A Miniaturized Electrochemical SERS Chip with 3D Nanoporous Gold Interface for Qualitative and Quantitative Analysis of Organic Pollutants and their Oxidation Intermediates.

ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs) and organophosphorus pesticides (OPPs) are typical pollutants characterized by a wide variety of types, difficulty in degradation, and significant differences in mutagenic and carcinogenic toxicity. However, due to their distinct physicochemical properties, it remains challenging to simultaneously analyze PAHs and OPPs under real environmental conditions within the same simplified detection systems and accurately assess their oxidation-reduction processes. In this study, electrochemical surface-enhanced Raman scattering (EC-SERS), utilizing a microfluidic chip of self-made 3D nanoporous Au loaded with Ag nanoparticles, is employed to analyze PAHs and OPPs in the environment and investigate their oxidation-reduction processes, which displayed excellen
