| Description | We have contributed strongly to the development of monitoring electrochemical (redox) reactions by diverse spectroscopic methods. We have introduced a unique device (spectroelectrochemical cell) for probing redox reactions and improving detection limits of optically active compounds of importance in the fields of pharmaceutical research, DNA research, catalysis. We have developed novel spectroelectrochemical cells for far infrared region and for monitoring redox reactions of compounds attached (chemisorbed, self-assembled) on electrode surfaces by infrared spectroscopy at variable temperature. These method further expand the existing portfolio of spectroelectrochemical methods. Finally, we have introduced for the first time the highly interesting medium of ionic liquids to spectroelectrochemistry. Ionic liquids have played a significant role in working on the key target of the EPSRC project - studying gated electron transfer on a molecular level using a scanning tunnelling microscope (in collaboration with Prof. Richard Nichols in Liverpool). |
