There is a pressing need for the development of enhanced electrochemical sensor systems of high fidelity, particularly for healthcare and energy applications. This talk will outline two aspects of enhancement; the development and characterisation of novel enhanced microelectrode and nanoelectrode systems and the design and functionalisation of electrodes with selected materials for specific sensing and analysis. Novel single electrode and multielectrode devices will be presented which have been designed and produced through microfabrication, showing both their predicted theoretical and established experimental response. Developments in two application areas will then be presented, where specific materials functionalisation has been carried out to produce electrodes tailored to selective sensing. In the first application, progress towards enhanced biosensors which detect disease-relevant markers from real-world biological matrices with enhanced rapidity and sensitivity will be outlined. The second application area addressed will be the development of sensing and analysis systems suited to measurement in the hostile environment of molten salts. Molten salts are an attractive medium for chemical and electrochemical processing with potential applications in pyrochemical nuclear fuel reprocessing, metal refining, molten salt batteries and electric power cells and as a result there is demand for molten salt-compatible sensing technologies. Work to develop suitable sensing technologies will be presented and discussed.
