Abstract
Microfluidic devices allow for the manipulation of fluids, particles, cells, micro-sized organs or organisms in channels ranging from nano to submillimeter scales, with volumes spanning from microliters to picoliters. The use of these micro-sized networks of channels and chambers enables the use of distinctive phenomena characteristic of fluids in small dimensions. Our research group has developed hybrid polyethylene terephthalate laminate (PETL) microfluidic devices that are derived from polymer film and other low-cost materials to fabricate a biosensor. These membrane-based sensors can be used for the rapid detection of infectious agents contingent on their size and surface antigens in a small amount of bodily fluid. This technology is aimed to provide an affordable and accessible approach for effective pathogen detection in low-resource environments. The detection of red blood cell agglutination was used to test the functionality of the biosensors. The use of PETL devices was further explored through the development of a bioreactor that facilitates the controlled growth of bacteria within microfluidic architecture.
