用UV-Vis光谱、荧光光谱和电泳等方法考察了半胱氨酸(Cys)同银(I)离子间的相互作用以及在微乳液体系中制备氨基酸-银固态物种,并用扫描电子显微镜(SEM)和EDS能谱进行了结构分析和表征.研究了介质的pH,各组分浓度,包括半胱氨酸、银(I)离子、甲醛、十二烷基硫酸钠(SDS)和Na_2B_4O_4以及温度、光照度和光照时间等对反应的影响.结果表明,半胱氨酸(Cys)与银(I)离子作用的最佳条件是pH=7.39左右,Cys浓度为2.4mmol·L~(-1),AS(NH_3)_2~+浓度为1.2 mmol·L~(-1),Na_2B_4O_7浓度为3.0 mmol·L~(-1),SDS浓度为0.4%,HCHO浓度为0.008%,反应时间为90 min,光照度>600 Lux.制备的氨基酸-银固态物种,各成分的理论含量与实测结果基本相吻合,其形貌主要为三棱柱和四面体,微粒粒径在1～100 μm之同.
