SILICON BASED PHOTONIC CRYSTALS FOR MONITORING BIOMOLECULAR INTERACTIONS. Two great goals of biomolecular science are to monitor biomolecular interactions in real time and with sufficient sensitivity to allow small amounts of biological material to be investigated. The achievement of these goals is limited by the methods of transducing these reactions.

Two great goals of biomolecular science are to monitor biomolecular interactions in real time and with sufficient sensitivity to allow small amounts of biological material to be investigated. The achievement of these goals is limited by the methods of transducing these reactions. The aim of this multidisciplinary proposal is to overcome this limitation by developing photonic devices that exploit the unique properties of nanoporous silicon. The hybridisation of DNA will be used as a model biorecognition reaction. Potential applications of these photonic devices are as highly sensitive affinity sensors and as tools for investigating the kinetics of biomolecular interactions.Read moreRead less
The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, t ....The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, this project aims to uncover the link between the unique geometry of HIV capsids and their ability to subvert the nucleus’ defenses. The expected outcome is a step-change in the understanding of nuclear access control, with downstream benefits to virology, bio-engineering and bio-technology.Read moreRead less
Biophysics of the brain’s waste disposal system: Understanding why we sleep. This project aims to develop a new biophysical model of the brain, founded on the recently discovered glymphatic system responsible for waste disposal during sleep. It sets out to formulate, analyse, and validate rigorous new multiscale quantitative modelling – to advance the study of sleep and brain clearance dynamics, at timescales from hours to decades.

This project aims to develop a new biophysical model of the brain, founded on the recently discovered glymphatic system responsible for waste disposal during sleep. It sets out to formulate, analyse, and validate rigorous new multiscale quantitative modelling – to advance the study of sleep and brain clearance dynamics, at timescales from hours to decades. Among expected outcomes are powerful models ready for application at both population and individual level, and testable predictions concerning the sleep patterns that lead to aggregation of waste in the brain and eventual cognitive decline. Project outcomes should also benefit society and the economy though translation into interventions for sleep disturbance – in future applied research.Read moreRead less

We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.Read moreRead less

Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods. This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data.

Cardiac diseases kill more Australians than any other disease group. According to the National Heart Foundation the prevalence to heart conditions increased by 18% over the last decade.
Medical practitioners are in need of reliable diagnostic tools to decide whether a person in front of them is at high risk from developing sudden cardiac death, and whether they should be fitted with an implant that could save their life.Read moreRead less
