Molecular electronic technology for biosensors

Summary form only given. A molecular-electronic biosensor device has been assembled by depositing a monolayer of glucose oxidase on a platinum electrode surface and by electrochemical polymerization of pyrrole to form a molecular film of polypyrrole in between the deposited glucose oxidase molecules. The polypyrrole has been found to work as a molecular interface to enhance electron transfer between glucose oxidase and the platinum electrode. Essentially, the molecular interface enables the enzyme to communicate with the electrode. The enzyme glucose sensor has been fabricated and characterized
