Layout Verification by Extraction for Micro Total Analysis Systems

Baidya B., Mukherjee T., Carnegie Mellon University, US

The increasing complexity of MicroTotalAnalysis Systems is leading to a growing need for verification tools for such designs. Numerical simulation of such designs are slow, memory consuming and practically impossible for large designs. Schematic-based simulation [...]

Numerical Simulation of Microfluidic Flow Using a Combination of Micro and Macro Computational Techniques: Scaling Issues

Mautner T., SPAWAR Systems Center San Diego, US

Recent literature has demonstrated the possibilities of using configurable surfaces to enhance the flow of fluids in MEMS devices. Not only are surface properties important in fluid delivery, the inherent problems of mixing by diffusion [...]

Modelling and Optimization of Medical Test Strips Made From Plastics

Peters D., Bolte H., Laur R., University of Bremen, DE

Introduction In cooperation with industrial partners, a behavioural model for the microsystem ‚Medical Test Strips‘ has been created by the authors in order to decrease cost and effort in the design process. As there is [...]

A Study on the Novel Type of Ferrofluid Magnetic Pipette

Ahn J.J., Oh J., Choi B., Sogang University, KR

This study was performed to design the novel type of ferrofluid magnetic pipette on a micro scale for the purpose of applications to delivery systems, which is the core device of Lab on a chip [...]

Macromolecular Crystallization in Microfluidics for the International Space Station

Monaco L.A., Spearing S.F., Morgan Research Corporation, US

Macromolecular Crystallization in Microfluidics for the International Space Station At NASA’s Marshall Space Flight Center in Huntsville, Alabama, we have begun the development of scientific hardware for macromolecular crystallization on the International Space Station (ISS). [...]

Electrode Shapes for Electrowetting Arrays

Lienemann J., Greiner A., Korvink J.G., Albert Ludwig University, DE

We calculate the potential energy of an electrowetting array for different shapes and sizes of interdigital edge structures. To understand the dynamic effects at the beginning of the droplet motion is crucial for the optimization [...]

Microfluidic System For High-Throughput Proteomics

Le Gac S., Arscott S., Druon C., Tabourier P., Rolando C., USTL, FR

The comparative study of a cell type whole proteome in normal, pathological conditions or under the administration of drugs, which is called differential proteomics, appears as a keytool to understand diseases. To reach this goal, [...]

Microfluidic Technology Applied to Protein Sizing and Quantitation

Barthmaier P., Agilent Technologies, US

Although protein analysis technologies are developing fast, the current standard method is still denaturing gel electrophoresis (SDS-PAGE). Many researchers rely on this traditional method that has not substantially changed in the past 30 years. However, [...]

Coupling between Nanoscale and Microscale Modeling for MicroFluidic Devices

Jenkins J.W., Sundaram S., Makhijani V.B., CFD Research Corporation, US

Evaluation of microfluidic device and sensor designs using continuum modeling is a valuable method, but becomes more complex if nanoscale or molecular level physics must be included in the model. Recently, we have undertaken an [...]

Separation of Long Polyelectrolytes in a Microfuluidic Channel with Constrictions: A Monte Carlo Study

Tessier F., Slater G.W., University of Ottawa, CA

We present Monte Carlo simulation results for the motion of long linear polyelectrolytes inside a microchannel of molecular dimensions, structured as a periodic array of wells linked by narrow constrictions. Molecules are driven in the [...]
