Abstract:Traditional foodborne bacterial detection methods have limitations, driving the need for advanced techniques like surface-enhanced Raman spectroscopy (SERS), known for its high sensitivity, specificity, and nondestructive analysis in food safety. However, SERS faces challenges regarding substrate sensitivity and complex sample preparation. This study presents an innovative photo-driven method for synthesizing surfactant-free anisotropic gold nanoparticles for SERS applications. These gold nanostars, with uniqu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
