ELECTROCHEMICAL NANOCOMPOSITE BIOSENSOR SYSTEM

摘要

An electrode useful in electrochemical nanobiosensors for determining the presence or concentration of analytes in aqueous samples. In particular, the electrode comprises a biocatalyst or other bioreceptor entrapped in a conducting polymeric film deposited on a conducting material, and a non-conducting or conducting porous coating. In particular embodiments, the conducting polymeric layer also comprises metallic nanoparticles. Electrochemical nanobiosensors containing the electrode, methods of making the electrode or sensor and methods of detecting analytes are also disclosed.
