Paper Abstract

This paper describes development of the modular microfluidic components and their integration, directed toward the development of an electrochemical immunoassay-based bio-chemical detection system. The entire system consists of an array of fluid reservoirs, microfluidic valves & pump, a sampling/reaction chamber with integrated electromagnetic filterless bio-separator and a detection chamber comprising of the filterless bio-separator and an immunosensor. The magnetic beads are used to capture and detect the target toxins/molecules. This paper discusses the performance of the fluidic components and presents the preliminary results and packaging aspects of the 1st generation fluidic system. The effect of component size on system performance is also discussed.
