Surface enhanced raman scattering (SERS) of nucleic acid bases adsorbed on silver colloids

The surface enhanced Raman spectra of the nucleic acid bases guanine, adenine, thymine and cytosine adsorbed on small particles of colloidal silver have been recorded in the spectral range of 100 to 1700 cm −1. Prominent SERS bands for these bases are the ring-breathing modes at 653 cm −1 in guanine...

Description
Summary:The surface enhanced Raman spectra of the nucleic acid bases guanine, adenine, thymine and cytosine adsorbed on small particles of colloidal silver have been recorded in the spectral range of 100 to 1700 cm −1. Prominent SERS bands for these bases are the ring-breathing modes at 653 cm −1 in guanine, 728 cm −1 in adenine, 789 cm −1 in thymine and 797 cm −1 in cytosine. This new spectroscopic method provides a powerful technique for in situ investigations of adsorbed nucleic acid components of a rather dilute aqueous solution (10 −6 M).
