采用表面分子印迹技术在银微球表面包覆一层印迹聚合物（ Ag＠MIPs ）。利用扫描电子显微镜（SEM）、透射电子显微镜（TEM）及X射线衍射仪（XRD）等手段对所制备Ag＠MIPs进行表征。对Ag＠MIPs的SERS性能研究表明，Ag＠MIPs的SERS强度明显高于银微球，且对罗丹明B（ RhB）的检测限可达10－13 mol／L，Ag＠MIPs的竞争吸附性结果表明Ag＠MIPs对RhB具有优越的选择特异性。%Core-shell silver-molecularly imprinted polymers ( Ag@MIPs) was synthesized by surface molecular imprinting technique .SEM,TEM and XRD were applied to characterize the as-prepared Ag@MIPs.The SERS signals of RhB indicated that Ag@MIPs have higher SERS activity than that of bare Ag particles , and the detection limit of RhB was 10 -11 mol/L.The results of competitive adsorption of Ag@MIPs showed that the Ag@MIPs possess good selectivity for RhB .
