Abstract

Modelling and simulation of capillary driven flows in microfluidic system components S. Halstenberg*, A. Quinte*, H. Eggeif, C. Schon^, R.-R Peters^ ^Institutfur Angewandte Informatik / Automatisierungstechnik, Universitat Karlsruhe, Germany ^ Institut fur Angewandte Informatik, Forschungszentrum Karlsruhe, Germany ^microParts Gesellschaft fur Mikrostrukturtechnik mbH, Dortmund, Germany Abstract Today, medical test strips are used for rapid diagnostics and the quick and easy determination of biomedically relevant parameters, such as the content of glucose of the blood. For the transport of the test fluid into the test strip the capillary effect will be made use of. Conventional test strips consist of an absorbent fleece (e.g. nitro cellulose), such that the capillaries inside the test strips are distributed statis- tically. Because of this, it is not possible to control the flow selectively. However, the technical progress achieved in microsystems engineering in the past yea
