Development of Silver Nanowires Based Highly Sensitive Amperometric Glucose Biosensor

The fabrication of a highly sensitive ampero- metric glucose biosensor based on silver nanowires (AgNWs) is presented. The electrochemical behavior of glassy carbon electrode modified by Ag NWs exhibits re- markable catalytic performance towards hydrogen perox- ide (H2O2) and glucose detection. The biosensor could detect glucose in the linear range from 0.005 mM to 10 mM, with a detection limit of 50 m M( S/N = 3). The glucose biosensor shows high and reproducible sensitivity of 175.49 m Ac m � 2 mM and good stability. In addition, the biosensor exhibits a good anti-interference ability and fa- vorable stability over relatively long-term storage (more than 21 days).
