This work presents the main criteria to be considered when Surface Enhancement Raman Scattering substrate is used to detect low molecules concentrations. A comparison between hydrophilic and hydrophobic substrates is presented.
SummaryActually, studies about Surface Enhancement Raman Scattering (SERS) are taking more and more importance in areas like biomedicine, toxicology, pesticide on food and water contamination. The use of SERS substrates is a powerful tool to have standard enhancement factor to all the samples under measurement.
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.
