Abstract

The diagnostics and monitoring of trace amounts of technogenic and biological substances are becoming increasingly relevant in the modern world. One approach to solving them is surface-enhanced Raman scattering (SERS). In this work, we propose a variant of manufacturing SERS substrates in the form of dendritic silver nanostructures with the spatial modulation of wettability, which ensures concentration of the analyte upon drying. The proposed technical solutions are tested using rhodamine 6G and 4-aminothiophenol as analytes. The SERS surfaces used for this purpose provide a high measurement sensitivity and are easy and affordable to manufacture.

用于液体 SERS 诊断的树枝状银结构

痕量技术和生物物质的诊断和监测在现代社会中变得越来越重要。解决这些问题的方法之一是表面增强拉曼散射（SERS）。在这项工作中，我们提出了一种以树枝状银纳米结构形式制造 SERS 基底的变体，它具有空间润湿性调制功能，可确保干燥后分析物的浓度。我们使用罗丹明 6G 和 4-氨基苯硫酚作为分析物对所提出的技术方案进行了测试。用于此目的的 SERS 表面具有很高的测量灵敏度，而且易于制造，成本低廉。
