Modeling, Analysis and Design of Centrifugal Force Driven Transient Filling Flow into Rectangular Microchannel

Kim D.S., Kwon T.H., Pohang University of Science and Technology, KR

In this paper, we first present successful modeling and analysis results of a centrifugal force driven transient filling flow into a rectangular microchannel. Two types of exact and pseudo-static approximate solutions were derived for the [...]

Design, Modelling and Simulation of a PZN-PT Actuated Micropump

Malleo D., Haas C., Kraft M., University of Southampton, Microelectronics Group, UK

We present an optimization methodology for the design of a self-priming piezoelectrically actuated pump made of a borosilicate glass bonded to silicon. New findings in the design optimization of the piezo-actuated membrane are presented: it [...]

A Novel Microrheometer for Measuring Rheological Properties of Microquantities of Fluids

Lo C.S., Prewett P.D., Ward M.C.L., Docker P.T., University of Birmingham, UK

This paper describes a novel micromachined microrheometer, designed to measure the rheological properties of micro quantities of fluids. Measurements are achieved by monitoring the movement of superparamagnetic microbeads whilst in suspension in fluid when placed [...]

The Manufacture and Preliminary Testing of a Novel Bio-MEMS Filtration Chip

Docker P.T., Prince M., Kinnell P.K., Ward M.C.L., Ma X., Birmingham University, UK

In the clinical/microbiological laboratory there are currently several ways of separating specific cells from a fluid suspension. Conventionally cells can be separated based on size, density, electrical charge, light-scattering properties, and antigenic surface properties. Separating [...]

Mechanical Behavior of Micro-Drops in EWOD Systems: drop extraction, division, motion and constraining

Berthier J., Clementz Ph., Jary D., Raccurt O., Claustre P., Peponnet C., Fouillet Y., CEA-LETI, FR

We present a novel contribution to the design of electrowetting microdevices (EWOD) by using an energy minimization approach. Altough the dynamics of motion of microdrops by electrowetting may be rapid, it is shown that, due [...]

Modular Design Approaches for MicroFluidic Systems

Gilde M.J., van den Vlekkert H., Leeuwis H., Prak A., CapiliX BV, NL

The possibilities promised by microfluidic systems have not only interested scientists, but also industries, especially in the areas of the Life Sciences (food, medical, biotech) and fine chemistry (pharma) [2]. Microfluidics is the MEMS-field in [...]

Investigation of Volume of Fluids (VOF) Method and System Models for Design of Microfluidic Ink Delivery Apparatus for Dip Pen Nanolithography (DPN)

Banerjee D., Texas A&M University, US

DPN™ is a versatile technology that leverages Scanning Probe Microscopy for applications in biotechnology, photomask repair, molecular-electronics, nano-electronics and mask-less lithography(1). In earlier studies (2) the DPN process was augmented for biotechnology applications (genomics, proteomics) [...]

Fast and Sensitive DNA Hybridization Through Micro- Fluidics

Marafie A.H., Madou M.J., University of California Irvine, US

The research target for DNA hybridization through micro-fluidics is to achieve a fast and very sensitive hybridization reaction by investigating the effect of different pertinent parameters using computational and experimental methods. The mathematical model that [...]

Development of Microfluidic Device for Heterogeneous Immunoassay on Polystyrene Platform with Electroosmotic Control

Pribyl M., Snita D., Marek M., Institute of Chemical Technology Prague, CZ

We have developed a microfluidic device for heterogeneous immunoassay on the polystyrene platform. The wire-imprinting method has been chosen for the construction of microchannel structure of the chip. Immunoassay based on the interaction of fluorescently [...]

Thermal Modulation and Instability of Viscous Microjets

Furlani E.P., Eastman Kodak Company, US

Liquid microjets are inherently unstable and can be broken into droplets by various means including the modulation of pressure, velocity, and/or fluid properties. In this presentation we discuss the controlled breakup of viscous microjets via [...]
