We have been working on the development of a micro-fluidic DNA assay with the goal to quickly identify the introduction of PRRSv in pig herds in order to eliminate the transmission and spread of the virus. We have successfully designed and fabricated the components for DNA amplification, microfluidic transport, gel electrophoresis and optical detection with on-chip waveguides. Research into more durable waveguides is needed in order to fabricate a field unit. The realization of all the individual modules is an important step towards the complete fabrication and integration of an inexpensive DNA microanalysis platform for fast and accurate identification of target DNA molecules that will be amendable for field applications.
