Abstract

We present a procedure for simultaneous deposition of enzyme-laden chitosan/reduced graphene oxide (rGO) film by electrophoretic deposition (EPD) for fast and efficient detection of glucose. The role of rGO nanosheets is studied on the EPD kinetics of the enzyme-laden suspensions. Investigating the performance of the biosensor by electrochemical techniques indicates its high sensitivity (9700 μA.mM−1.cm−2), low limit of detection (4 µM), and suitable selectivity.
