Researchers from the UK and Greece have developed a new way to enhance SERS (Surface-enhanced Raman scattering) signals. SERS is a powerful way to identify molecules at very low concentrations – a technique that has proven very useful in forensics, medical diagnostics and identifying new drugs.

The researchers used Graphene as a substrate for SERS, and they say it performs better then current solutions - and can help us better understand SERS physics.
