Abstract :
The authors have proposed a new method to concentrate bacteria flowing in a microchannel by using negative dielectrophoretic force generated by using a thin dielectric layer. In this study, it was demonstrated application of the bacteria concentration to improve throughput of optical detection of bacteria in microchannel.
