Raman laser

We use Raman spectroscopy as an advanced characterisation tool for nanotechnologies in chemistry, biochemistry, materials science, and physics.

Surface-enhanced Raman spectroscopy (SERS), is a technique which enhances the Raman scattering effect by observing molecules after their adsorption onto rough metal surfaces or metallic colloids. The enhancement can be as much as a factor of 108-109, which increases sensitivity enough to allow single molecules to be detected. We conduct experiments to find substrates which combine high SERS enhancements with good reproducibility and research ways to avoid or control SERS fluctuations. 

The Raman Lab is a research facility run jointly by the School of Chemical and Physical Sciences (SCPS) and the MacDiarmid Institute for Advanced Materials and Nanotechnology.

Our facilities are made available to researchers in both these institutions as well as to external clients.

Research Collaborations

Our group has strong links with Imperial College in London, with both the physics Department (Blackett Laboratory) and the Department of Electrical and Electronic Engineering. We also collaborate with groups in France and Switzerland.
