My research interest is the surface modification of graphite powder, glassy carbon microspheres and carbon nanotubes with a range of aromatic organic molecules, biological molecules such as cysteine and metal nanoparticles. The resulting materials can be characterized using voltammetric techniques, by immobilizing the modified carbon material onto the surface of a suitable substrate. The voltammetric characterization of these novel materials is frequently carried out in conjunction with other surface analysis techniques, where appropriate, such as X-ray photoelectron spectroscopy and scanning electron microscopy.
