Rapid and sensitive surface‐enhanced Raman spectroscopy (SERS) method combined with gold nanoparticles for determination of paraquat in apple juice

Abstract

This work showed that SERS combined with gold nanoparticles could determine paraquat in apple juice. As a simple, rapid and ultrasensitive method, it has great practical potential for detection of other contaminants in a variety of foods. © 2018 Society of Chemical Industry.
