During the last decade, the advancement of microrobotics has provided a powerful tool for micromanipulation in various fields including living cell manipulation, MEMS/MOEMS assembly, and micro-/nanoscale material characterization. Several dexterous micromanipulation systems have been developed and demonstrated. Nowadays, the research on micromanipulation has shifted the scope from the conceptual system development to the industrial applications. Consequently, the future development of this field lies on the industrial applicability of systems that aims to convert the micromanipulation technique to the mass manufacturing process. In order to achieve this goal, the automatic microrobotic system, as the core in the process chain, plays a significant role. This thesis focuses on the calibration procedure of the positioning control, which is one of the fundamental issues during the automatic microrobotic system development. A novel vision based procedure for three dimensional (3D) calibrations of ...
We compare the measurements of viscoelastic properties of adherent alveolar epithelial cells by two micromanipulation techniques: (i) magnetic twisting cytometry and (ii) optical tweezers, using microbeads of same size and similarly attached to F-actin. The values of equivalent Young modulus E, derived from linear viscoelasticity theory, become consistent when the degree of bead immersion in the cell is taken into account. E-values are smaller in (i) than in (ii): ∼34-58 Pa vs ∼29-258 Pa, probably because higher stress in (i) reinforces nonlinearity and cellular plasticity. Otherwise, similar relaxation time constants, around 2 s, suggest similar dissipative mechanisms. ...

Microelectromechanical systems (MEMS) are tiny machines built with techniques derived from the microelectronics industry. Very large numbers of MEMS can be conveniently fabricated in parallel. However, the control and assembly of such massively parallel microsystems gives rise to numerous challenges in modeling, algorithms, as well as in physical implementation.. In this presentation, we explore parallel micromanipulation and microassembly by investigating a cilia-like micro conveyor, a precision docking system for future "pico-satellites", a walking microchip, and self-assembling micro devices.. ...
Recording and stimulation. The experimental arrangement was mounted on a gas-driven vibration isolation table (Technical Manufacturing, Peabody, MA) inside a Faraday cage. Using a stereomicroscope, VS-3 receptor cells were identified through a thin layer of saline. A horizontal puller (P-2000; Sutter Instruments, Novato, CA) was used to pull microelectrodes from borosilicate glass (1 mm outer diameter, 0.5 mm inner diameter). Electrodes (3 m KCl, 45-70 MΩ) were positioned with a micromanipulator (Leitz, Wetzlar, Germany) above a neuronal soma. Cell penetration was achieved by gentle tapping of the micromanipulator. All electrical recordings were done with the switching single-electrode technique in either current- or voltage-clamp mode [duty cycle, 1:8 stimulating/recording; switching frequency, 20 kHz; SEC-05LX amplifier (NPI Electronic, Tamm, Germany)]. Details of the recording technique have been given by Torkkeli and French (1994).. For mechanical stimulation a piezoelectric stimulator ...
Some cells have a quality control checkpoint that can detect a single misattached chromosome and delay the onset of anaphase, thus allowing time for error correction. The mechanical error in attachment must somehow be linked to the chemical regulation of cell cycle progression. The 3F3 antibody detects phosphorylated kinetochore proteins that might serve as the required link (Gorbsky, G. J., and W. A. Ricketts. 1993. J. Cell Biol. 122:1311-1321). We show by direct micromanipulation experiments that tension alters the phosphorylation of kinetochore proteins. Tension, whether from a micromanipulation needle or from normal mitotic forces, causes dephosphorylation of the kinetochore proteins recognized by 3F3. If tension is absent, either naturally or as a result of chromosome detachment by micromanipulation, the proteins are phosphorylated. Equally direct experiments identify tension as the checkpoint signal: tension from a microneedle on a misattached chromosome leads to anaphase (Li, X., and R. ...

TY - JOUR. T1 - Omnidirectional actuation of magnetically driven microtool for cutting of oocyte in a chip. AU - Inomata, Naoki. AU - Mizunuma, Takehito. AU - Yamanishi, Yoko. AU - Arai, Fumihito. PY - 2011/4/1. Y1 - 2011/4/1. N2 - In this paper, we developed and fabricated a magnetically driven microtool (MMT) and installed it on a microfluidic chip for use in the enucleation of oocytes. The fabricated tool is much smaller than a conventional mechanical micromanipulator used for cell manipulation. We succeeded in driving this MMT in two degrees of freedomin the X - and Y -directions. The MMT works on the principle of noncontact actuation by magnetic force; therefore, the microfluidic-chip part is fully disposable and inexpensive. The MMT consists of a polymer part with a controllable attitude and a rigid metal (Ni) part with good magnetic properties, which are useful for cutting oocytes. We analytically evaluated that the structure for easy attitude control of the polymer part is a ...

laser-heating scenario ahead of a progressing cut to "actively" induce compressive thermoelastic stresses to control fracture of a cantilevered plate was developed with guidance from numerical simulations. Simulations of the active-stressing approach were achieved by using a customized finite-element formulation that was previously employed to model dual-beam laser machining. However, in this instance probabilistic fracture-mechanics was used to quantify the influence of the induced compressive-stresses on the time and nature of the fracture. Experiments were also conducted to test the feasibility of the active-stressing approach. The effect of important parameters such as the beam diameter, incident power density, and the positioning of the second beam with respect to the progressing cut was then studied with the goal of reducing and∕or delaying the likelihood of fracture.. ...
the penguin is a compact optical beam deflection sensor used to monitor the deflection of a cantilever whose long axis is parallel to the optical axis of a conventional optical microscope. this allows for a sample, such as a myofibril filament, to be imaged by the optical microscope while forces exerted by it on the cantilever can be measured with very high temporal resolution (well beyond video rate) and very high precision (not limited by the image pixel size).. the optics and electronics necessary for cantilever detection are encased in the penguin, shown below. The digital control and data acquisition is performed by custom designed labview software by tiberius brastaviceanu.. a temperature regulated bath (shown below) mounted on the microscope stage provides the working environment for the sample to be studied. micromanipulators on either side of the penguin manipulate the cantilever and a glass needle to tether the sample at both ends at the beginning of the experiment.. ...

Many researchers have studied the effects of changing the surface on fouling and cleaning. In biofouling the Baier curve is a well-known result which relates adhesion to surface energy, and papers on the effect of changing surface energy to food fouling can be found more than 40 years ago. Recently the use of modified surfaces, at least at a research level, has been widespread. Here two different ways of studying surface-deposit interactions have been compared. Atomic force microscopy (AFM) is a method for probing interactions at a molecular level, and can measure (for example) the interaction between substrate and surfaces at a nm-scale. At a μm-mm level, we have developed a micromanipulation tool that can measure the force required to remove the deposit; the measure incorporates both surface and bulk deformation effects. The two methods have been compared by studying a range of model soils: toothpaste, as an example of a soil that can be removed by fluid flow alone, and confectionery soils. ...

The trapping source for the Optical Tweezers System is a power- and wavelength-stabilized 1064 nm laser, which is split into two independently steerable trapping beams with greater than 1 W optical power per beam. Each beam can support several time-shared traps. Other trapping wavelengths and powers are available for specialized applications.. The output of the trapping laser is collimated, and the light is focused onto the sample with diffraction-limited performance, thereby achieving optical gradients capable of trapping particles. Force measurements in the femtonewton to piconewton range can be performed using the included force measurement module. Quadrant detectors monitor a signal sensitive to the relative displacement of the trapped particle from the laser beam axis. As a result, the output of the detector can be used to calibrate the position, stiffness, and force of the optical tweezers. Force measurements with optical tweezers have enabled quantitative studies in diverse areas, such as ...

Patch pipettes were mounted onto a pipette holder and amplifier head stage (Axon Instruments Inc., Union City, CA; Axopatch 200B), which were connected to micromanipulators (Narashige International Inc., East Meadow, NY). The indifferent electrode was an Ag-AgCl plug submerged in the bath. Positive pressure was applied to the pipette as it was lowered into the bath to prevent clogging the tip with debris. The pipette was advanced until it began to form a seal with the cell membrane, which was seen as an increase in resistance. A brief period of suction created a gigaohm seal between the pipette and the cell membrane. Pipette capacitance was canceled at this stage. Once a gigaohm seal was formed, whole cell access to the inside of the cell was obtained by rupturing the membrane under the pipette tip. The bath solution was of the following composition: 120 mm NaCl, 4.8 mm KCl, 1.2 mm KH2PO4, 25 mm NaHCO3, 5 mm HEPES, 5.5 mm dextrose, and 2 mm CaCl2, equilibrated with 95% O2-5% CO2. Strychine, ...

In this paper, for the first time, we report on systematic theoretical and experimental investigation of Phase Contrast Optical Tweezers (PCOT) which could be an indispensable tool for micromanipulation of the transparent micro and nano objects such as biological tissues and vesicles. The quadrant photodiode detection scheme and the power-spectrum calibration method is shown to be valid for this case. We have shown that the phase objective with new designed phase plates can provide nearly aberration-free condition at a desired depth. This could be a valuable advantage for simultaneous in-depth micro-manipulations and visualization of the sample.. ©2010 Optical Society of America. Full Article , PDF Article ...

Quantum computers have the capability of out-performing their classical counterparts for certain computational problems1. Several scalable quantum-computing architectures have been proposed. An attractive architecture is a large set of physically independent qubits arranged in three spatial regions where (1) the initialized qubits are stored in a register, (2) two qubits are brought together to realize a gate and (3) the readout of the qubits is carried out2, 3. For a neutral-atom-based architecture, a natural way to connect these regions is to use optical tweezers to move qubits within the system. In this letter we demonstrate the coherent transport of a qubit, encoded on an atom trapped in a submicrometre tweezer, over a distance typical of the separation between atoms in an array of optical traps4, 5, 6. Furthermore, we transfer a qubit between two tweezers, and show that this manipulation also preserves the coherence of the qubit. ...

Denuding micropipettes used for denudation, and the manipulation and transfer of gametes and embryos. Each pipette is hand-made with borosilicate glass, known for its high stability and resistance to corrosion. Glass pipettes reduce the chance of oil drops attaching inside the pipette and damaging the oocyte or embryo compared to plastic pipettes. Available with polished or unpolished glass. Unpolished pipettes are ideal for denudation of the cumulus cells attached to the zona pellucida prior to micromanipulation procedures. Polished glass pipettes are ideal for transfering blastomeres, oocytes, and embryos during assisted reproductive procedures.
Many organs adapt to their mechanical environment as a result of physiological change or disease. Cells are both the detectors and effectors of this process. Though many studies have been performed in vitro to investigate the mechanisms of detection and adaptation to mechanical strains, the cellular strains remain unknown and results from different stimulation techniques cannot be compared. By combining experimental determination of cell profiles and elasticities by atomic force microscopy with finite element modeling and computational fluid dynamics, we report the cellular strain distributions exerted by common whole-cell straining techniques and from micromanipulation techniques, hence enabling their comparison..

We present a bidirectional electrothermal microgripper for the advanced manipulation of single large cells. The device demonstrates excellent performance, and shows great potential as a supporting microtool for different biomedical procedures such as oocyte selection or electrofusion of cells. In particular, we focus on the operation of the device in real environments, i.e. integrated in a standard biological micromanipulation station and entirely submerged in a biological fluid, for the handling and transportation of live specimens (in our case mice oocytes). A clamping mechanism is included in the design that limits the pressure exerted over the biological specimen to an approximate maximum of 40 μN, whilst maintaining a robust grip, with a force up to 300 μN, between the arms of the microgripper.. ...
In this paper, we present the design and development of an integrated micro-force-sensing probe with a piezoresistive sensor at its core. By bonding an etched optical fibre on the beam of the core sensor, the dimension of the sensing probe is substantially reduced. Experiments are conducted on a prototype photonic assembly system to qualify and demonstrate the applicability of this sensor. Results from the experiments show that this integrated probe sensor has good sensitivity and linearity, and larger measurement range. Such experimental results provide evidence that the integrated probe sensor represents a cost-effective force-sensing solution for micromanipulation. © 2006 IOP Publishing Ltd ...

You should treat a good pair of tweezers like a precision instrument. Many manufacturers hand-tool their products and guarantee their sharpness and alignment. Alignment refers to the position of one tip relative to the other. When tweezers are aligned at the factory, the tip centers come together precisely. This leads to more force being transmitted to the hair, which results in more effective, less painful plucking. If you drop a pair of tweezers, you can affect the alignment or damage the tip. So dont throw your tweezers carelessly into a drawer or medicine cabinet. And always place the protective cap back on the tips.. By the same token, you should also respect your own health and safety when tweezing. Tweezer tips are extremely sharp, so dont dig too vigorously in your mission to snag every stray hair. You should also keep tweezers away from children, who might accidentally injure themselves or others. And dont forget to clean your tweezers after each use. Wipe the tips clean with a ...
ANGLÈS] Living cells contain different charged groups such as membranes, nucleus, histones, etc. The interaction of these groups with electric fields will afect the basic properties and behavior of cells by determining how they communicate, grow or difuse. In this work we measure the electrophoretic mobility (EPM) of single yeast cells during normal growth and at different growth stages under hyperosmotic stress using a combination of optical tweezers and a position detector. In the first case we find that EPM shows a non-monotonic behavior during the cell cycle; in the second case we find that in spite of the few morphological changes observed, the EPM presents important variations depending on the time spent under hyperosmotic stress conditions ...
