Fourier-transform infrared (FT-IR), Raman (RS),respectively. The analysis of the SERS spectra shows that HMB interacts with the silver surface mainly through the -COO − , hydroxyl, and -CH 2 -groups, whereas L-carnitine binds to the surface via -COO − and -N + (CH 3 ) 3 which is rarely enhanced at pH = 8.3. On the other hand, it seems that creatine binds weakly to the silver surface mainly by -NH 2 , and C O from the -COO − group.
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.
