The spectral signatures of two samples of single stranded DNA were analyzed using Raman spectroscopy. One was a 15-base thymine sequence and the other was an aptamer containing thymine and guanine bases. A Surfaceenhanced Raman spectroscopy (SERS) substrate was used to enhance the signal to detectable levels. Many vibrational modes corresponding to bonds within DNA were detected.
