We describe methods and results of simulations done for predicting behavior of particles in an aqueous solution under an applied AC electric field on electrodes of rectangular and triangular shapes. Here the two major effects which come into play are Dielectrophoresis and AC ... Mehr lesen

Shear Stress Analysis in High-Throughput Dual-micropillar-based Microfluidic Platform

J.Borana[1], J.M.Lee[2], B.G.Chung[2]
[1]Indian Institute of Technology Guwahati, Guwahati, India
[2]Department of Mechanical Engineering, Sogang University, Seoul, Korea

We developed the dual-micropillar-based microfluidic platform to control cellular behavior. The 4×4 dual micro-pillar based platform consists of 16 circular-shaped outer micropillars and 8 saddle shaped inner-micropillars. We simulated various shapes of inner micropillars to analyze the ...

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation

L. Helmich[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Mehr lesen

Simulation of Rarefied Gas Flow in the KATRIN Source

L. Kuckert[1]
[1]Karlsruhe Institute of Technology, Karlsruhe, Germany

The KATRIN experiment at the Karlsruhe Institute of Technology (KIT) will measure the neutrino mass on a sub-eV range. Therefore the electron spectrum of the beta decay of Tritium will be detected and compared with a simulated spectrum of the used windowless gaseous Tritium source ... Mehr lesen

Modelling of a Single Cardiomyocyte Interaction with a Microcantilever Using COMSOL Multiphysics®

I. Banerjee[1]
[1]Tampere University of Technology, Tampere, Finland

: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are ... Mehr lesen

Can Oscillatory Convection Accelerate Signal Propagation in Simple Epithelium?

M. Nebyla[1], M. Pribyl[1]
[1]Institute of Chemical Technology, Prague, Department of Chemical Engineering, Prague, Czech Republic

We introduce a mathematical model of signal transmission in simple epithelial layers. The mathematical model consists of reaction-transport equations for extracellular ligands, cellular receptors, ligand-receptor complexes and a ligand releasing protease. We consider diffusion and ... Mehr lesen
