Surface-Enhanced Raman Spectroscopy Method for Sensitive Detection of Antibiotic Residues by Layer-Optimized Multilayer Nanoparticle Film Structures
Surface-enhanced Raman scattering (SERS) has been widely applied to food safety screening owing to its high sensitivity and fingerprint recognition. However, SERS faces challenges in practical applications related to the precise control of the number of hot spots and the determination of how many of them actually contr...
