| dc.description.abstract | This thesis presents the development of a high-throughput microfluidic microorganism concentrator for pathogen detection applications. Interdigitated electrodes lining the bottom of the channel use positive dielectrophoretic forces to trap particles. A passive mixer is used to circulate the liquid in the channel, transporting particles to within the trapping region of the electrodes. Samples are extracted and their concentrations measured using a spectrophotometer. Concentration enhancements up to 40x at 500 gl/min flowrate using polystyrene microspheres and up to 10x at 100 gll/min flowrate using B. subtilis spores are achieved. | en_US |
