US Patent 7166208 Apoenzyme reactivation electrochemical detection method and assay

The invention discloses a methods in which dry reagent enzyme based electrochemical biosensors, which are in a relatively mature form due to the extensive amount of development pioneered by the blood glucose monitoring industry, may be simply adapted to perform tests for blood coagulation, enzymatic activity, or immunochemical assays for antigens present in a fluid sample. In particular, the utility of combining apoenzyme based dry reagent electrochemical biosensors with apoenzyme reactivation technology is taught. This combination creates a novel combination dry reagent test technology capable of detecting a wide range of different analytes.
