摘　　要：研究了Au纳米粒子-细菌纤维素复合纤维在生物传感器、微导线、催化领域的应用。复合纤维具有网络状结构,可高效捕捉、担载过氧化氢酶,制成的H2O2生物传感电极灵敏度达到1μM,线性区间为1μM^1mM,高于大多数文献的报道值。电导性测试表明复合纤维的阻抗较大,对微电流表现出了较好的灵敏度。另外复合纤维可用作组建连续催化装置,待催化流体流经复合纤维网络时发生催化反应。The application of Au-BC composite nanofibers in biosensor, electronics, catalysis fields was investigated. Au-BC nanofibers can catch enzyme effectively benefiting from their network structure, and form H2O2 biosensor electordes which shows excellent sensor performance. Besides, Au-BC composite nanofibers display well sensitivity to micro-current, and could be used as microfuses. The network nanofibers could be further used as catalyst in a flowing catalysis system for the continuous reaction of flowing liquid.
