The effect of solvent environment toward optimization of SERS sensors for pesticides detection from chemical enhancement aspects
TL;DR: In this paper, a flower-shaped silver nanoparticle was used as a substrate to investigate the SERS effect of pesticide molecules under different treatment conditions, and it was demonstrated that the optimum pH values for test conditions are in the range of 6.66-11.11 due to the auxiliary of H + ions and undestroyed complete functional groups of ethion.
