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 of analyte detection in body fluids, e.g., blood. The main reason is economics. Dry reagents are less expensive than biosensors, in both developmental and manufacturing costs. Essentially, biosensors are analytical sensing devices for quantitatively measuring specific body analytes, e.g., blood glucose.
