A novel DNA assay is demonstrated which relies on the production of a surface enhanced resonance Raman scattering (SERS) signal following sequence specific hybridisation and enzyme hydrolysis. This method achieves high sensitivity and specificity that can be applied to the detection of unlabelled duplex DNA and is the first step towards a SERS based signal amplification approach.
