Surface-enhanced Raman spectroscopy facilitates the detection of multiple metabolic modulators

Metabolic regulators can improve the athletic ability of athletes by regulating body metabolism, but it is not conducive to fair competition, so it is listed as a prohibited substance. At the same time, the State General Administration of Sport ordered major event organizers to test food for food-borne stimulants. Surface-enhanced Raman scattering (SERS) spectroscopy has been widely used because of its excellent sensitivity and strong spectral characteristics. Based on the available information, SERS spectrum data of metabolic regulators in food-related fields were lacking. In this study, we used gold dodecahedron nanoparticles as SERS active substrate and successfully captured the characteristic peaks of 6 metabolic regulatory factors. A low cost and stable SERS detection technique for detecting trimetazidine in milk samples with good recovery rate was proposed. Therefore, this method can not only protect the food safety of large-scale sports events, but also have broad application prospects in the food field.
