The response characteristics and ideal operating conditions are described for a novel fiber-optic internal enzyme biosensor for hydrogen peroxide. The sensing mechanism involves hydrogen peroxide entering an enzyme containing internal solution by crossing a gas-permeable membrane. Once in the intern

A novel sensor for the selective detection of hydrogen peroxide is described. This sensor is based on the internal enzyme concept configured in a gas-sensing arrangement. Hydrogen peroxide diffuses across a microporous PTPB membrane and enters the internal solution. The entering hydrogen peroxide is
