ABSTRACT
Biosensors are relatively new to the field of diagnostic reagents. Despite advances in biosensors, dry chemistry dominates and may continue to dominate as the primary choice for analyte detection in body fluids, e.g., blood. The main reason is economics. Dry reagents are much less expensive than biosensors, both in developmental and manufacturing costs. Essentially, a biosensor is a device that incorporates a bioactive substance, e.g., an enzyme or antibody that specifically recognizes an analyte, in contact with a transduction system.
