Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded ....Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded nano-Radiators (SUPER) Dots), based on purpose-engineered up-conversion nanocrystals that are ultra-bright and have low background interference, high specificity, speed, and large-scale multiplexing capacity. These probes will allow microscopy and flow cytometry to measure hitherto undetectable rare-event molecules and cells, opening new frontiers for the discovery of new biomarkers.Read moreRead less
Lipidomics of vision. Presbyopia and cataract are the major causes of visual impairment worldwide. Nevertheless, our understanding of lens ageing at both a cellular and molecular level is limited. This project will gain new insight into the effect of age on lens membrane lipids and their role in the development of presbyopia and cataract.
Harnessing the bioactivity of proteins and polypeptides: understanding and controlling adsorption processes to optimise linker free immobilisation. This project will use physical techniques and simulations to understand the interactions of biomolecules and plasma activated surfaces, allowing control of the biomolecule layer composition, orientation and conformation. This control, together with the ability of these surfaces to "lock-in" the optimised layer, will create a new generation of biodevi ....Harnessing the bioactivity of proteins and polypeptides: understanding and controlling adsorption processes to optimise linker free immobilisation.

Soft carbon nanotube materials. There is no doubt that the realisation of new bionic materials will dramatically improve quality of life for many individuals. The new soft conducting materials proposed will impact on several areas of bionics, including the development of the next generation Bionic Ear, conduits for spinal cord regeneration as well as muscle regeneration and other applications. This project will further enhance the international profile of the ARC Centre of Excellence for Electro ....Soft carbon nanotube materials.

The new soft conducting materials proposed will impact on several areas of bionics, including the development of the next generation Bionic Ear, conduits for spinal cord regeneration as well as muscle regeneration and other applications. This project will further enhance the international profile of the ARC Centre of Excellence for Electromaterials Science in the field of Bionics. The end-user network already in place will ensure all opportunities are fully exploited.Read moreRead less
Molecular and immunological approaches to managing Australia's seafood allergy epidemic. Seafood is an increasingly important cause of food allergy. Novel insight into the functions of why and how proteins from seafood develop to potent allergens will lead to the development of better diagnostics and therapeutics. This will assist patients to better manage their serious food allergy.
The Protein Corona: Imaging the nanoparticle biological identity card. The project will determine how the intrinsic physico-chemical properties of nanoparticles translate into extrinsic biological properties through their interaction with physiological proteins in the body. This process is complex and poorly understood due to our inability to visualise it through standard imaging techniques. The project aims to develop a new tool to visualise, study, quantify and design the protein ‘corona’. The ....The Protein Corona: Imaging the nanoparticle biological identity card. The project will determine how the intrinsic physico-chemical properties of nanoparticles translate into extrinsic biological properties through their interaction with physiological proteins in the body. This process is complex and poorly understood due to our inability to visualise it through standard imaging techniques. The project aims to develop a new tool to visualise, study, quantify and design the protein ‘corona’. These are the adsorbed protein layers that are rapidly formed in contact with biological liquids which allow cells to recognise and process nanoparticles. The proteins are dependent on factors such as size, shape, surface chemistry and biological history of the particles. Being able to ‘read’ and ‘write’ the protein corona would enable efficient cellular targeting of pharmaceutical drugs.Read moreRead less
Roles of the kynurenine pathway in physiological and pathological brain function. This project will aim to study the metabolism of the essential amino acid tryptophan in the brain and its involvement in diseases including multiple sclerosis and brain tumours.
Defining disease: Addressing the problem of overdiagnosis. This project will investigate and define the limits of physical disease, to answer questions about when a presentation is a disease, and when it is simply a risk factor or mild condition. The ensuing account of disease will make a practical contribution to growing international concern about asymptomatic people being diagnosed and treated for conditions that will not cause any health problems ("overdiagnosis"). The research will provide ....Defining disease: Addressing the problem of overdiagnosis. This project will investigate and define the limits of physical disease, to answer questions about when a presentation is a disease, and when it is simply a risk factor or mild condition. The ensuing account of disease will make a practical contribution to growing international concern about asymptomatic people being diagnosed and treated for conditions that will not cause any health problems ("overdiagnosis"). The research will provide normative grounds for evaluating disease claims. Results will reduce the harm caused by people receiving treatment that they do not require, make a practical contribution to debates about the scope of health care, and yield findings that can help to reduce the cost-burdens associated with overdiagnosis.Read moreRead less
Small heat shock proteins: front-line defenders and therapeutic targets. Small heat-shock chaperone proteins play a key role as front line defenders against protein aggregation, a process linked to ageing and disease. This project spans fields from protein chemistry to cell biology to generate an unprecedented insight into the links between the structure, function and therapeutic potential of these chaperone proteins.
Mapping dynamic lipid biochemistry with high spatial and molecular detail. Lipids are a complex and underappreciated family of molecules playing important roles in all of our tissues and cells. Yet, our fundamental knowledge of lipids is limited by current technology. This project aims to develop an innovative mass spectrometry imaging platform allowing lipid biochemistry to be visualised at a level of detail not before possible. This will push boundaries in molecular imaging technology and is e ....Mapping dynamic lipid biochemistry with high spatial and molecular detail. Lipids are a complex and underappreciated family of molecules playing important roles in all of our tissues and cells. Yet, our fundamental knowledge of lipids is limited by current technology. This project aims to develop an innovative mass spectrometry imaging platform allowing lipid biochemistry to be visualised at a level of detail not before possible. This will push boundaries in molecular imaging technology and is expected to provide new fundamental knowledge about the structure, function and distributions of lipids in tissues and cells. Significant benefits should include providing new tools to unravel the functions and modifications of lipids in biology, that can be extended to many other research and industrial applications.
