Our research focuses on the analytical detection of biological events on surfaces. Observing the effect of small molecules on nucleic acids and cells is of particular interest. Nanoparticles conjugated with biomolecules enable us to monitor the recognition events using electrochemical (voltammetry) and spectroscopic (localized surface plasmon resonance) techniques. The modification of carbon, gold and mercury surfaces with nanoparticles and biomolecules is carried out to obtain innovative biosensing schemes. Our research involves aspects of diverse disciplines ranging from surface science, electronics and molecular biology to materials science and nanotechnology.
