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.

Abstract:

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), (3- mercaptopropyl) 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.

Key words: Microcontact printing, Gold nanoparticle, Transfer, Poly(dimethylsiloxane), Surfaceenhanced Raman spectroscopy
