Abstract

The Mn₂O₃-Ag nanofibers were fabricated by electrospinning PVP sol-gel solution containing Mn(NO₃)₂ and AgNO₃, followed by calcination in air at 500 °C for 3 h. The as-prepared Mn₂O₃-Ag nanofibers were employed as the immobilization matrix for glucose oxidase (GOD) to construct an amperometric sensor for glucose detection in pH 7 phosphate buffer. The Mn₂O₃-Ag-GOD modified electrode demonstrated fast response to glucose, along with high sensitivity and excellent selectivity. Based on these good results, the Mn₂O₃-Ag based composites were proved to be a promising biosensing platform for the construction of glucose biosensor.
