vehicle for the eye compared to eye drops, are desirable due to potential advantages in dosing regimen, bioavailability and patient tolerance/compliance. The challenge has been to engineer and develop these materials to sustain drug delivery to the eye for a long period of time. In this study, model silicone hydrogel materials were created using a molecular imprinting strategy to deliver the antibiotic ciprofloxacin. Acetic and acrylic acid were used as the functional monomers, to interact with the ciprofloxacin template to efficiently create recognition cavities within the final polymerized material. Synthesized materials were loaded with 9.06 mM, 0.10 mM and 0.025 mM solutions of ciprofloxacin, and the release of ciprofloxacin into an artificial tear solution was monitored over time. The materials were shown to release for periods varying from 3 to 14 days, dependent on the loading solution, functional monomer concentration and functional monomer
The molecular imprinting is a process by which selected functional monomers that self-assemble around a master molecule and polymerize in the presence of a crosslinking agent.

With great sadness, we inform our colleagues and the scientific community of the decease of Prof. Dr. Denise P. Barlow. Denise died on October 21, 2017 at the age of 67 after severe illness in the company of friends. Denise Barlow was one of the most accomplished geneticists ever to operate in Austria and one of the most inspiring epigeneticists in Europe. Denise Barlow is one of the few researchers who could claim not only to have discovered a fundamental regulatory principle of eukaryotic gene expression, molecular imprinting, but to actually have elucidated the underlying mechanism.. In 1991, the Barlow group discovered the first mammalian imprinted gene (Igf2r) and since then, has worked relentlessly to uncover many fascinating details of the imprinting mechanism. As a result, imprinting of the Igf2r gene has acted as a model of epigenetic regulation in mammals. Her laboratory has shown that an unusual and very long non-coding RNA (lncRNA), a macro ncRNA, induces imprinted gene expression. ...
The turning point of modern immunological theory was the advent of the clonal selection theory (Burnet, Talmage - 1957). A useful heuristic in the classification of theoretical models was the contrast of instructive with selective models of the acquisition of information by biological systems. The neo-Darwinian synthesis of the 1940s had consolidated biologists model of evolution based on prior random variation and natural selection, viz. differential fecundity. While evolution in the large was by then pretty well settled, controversy remained about examples of cellular adaptation to chemical challenges, like induced drug-resistance, enzyme formation and the antibody response. While instructive theories have been on the decline, some clear cut examples can be found of molecular imprinting in the abiotic world, leading, e.g. to the production of specific sorbents. Template-driven assembly, as in DNA synthesis, has remained a paradigm of instructive specification. Nevertheless, the ...
Annealing of shape memory polymer. Movie showing the shape recovery of a polystyrene (PS) microparticle during annealing. Imaged using tapping mode on a MFP-3D with scan size 15 μm. The PS particle was flattened with a high-temperature, high-pressure nanoimprint lithography (NIL) process and then thinly coated with gold. The movie starts with the particle heated to 80°C. The temperature is rapidly stepped to 102°C, then over the course of three hours the temperature is gradually increased to 110°C. During annealing the particle diameter decreases and the height increases, recovering the original, pre-NIL spherical shape. A surface wrinkling morphology develops that gives information on recovery dynamics and strain energy release. Applications for micro- and nanoscale polymer particles include drug delivery and electronic packaging; incorporating shape memory effects could lead to many more.

Photonic crystal slabs (PCS) are one of the major transducers for label-free, optical biosensing applications. In this paper we present oblique-angle layer deposition of the high index slab material as a method to improve the PCS sensitivity. In simulations and experiments we consider PCSs composed of a high index silicon monoxide layer on a nanostructured resist layer on a glass substrate. By mounting the substrate at an oblique angle with respect to the evaporation source, the high index material distribution on the nanostructured surface is modified due to shadowing effects. Finite-difference time-domain (FDTD) simulations were performed to predict bulk and surface sensitivities. In order to verify the simulation results we fabricated PCSs at various deposition angles using nanoimprint lithography to replicate a linear grating nanostructure into the resist layer and thermal evaporation for a 60-nm silicon monoxide deposition. The bulk sensitivities of these structures were measured using ...
Protecting the human body from viral infections is extremely important for maintaining human health. To prevent viral infections, early diagnosis is important. Moreover, the diagnosis must also be non-invasive and non-painful. Hence, for development of novel analytical systems for protecting from viral infections, non-invasive biosensing devices with high sensitivity and high throughput are effective analytical systems that can be conveniently used to make a diagnosis. For establishment of novel analytical systems, photonic crystal (PC) can be used to observe nanometer-sized periodic structures, and their structural color can be used to realize on-site non-invasive biosensor. In this study, we have demonstrated the reflectometric detection of influenza virus in human saliva using antibody-immobilized flexible nanoimprint lithography (NIL)-based two-dimensional (2D)-PC biosensor. As a result, using antibody-immobilized 2D-PC biosensor, reflection intensity change which related with influenza ...
By exploiting nanoimprint lithography, we fabricated biocompatible plastic GRs of varying periodicity suitable for high-resolution microscopy and investigated neurite contact guidance of an invertebrate neuronal model (leech neurons). Using high-resolution fluorescence microscopy, we quantitatively compared the changes in tubulin cytoskeleton organization and cell morphology induced by mechanotransduction. The neuritic development and filopodium organization at the GCs were also studied in response to topographical guidance. This in vitro model was finally compared and validated with several other neuronal cells, from embryonic stem cells and primary hippocampal neurons to human neuroblastoma differentiated cells, which were interfaced with similar GRs.. Leech neurons could read the directional topographical information of T2 and T4. In particular, cell and neurite network alignment was more efficient on T4 than on T2 and neuron morphology was less branched, in agreement with [44]. The GCs were ...

Self-assembling molecules use hybrid polymers, called block copolymers, composed of segments that repel each other. Coated as a thin film on a properly prepared surface, the segments line up into perfect rows. The size of the polymer segments determines the row spacing. After polymer patterns are created, a chip-industry process called line doubling makes the tiny features even smaller, creating two separate lines where one existed before. The patterns are then converted into templates for nanoimprinting, a precision stamping process that transfers the nanometer-scale pattern onto a chip or disk substrate. A key challenge proved to be preparing the original surface so the block copolymers form their patterns in the radial and circular paths necessary for rotating disk storage. HGST is the first to combine self-assembling molecules, line doubling and nanoimprinting to make rectangular features as small as 10 nanometers in such a circular arrangement ...

A novel monodisperse molecularly imprinted shell was prepared based on surface imprinted hollow vinyl-SiO2 particles and applied to selective recognition and adsorption of estradiol (E2). This method was carried out by introducing vinyltriethoxysilane to the surface of polystyrene (PS) spheres by a simple one-step modification, followed by dissolution to remove the PS cores, and then by copolymerization of functional monomers via surface imprinted on the hollow vinyl-SiO2 particles to prepare uniform E2-imprinted shells. Two interesting characteristics were found: first, the obtained hollow molecularly imprinted polymer shells (H-MIPs) had highly monodispersity, uniform spherical shape with a shell thickness of about 40 nm; and then, the method was simple, easy to operate by directing coating of a uniform shell on hollow particles via surface imprinting. The resultant H-MIPs demonstrated improvements in imprinting factor and binding kinetics, owing to the high selectivity to template molecules, surface

Antibiotic drugs save lives. But we simply use them too much - and often for non-lifesaving purposes, like treating the flu and even raising cheaper chickens. The result, says researcher Ramanan Laxminarayan, is that the drugs will stop working for everyone, as the bacteria they target grow more and more resistant. He calls on all of us (patients and doctors alike) to think of antibiotics - and their ongoing effectiveness - as a finite resource, and to think twice before we tap into it.
