Surface-enhanced Raman scattering analysis of etheno adducts of adenine
We report surface-enhanced Raman spectroscopy (SERS) detection and analysis of several etheno adducts formed from the metabolism of vinyl chloride: 1,N6-ethenoadenine, 1,N6-ethenoadenosine, and 1,N6-etheno-2′-deoxyadenosine. Spectra of the etheno adducts are compared with unmodified adenine and 2′-deoxyadenosine. Chemical group assignments are made for the SERS peaks of these adducts and the limit at which SERS can detect the adducts is assessed. These assignments are compared with SERS analyses of nucleotides and nucleosides. © 1993.
