Advances in the Detection of Common Mycotoxins in Foods by Surface-Enhanced Raman Spectroscopy

Abstract

As a novel and rapid detection technique, surface-enhanced Raman spectroscopy (SERS) has many advantages such as simple sample pretreatment, rich spectral information, high sensitivity, rapidity, easy operation, and immunity to interference from water molecules. Hence, SERS has been considered a powerful tool and a research hotspot for food safety rapid detection. This article reviews the development, enhancement mechanism, and detection modes of SERS, and summarizes the latest progress in the detection of common mycotoxins in foods by SERS. Moreover, its problems to be solved and future trends are discussed. It is hoped that this review can provide a reference for future research and development of SERS technology for rapid detection of mycotoxins.
