Findings from University of Evora Provide New Insights into Sulfanilamides (Adsorption of sulfamethoxazole molecule on silver colloids: A joint SERS and DFT study)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Sulfanilamides have been published. According to news reporting originating in Evora, Portugal, by NewsRx journalists, research stated, "FTIR/ATR, FT-Raman and surface-enhanced Raman scattering (SERS) spectroscopic techniques, as well as density functional theory (DFT) calculations were used in order to characterize the sulfamethoxazole (SMX) molecule."

The news reporters obtained a quote from the research from the University of Evora, "Particular emphasis was put on the adsorption geometry of the molecule to the silver colloidal nanoparticles surface. FTIR/ATR, FT-Raman, Raman aqueous solution and SEAS spectra of SMX were assigned based on DFT calculations with the hybrid B3LYP exchange-correlation functional, coupled with the standard 6-31G(d) basis set."

According to the news reporters, the research concluded: "Calculations performed on the SMX molecule adsorbed on a slab constructed to model the Ag(1 1 1) surface give quantitative results related to the geometry of the molecule in the vicinity of the silver surface."
