Fighting slime with free radicals - new surface coatings for biofilm remediation. Bacterial biofilms are a major problem in a number of environmental, industrial and medical applications. They cause significant risks to human health and present an enormous economic burden to society. This project aims to develop smart polymeric coatings that will discourage bacterial attachment and ensure greater long term control over biofilm growth.

Bacterial biofilms are a major problem in a number of environmental, industrial and medical applications. They cause significant risks to human health and present an enormous economic burden to society. This project aims to develop smart polymeric coatings that will discourage bacterial attachment and ensure greater long term control over biofilm growth. These coatings represent a breakthrough in the field and will have a profound impact in many areas, including reducing infections related to medical implants and improving the efficiency of marine engineering systems.Read moreRead less
Eradicating bacterial biofilms with nitroxide-antimicrobial hybrids. 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 dis ....Eradicating bacterial biofilms with nitroxide-antimicrobial hybrids. 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
Computational tools for organic synthesis. This project aims to develop new computer modelling techniques with the ability to rapidly identify efficient synthetic routes to target molecules. The barrier heights, reaction energies, and product selectivities of the individual steps in a multi-step synthesis are key factors determining its overall efficiency, and are traditionally determined empirically. Innovative tools for predicting these properties through computer simulations are the expected ....Computational tools for organic synthesis. This project aims to develop new computer modelling techniques with the ability to rapidly identify efficient synthetic routes to target molecules. The barrier heights, reaction energies, and product selectivities of the individual steps in a multi-step synthesis are key factors determining its overall efficiency, and are traditionally determined empirically. Innovative tools for predicting these properties through computer simulations are the expected outcomes of this project. These tools are anticipated to enable target molecules to be accessed more efficiently, with less expenditure of laboratory resources and a lower environmental impact, thereby contributing to an agile and sustainable chemical industry.Read moreRead less
Opening Up Access to L-Sugars through a Synergy of Experiment and Theory. This project aims to address a major bottleneck in the science of carbohydrates by developing the first broad-scope synthetic routes to L-sugars. L-sugars are critical components of many biologically and commercially significant molecules, but knowledge of their functional roles is impeded by the fact that most L-sugars are expensive or difficult to make. This project expects to develop expeditious routes to L-sugars via a ....Opening Up Access to L-Sugars through a Synergy of Experiment and Theory. This project aims to address a major bottleneck in the science of carbohydrates by developing the first broad-scope synthetic routes to L-sugars. L-sugars are critical components of many biologically and commercially significant molecules, but knowledge of their functional roles is impeded by the fact that most L-sugars are expensive or difficult to make. This project expects to develop expeditious routes to L-sugars via an innovative combination of synthetic and theoretical chemistry. Expected outcomes include a markedly increased capacity to access pure samples of L-sugar-based biomolecules, as needed for studying their biological functions. Significant benefits in the development of vaccines, diagnostics and biomaterials are anticipated.Read moreRead less
Radical redox indicators. 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 t ....Radical redox indicators. 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

Deconstructing molecular self-assembly by advanced mass spectrometry. This project aims to develop ion-mobility mass spectrometry methods to observe the molecular evolution of model self-assembly reactions with high temporal and structural resolution, and interrogate the intrinsic gas phase functionality of the assemblies themselves, including aggregation, inclusion and disassembly behaviours. Lack of knowledge of reaction intermediates, mechanisms and kinetics hampers the industrial potential o ....Deconstructing molecular self-assembly by advanced mass spectrometry. This project aims to develop ion-mobility mass spectrometry methods to observe the molecular evolution of model self-assembly reactions with high temporal and structural resolution, and interrogate the intrinsic gas phase functionality of the assemblies themselves, including aggregation, inclusion and disassembly behaviours. Lack of knowledge of reaction intermediates, mechanisms and kinetics hampers the industrial potential of self-assembly to fabricate highly functional materials. This project expects to determine the critical link between the assemblies’ structure and function, and provide the rational framework to optimise and direct synthetic outcomes. This could enable Australian manufacturers to create low-energy production processes of high value commodities.Read moreRead less
