Abstract
Melamine is harmful to human health. Excessive use will seriously endanger human health. Therefore, it is necessary to detect the content of melamine in food. In this study, melamine was taken as the research object, and the Raman peaks of melamine were analyzed by density functional theory and compared with the actual samples. After that, melamine was detected by surface-enhanced Raman spectroscopy using gold nanoparticles and silver nanoparticles as substrates respectively. The experimental results showed that the Raman signal of silver nanoparticles as substrates was better than that of gold nanoparticles, therefore, the method has the advantages of simple operation and short process time, and provides a method for detecting melamine.
