"Carbon based electrochemical sensors for the detection of species in complex environments"
(Chemistry, Physics, Engineering)
Electrochemistry represents a low cost, potentially non-invasive means of sensing the solution environment, such as trace species in pharmaceutical processing e.g. potential genotoxic impurities (PGIs), process waters and biological environments such as neurotransmitters. Carbon electrodes (sp3 and sp2 hybridised) are particularly attractive electrodes due to their biocompatibility and low cost. However different forms of carbon show different degrees of catalytically activity towards different target analytes. I will design, using a “bottom up” approach, new electrodes for different trace species detection,which can also be integrated into non-perturbative on-line flow-detection systems. Key objectives are to reduce analysis times, lower costs and improve on current detection levels.
