摘要

介绍了基于超薄氧化铝模板(ultra-thin alumina mask, UTAM)制备的金属银纳米点阵表面增强拉曼散射(surface-enhanced Raman scattering, SERS)活性基底用于葡萄糖的高灵敏检测方法. 以UTAM为模板, 采用真空镀膜制备了大面积高度有序的银纳米点阵活性基底. 该基底的表面经过预处理, 吸附了一层癸硫醇/巯基己醇自组装分子层, 可用于检测葡萄糖. 研究结果表明, 该基底使葡萄糖分子的表面拉曼增强信号得到极大增强, 且增强信号均一稳定、检测灵敏, 特征峰的强度相对标准偏差小于10%. 该制备方法具有易操作、成本低的特点.

Abstract

A highly sensitive method for detecting glucose using Ag nanoparticle arrays surface-enhanced Raman scattering (SERS) active substrates based on the ultra-thin alumina mask (UTAM) was reported. The large-area highly ordered Ag nanoparticle arrays active substrates were fabricated using thermal evaporation with UTAM as a shadow mask in vacuum. The surface of active substrates can adsorb a layer of decanethiol/mercaptohexanol (DT/MH) self-assembled monolayers (SAM) through the surface pretreatment. Therefore the active substrates can be used for detecting glucose molecules. SERS measurement results of the active substrate with glucose molecules as probe molecules show strong SERS performance, and the enhanced signal is uniform and stable. The relative standard deviation (RSD) of the characteristic peak intensity is less than 10%. This preparation method has the advantages of simple operation and low cost.
