Overcoming Detection Challenges of 2,4‑D Herbicides via SERS through a Simple Modification of Citrate-Reduced Silver Nanoparticles.

ABSTRACT: The difficulty in detecting certain pesticides at low concentrations in aqueous media made it necessary to search for new strategies to facilitate the detection of these contaminants. In this context, surface-enhanced Raman scattering (SERS) is a promising technique capable of carrying out the detection of hard-to-detect molecules. A pesticide called 2,4-dichlorophenoxyacetic acid (2,4-D) is within the group of these molecules that is difficult to detect. Currently, 2,4-D is recognized as one of the main herbicides used around the world, which has attracted the attention of researchers. This study investigates the synthesis of silver nanoparticles using a modified method based on citrate reduction. Three different colloids, AgCit1.0, AgCit0.50, and AgCit0.25, were synthesized with varying
