A rapid (2 h) organic solvent-based approach was developed to extract silver nanoparticles (AgNPs) from spinach leaves. The extracted AgNPs were enriched on a filter membrane and quantified by a surface enhanced Raman spectroscopic (SERS) mapping technique. The lowest detectable concentration of AgNPs was 1 ng mL⁻¹ and the accuracy was 74–113%.

快速有机溶剂萃取与表面增强拉曼光谱图联用，可对植物叶片中叶面施用的银纳米颗粒进行超灵敏定量

开发了一种基于有机溶剂的快速（2小时）方法来从菠菜叶中提取银纳米颗粒（AgNP）。提取的AgNPs在滤膜上富集，并通过表面增强拉曼光谱（SERS）定位技术进行定量。AgNPs的最低可检测浓度为1 ng mL ^-1，准确度为74–113％。
