The Interface Analytics department is concerned with molecular processes at interfaces and on surfaces, such as molecule bonding on surfaces or the formation and properties of nanostructures. The work focuses on biological and biomedical applications. Our remit is to investigate in detail materials, structures and surfaces that consist of a mixture of organic molecules and inorganic materials or that interact with biomolecules, and whose special properties could, for example, make them suitable for biosensors.
We deploy different methods of optical spectroscopy to investigate these materials and surfaces. These methods enable us to analyse the structures in situ without having to destroy them. Our experiments with Raman spectroscopy, ellipsometry, reflectance anisotropy spectroscopy (RAS) and atomic absorption spectrometry use quite a broad spectrum of light - from far infrared (IR) to visible light through to vacuum ultraviolet radiation (VUV).
