In this work, surface enhanced Raman scattering (SERS) spectra of aspirin and ibuprofen molecules adsorbed on the surface of silver nets sputtered on porous silicon were collected and analyzed. The bands in the SERS-spectra were correlated in accordance with the type of molecular vibration. Predominantly chemical adsorption of the indicated drugs on the SERS-active substrate through oxygen was observed. It was established that the Raman spectroscopy combined with the SERS-active silver nets makes it possible to detect the aspirin and ibuprofen at 10-6 M concentration.
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.
