Our work has focussed on developing surfaces that kill microbes. In particular we are looking at reducing hospital acquired infection by making surfaces that kill bacteria such as e-coli and MRSa by the action of light. We have just started an MRC funded project that looks to provide a solution to catheter acquired infections. These infections make up over 80% of all hospital acquired infections. We have shown that we can develop surfces that kill bacteria and more importantly stop biofilm formation. We are focsssing on urinary catheters at present.
We have a seperate research theme- that of using sunlight to split water into hydrogen and oxygen. This could, if perfected, provide virtually limitless hydrogen for use as a fuel. We have made a working prototype that demonstrates the principle- the first such prototype outside of Japan. We have also shown that there is a key thickness of one of the components of the photodiode that when optimised enables up to a six fold enhancement in hydrogen production.
