Rapid Organic Solvent Extraction Coupled with Surface Enhanced Raman Spectroscopic Mapping for Ultrasensitive Quantification of Foliarly Applied Silver Nanoparticles in Plant Leaves

Abstract

A rapid (2h) 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 and the accuracy was 74-113%.
