Abstract Advanced silver and gold nanostructures were fabricated on alumina ceramic by thermal deposition technique. They were applied as active substrates for surface-enhanced Raman spectroscopy analyses of the neonicotinoid insecticides Nuprid 200 SP and Warrant 700 WG, both containing imidacloprid, in quantities much smaller than usually applied in the agricultural medicine. The efficiency of the fabricated structures was simulated by finite difference time domain (FDTD) method. The limit of detection of imidacloprid was estimated to be about ≈0.05 mM. The detection of small amounts or residue of harmful pollutants was forwarded to bearing on the environment and especially on the honey bees’ health.

金银纳米结构辅助新烟碱类杀虫剂吡虫啉的表面增强拉曼光谱

摘要 采用热沉积技术在氧化铝陶瓷上制备了先进的银和金纳米结构。它们被用作活性基质，用于新烟碱类杀虫剂 Nuprid 200 SP 和 Warrant 700 WG 的表面增强拉曼光谱分析，这两种杀虫剂均含有吡虫啉，其数量远小于通常用于农业药物的数量。通过有限差分时域（FDTD）方法模拟制造结构的效率。吡虫啉的检测限估计约为 ≈0.05 mM。有害污染物的少量或残留检测被转发到对环境，特别是对蜜蜂健康的影响。
