Biosensor development at the University of Utah

Describes three biosensors: a silicon retina chip, CHEMFET sensors and an optical immunoassay chip utilizing a planar waveguide. These three examples of sensors give a small flavor of the biosensor work ongoing at the University of Utah. Although there are obvious differences between each of these three sensors in terms of their application areas, the parameters measured, and the technologies used, there are several similarities that are shared by many biosensor developments. These include the move toward smaller device sizes, inexpensive fabrication, large-scale manufacturing methods, and improved reliability in actual applications. The extent to which each of these sensors can meet those real-world requirements will largely determine their eventual commercial viability.<
