摘要

以聚二烯丙基二甲基氯化铵（PDDA）为阳离子聚电解质

以乙醇氧化酶（AOD）为带负电的生物分子

结合多壁碳纳米管（MWCNTs）

层层自组装（layer-by-layer）制备聚烯丙胺/聚磺化乙烯硫酸盐乙醇（PAA/PVS）3抗干扰膜修饰Pt电极

在此基础上将PDDA与AOD交替组装在修饰好的电极上

构建了电流型乙醇生物传感器。实验结果表明:MWCNTs的引入使电极对H2O2的催化电流明显增大

制成的酶电极可以有效控制酶量的使用

酶膜组装层数为6时最优

对乙醇的灵敏度为2.913μA/mol/L

在2×10-4

×10-3mol/L浓度范围内呈良好线性关系

检出限为1.52×10-5mol/L（S/N=3）

并且传感器具有良好的抗干扰能力和稳定性。

Abstract

A novel ethanol biosensor of Pt-（PAA/PVS）3-（MWCNTs-PDDA/AOD） 6with enhanced sensibility

excellent anti-interfence property is fabricated.Poly（allylamine）/poly（potassium vinyl sulfate）（PAA/PVS） multiple film is self-assembled on the surface of Pt electrode based on layer-by-layer deposition to enhance the anti-interference ability.Poly（dially dimethyl ammonium） chloride（PDDA） is used as cationic polyelectrolyte and multi-walled carbon nanotubes（MWCNTs） is conformed to be useful in ethanol biosensors fabrication via comparing the biosensors fabricated with and without MWCNTs.It shows a linear response to ethanol in the range of

2.0×10-4

.0×10-3mol/L

high sensibility of 2.913 μA/（mmol/L）

low detection limit of 1.52 ×10-5mol/L（S/N=3）

and good suppression of interference ability and stability.
