中文摘要：

采用无氰化学镀金法在聚二甲基硅氧烷（PDMS）印章表面镀金,通过微接触印刷技术将PDMS印章上的Au纳米粒子（AuNPs）分别转移到氧化铟锡（ITO）透明导电膜玻璃,修饰了（3-巯基丙基）三甲氧基硅烷（MPTMS）的ITO基底（MPTMS/ITO）和表面电镀了铜膜的ITO（Cu/ITO）表面上,同时形成有序的结构或者图案.通过场发射扫描电镜（FE-SEM）,原子力显微镜（AFM）和显微共聚焦激光拉曼光谱仪等对实验结果进行表征.结果表明,该转移AuNPs的方法对基底表面特性并无特殊要求,是一种简单、快速、无污染、低成本的AuNPs转移技术,而且转移了AuNPs的ITO基底具有表面增强拉曼光谱（SERS）活性,有望在SERS中有所应用.

英文摘要：

A poly（dimethylsiloxane） （PDMS） stamp was electrolessly plated using a cyanide-free solution.Gold nanoparticles （AuNPs） were transferred from the PDMS stamp to indium tin oxide （ITO）,（3mercaptopropyl） trimethoxysilane modified ITO （MPTMS/ITO）,and an ITO substrate electrodeposited with a thin copper film （Cu/ITO）.AuNPs formed well-ordered structures which were characterized by field emission scanning electron microscopy （FE-SEM）,atomic force microscopy （AFM）,and Raman spectroscopy.Microcontact printing allowed thin AuNPs films to be directly transferred from PDMS to substrate,so is a simple,fast,cheap and environmentally-friendly technique.AuNPs patterned on the ITO substrate exhibited surface-enhanced Raman spectroscopy （SERS） activity which will be investigated in subsequent studies.
