摘要: 基于分子间静电相互作用力,将锇-聚乙烯吡啶复合物(PVP-Os)与辣根过氧化物酶(HRP)交替沉积于固体基质表面,制得了包含生物成分的分子多层膜.膜层间的聚合物分子起到了粘接与导电的双重作用.用紫外-可见光谱法跟踪了石英基片上的组装过程,研究了多层膜电极对过氧化氢的电催化还原性能,并描述了多层膜电化学行为.

Abstract: We prepared a new kind of multilayer films based on ionic self-assembly technique by successive alternating deposition of positively charged polycation bearing Os complex(PVP-Os) and horseradish peroxidase(HRP) on the surface modified of gold electrode to study the electrochmical behavior and quartz slides to monitor the assembly process by ultraviolet-visible spectroscopy. The electrochemical behavior of the enzyme electrode showed that the multilayer films were stable, electroactive, the mediator PVP-Os as electron shuttle was able to transfer electrons successfully between the active center of the immobilized HRPand the electrode surface.

Key words: Poly(4-vinylpyridine) complex of Osmium, Horseradish peroxidase, Molecular multilayer, Electrical catalysis, Self-assembly
