Raman reveals DNA in action

Abstract:
Researchers at the University of Strathclyde, UK, have been able to use Raman spectroscopy to observe strands of DNA pairing up and falling apart by attaching them to silver nanoparticles.

Surface enhanced resonance Raman scattering (SERRS) provides a vibrational spectrum of a molecule by measuring the difference in energy of the scattered light from that of incident light. The intensity of the scattering is magnified by adsorbing the target molecule onto a roughened metal surface such as silver or gold nanoparticles. A further enhancement results if the nanoparticles aggregate and the adsorbed molecule contains a chromophore with an electronic transition coincident with the excitation wavelength.
