Fabrication of a glucose oxidase/multiporous tin-oxide nanofiber film on Prussian blue–modified gold electrode for biosensing

Herein, we propose a new approach to fabricate an enzyme electrode based on immobilization of glucose oxidase (GOD) with multiporous nanofibers (MPNFs) of SnO2 on Prussian blue (PB) modified gold (Au) electrode with chitosan. MPNFs of SnO2 were synthesized by electrospinning method from the tin. Pru...
