Ag colloid-ethanethiol films: spacer-modified substrates for surface-enhanced resonance Raman scattering spectroscopy of chromophoric molecules

Abstrakt

Glass-deposited Ag colloid-ethanethiol films were prepared and employed as spacer-modified substrates for obtaining SERRS spectra of the native, unperturbed forms of biologically important molecules, -carotene and tetrapyridylporphine.
