Abstract
dc:description.abstract<p>The highly porous Mn<sub>2</sub>O<sub>3</sub>-Ag nanofibers were fabricated by a facile two-step procedure (electrospinning and calcination) and then employed as the immobilization matrix for glucose oxidase (GOD) to construct an amperometric glucose biosensor. A notable enhancement of direct electron transfer between GOD and the electrode is observed at the Mn<sub>2</sub>O<sub>3</sub>-Ag-GOD modified electrode with a fast electron transfer rate constant. The biosensor also shows fast response to glucose, high sensitivity (40.60 μA×mM<sup>-1</sup>×cm<sup>-2</sup>), low detection limit (1.73 µM at S/N=3), low <em>K</em><sub>m,app </sub>value and excellent selectivity. These results indicate that the novel Mn<sub>2</sub>O<sub>3</sub>-Ag nanfibers-GOD composite has great potential application in oxygen-reduction-based glucose biosensing.</p>
