The paper describes the preparation of advanced Ag and Au nanostructures via thermal deposition on three gradual grades of microabrasive processed (100) SiO₂ substrates and the investigation of their morphology and optical properties. The quartz substrates were manually dry scratched in advance with three grades (0.1, 0.5, or 1 μm) of diamond supper‐abrasive slurry coated on high precision polyester film. The deposition of Ag or Au was first applied, and then the films were laser annealed. The as‐prepared nanostructures were used for surface‐enhanced Raman spectroscopy analyses of neonicotinoid insecticide Mospilan 20 SP, which contains acetamiprid, in quantities much smaller than that usually applied in the agricultural medicine. The efficiency of the fabricated advanced structures was studied using the finite difference time domain method. The limit of detection of Mospilan 20 SP (acetamiprid) was estimated to be about 40 nM, and the enhancement factor of polished quartz was about 6.6 × 10³. This study of harmful pollutant in small or residue quantities is very important in order to preserve the honey bees' health and thus for conservation of the environment.

Ag和Au纳米结构用于Mospilan 20 SP（对乙酰氨基苯甲酸）的表面增强拉曼光谱

本文介绍了通过在三个渐进等级的微磨料加工的（100）SiO ₂上热沉积制备先进的Ag和Au纳米结构的方法基质及其形态和光学性质的研究。预先用三种等级（0.1、0.5或1μm）的金刚石超磨料浆在高精度聚酯薄膜上进行干燥，以手动方式刮擦石英基板。首先进行Ag或Au的沉积，然后对膜进行激光退火。所制备的纳米结构用于新烟碱类杀虫剂Mospilan 20 SP的表面增强拉曼光谱分析，其中Mospilan 20 SP含有乙酰胺，其数量比通常在农业医学中使用的数量少得多。使用时域有限差分法研究了制造的先进结构的效率。Mospilan 20 SP（扑热息痛）的检出限估计约为40 nM，抛光石英的增强因子约为6.6×10³。为了保护蜜蜂的健康并保护环境，对少量或残留有害污染物的研究非常重要。
