For the first time ,AgBr organosol was obtained by using oleic acid to extract and modify the AgBr nanoparticles in hydrosol. And the optimum molar ratio of oleic acid to AgBr nanoparticles was found. AgBr nanoparticles, modified by oleic acid were mixed with MMA. After polymerization was carried out, the polymeric photochromic material was synthesized.

SERS labelled immunogold was then used as probe to detect the interaction between the Goat anti-rat IgG and silver substrate (which we will use it as the substrate for solid antibody). It is found from experiment that SERS labelled immunogold can be non-specifically adsorbed onto silver surface uniformly because of the strong interaction between the protein molecule and silver.

由于我们设想以银片为免疫检测中固相抗体的基底，所以论文中首先以SERS标记的免疫金溶胶为探针，讨论了抗体与银表面间的作用，实验中发现，SERS标记的免疫金溶胶可以通过抗体与银之间的作用较好的自组装于银表面，同时，银表面上可以测到很强的苯硫酚的SERS信号。
