The need for highly sensitive, quick and reliable detection of pathogens in food and water sources is an important topic for the safety of our food and water supplies.  Research in the area of microfluidics has targeted real time cell detection and has already solved some of these problems by creating various separation and detection devices.  In this study we will develop an impedance based counting method for near real time detection of targets.  Our device is focused on using a simple electrode design to measure resistance changes within our fluid with minimal post-processing of the collected data.  The proof-of-concept will be demonstrated using a model particle and the analytical characteristics will be investigated. Its application for real pathogen detection will be explored.
