Abstract

Lab-On-a-Chip systems are one of the new growing technologies which offer miniaturization of analysis systems. In this paper we present a simple and low cost fabrication of a micro filter using in different applications in Micro Total Analysis Systems. This method uses typical microscopic glass slides as a substrate for fabrication of micro filters for Lab-On-Chip applications. Based on flow control, micro channel and micro filter design particle separation is performed by hydrodynamic filtration. This micro filter allows the target particles to flow through and unwanted larger particles flow to other micro channel. Particularly, separation of different particles from automobile oil, based on particle size is studied. This device can also be used for other biomedical applications such as cell separation. The geometry of this filter eliminates the clogging effect that is an important factor in micro filter designs.
