This project aims to develop new antimicrobials to address the rise of drug-resistant infections and resilient bacterial communities called biofilms. We aim to break new ground in our fundamental knowledge of antimicrobial mechanisms and exploit this understanding by fusing cellular/molecular microbiology and synthetic chemistry approaches. We seek to gain an in-depth understanding of how nitroxides induce bacterial biofilm dispersal, which is critical for the discovery of anti-biofilm molecules that do not fail due to resistance development. These breakthroughs should induce a step-change in our ability to reduce the occurrence of biofilm-related infection in fields ranging from medical and veterinary to biotechnology and agriculture.Read moreRead less

This project aims to synthesise the first examples of advanced biological imaging agents that can reversibly respond to the oxidative status of living cells. Novel mitochondrially-targeted, fluorescent probes will be derived from several well-established families of biological dyes through the introduction of a stable free radical within the parent structure. The design of the new imaging agents aims to both enhance retention in, and restrict the fluorescence response to, the mitochondria so that changes in oxidation and reduction can be monitored. The probes will provide an innovative new means to assess reactive species and associated oxidative stress, thus delivering a new methodology to aid research into mitochondrial chemical biology.Read moreRead less
Designer solvents to control reaction outcome. This project aims to control outcomes of chemical reactions using specifically designed ionic liquids as solvents. Ionic liquids are distinct from molecular solvents and are underused due to the limited understanding of their effects on chemical processes. We are developing a predictive framework to explain such effects and this project aims to exploit this new knowledge, using both new and rarely applied ionic liquids to control reaction outcomes. ....Designer solvents to control reaction outcome. This project aims to control outcomes of chemical reactions using specifically designed ionic liquids as solvents. Ionic liquids are distinct from molecular solvents and are underused due to the limited understanding of their effects on chemical processes. We are developing a predictive framework to explain such effects and this project aims to exploit this new knowledge, using both new and rarely applied ionic liquids to control reaction outcomes. The significance lies in the ability to optimise reaction outcomes without the need for solvent screening. The innovation lies in the measurement of microscopic interactions between solvent and reagents, and the use of these interactions to affect a given process.Read moreRead less
