Raman spectroscopy is known as a powerful materials characterisation method that is complementary to infrared spectroscopy. For conventional Raman spectroscopic measurements, a monochromatic laser light is focused on the sample where Raman scattering occurs. The Raman light is collected from the focal point where the spatially resolved spectral information is analysed. In our research we use FT-Raman spectroscopy, confocal Raman microscopy and tip-enhanced Raman spectroscopy (TERS), we have obtained some of the first TERS chemical images at nanoscale for non-conductive samples (see articles in Nanotechnology in TERS section below). This TERS research has been supported by our ERC Advanced Grant (ERC grant 227950): "Enhancing microfabricated devices with chemical imaging for novel chemical technology"
