摘要：

The preparation and characterization of gold nanoparticles (similar to 6 nm in diameter) modified with mono-6-thio-beta-cyclodextrin (II) is described. The resulting monolayer-protected gold nanoparticles are water-soluble and more stable. The concentration of II plays a crucial role for the distribution of the modified nanoparticles. When the ratio of concentration of II to HAuCl4,[II]/[HAuCl4] >= 0.93, a stable gold nanoparticle with uniform distribution and diameter of 6.0 +/- 0.9 nm will be obtained. The recognition of modified gold nanoparticles to organic guest molecule is researched. The modified gold nanoparticles can make the electrochemical reduction current of nitrobenzene decrease and can be self-assembled in three-dimensional to form spherical clusters with ligand of methylene green.
