Independent analysis of these species is problematic and analytical difficulties relating to instrumental selectivity and sensitivity need to be overcome. This thesis describes the work carried out on the development and characterisation of a range of systems that could be used to facilitate thiol detection, ideally at the point-of-care, focussing largely on electrochemical techniques. Silver-thiol interactions were studied as a route to assist the sample processing. Here a novel controlled silver release mechanism was assessed.

The development of unique molecular imprinted polymers was attempted.
