Direct Electrochemistry of Catalase Immobilized at Polymerized-SnO2 Multiporous Modified Electrode for an Amperometric H2O2 Biosensor

A novel amperometric H2O2 biosensor based on immobilization of catalase with polymerized MPNFs of SnO2 onto glassy carbon electrode with chitosan have been proposed in this work. Multiporous nanofibers of SnO2 were synthesized by electrospinning method from the tin precursor by controlling the conce...
