Implementation of Cell Detection Mechanism on Microfluidic Chip

The paper describes development of a compact and economical sensing system to detect a cell in a micro channel which can be integrated easily on a micro PDMS (polydimethylsiloxane) chip. The light-intersecting method is adopted for detecting a cell moving in the channel, since the mechanism can be basically composed of only a light source element and a detector. The paper proposes an integrating procedure and shows the experiment in order to bear out feasibility of the system. Furthermore, a method of implementation of the mechamism on a micro PDMS chip is described.
