摘要：

Quantum size effect was strongly supported by the experiment on correlation between size of gold nanoparticles (below 10 nm) and activity of glucose oxidase attached to them. The attractive enhancement effect of gold nanoparticles on the activity of glucose oxidase was then satisfactorily explained. In this experiment, 2 nm and 6 nm (average diameter) particles were obtained on monolayer matrix. The 2 nm particles proved to be much more able to increase the activity of glucose oxidase.
