Abstract

Directed deposition of silver on the surface of single, soluble enzyme molecules was made possible by controlled conjugation of new silver-reducing moieties to the surface of the enzyme molecule and their reaction with silver ions. Molecular enzyme-silver hybrids carrying low or high crystalline silver deposited on their surface were obtained, retaining their solubility and enzymatic activity. The feasibility of ``wiring'' of the active site of glucose oxidase-silver hybrid thus obtained to platinum electrode was readily demonstrated enabling glucose determination in the absence of oxygen.
