Abstract In this study, gold nanoparticles (GNPs) were successfully fabricated via a polymer-templating method and applied for surface-enhanced Raman scattering (SERS) enhancement. The block copolymer, poly(ethylene glycol)-block-poly(styrene-alt-maleic anhydride) (PEG-b-PSM) modified with thiol groups, was used to prepare GNPs. The results indicated that the polymer facilitated GNPs to form an assembly without aggregation; thus, the distance between adjacent GNPs could be ideal for SERS application. Furthermore, when deposited onto indium tin oxide (ITO) thin film, GNPs prepared via the polymer-templating method showed more ordered behavior than GNPs prepared by using a conventional method, that is, citrate reduction.

使用硫醇官能化嵌段共聚物 PEG-b-PSMT 通过聚合物模板技术制备金纳米粒子及其在 SERS 增强中的应用

摘要 在这项研究中，金纳米粒子 (GNPs) 通过聚合物模板方法成功制备并应用于表面增强拉曼散射 (SERS) 增强。用硫醇基团改性的嵌段共聚物聚（乙二醇）-嵌段-聚（苯乙烯-alt-马来酸酐）（PEG-b-PSM）用于制备 GNP。结果表明，聚合物促进了 GNPs 形成无聚集的组装体；因此，相邻 GNP 之间的距离可能是 SERS 应用的理想选择。此外，当沉积在氧化铟锡 (ITO) 薄膜上时，通过聚合物模板法制备的 GNP 表现出比使用传统方法制备的 GNP 更有序的行为，即柠檬酸盐还原。
