Summary
Scanning Probe Microscopy for Bioelectrochemistry. New methods to study the fundamental properties of biological samples, in particular proteins, are continuing to advance and impact on society. We will establish a leading edge facility for high-resolution imaging of biomolecules with redox functions. This will enable the continued development of new enzyme based diagnostic tests by understanding the dynamic nature of coupled electron and molecular interactions with redox enzymes in solution.

The bioelectrochemical imaging facility will be unique in Australia and establish an important cross-disciplinary approach within the international community.Read moreRead less
Biomedical imaging with spins in nanoparticles: from single cell to whole-body scanning. The engineering of new biomedical technology is critical in underpinning our understanding of physiology and in the early detection of disease. This project will construct novel instrumentation for investigating normal and diseased physiology using bioagents based on diamond and ruby nanoparticles. The imaging and tracking techniques proposed are non-invasive, nontoxic, and provide high-resolution access to ....Biomedical imaging with spins in nanoparticles: from single cell to whole-body scanning. The engineering of new biomedical technology is critical in underpinning our understanding of physiology and in the early detection of disease. This project will construct novel instrumentation for investigating normal and diseased physiology using bioagents based on diamond and ruby nanoparticles. The imaging and tracking techniques proposed are non-invasive, nontoxic, and provide high-resolution access to specific physiological interactions of paramount importance in, for instance, understanding cancer pathways and developing strategies for targeted drug delivery.Read moreRead less
Solving the problem of detecting small molecules in complex samples: A Label-Free Electrochemical Immuno-biosensor for drugs and pesticides. Biosensors are portable analytical devices which can be used by the general public without specialist training. The proposed research will develop a biosensor for the detection of small molecules such as pesticides, poisons and drugs; a class of analytes where there is currently no viable biosensor technology. The simple to use device will benefit the Aus ....Solving the problem of detecting small molecules in complex samples: A Label-Free Electrochemical Immuno-biosensor for drugs and pesticides. Biosensors are portable analytical devices which can be used by the general public without specialist training. The proposed research will develop a biosensor for the detection of small molecules such as pesticides, poisons and drugs; a class of analytes where there is currently no viable biosensor technology. The simple to use device will benefit the Australian community by providing technology which will allow rapid and inexpensive monitoring of water as well as biomedical diagnosis. The research will also benefit Australia via providing the training of scientists to establish the new generation of Australia's bionanotechnology industry. Read moreRead less
Liquid light: aqueous bio-sensing in microstructured polymer optical fibres. This project builds on Australia's world-leading position in the development of microstructured polymer optical fibres, and applies the unique benefits they provide to for ultra- sensitive bio-sensing. By using the microstructure to simultaneously confine light and liquid, microstructured optical fibres provide a unique platform for ultra-sensitive spectroscopy and structural studies of biomolecules in solution.

A Three-Dimensional Ultra-Wideband Microwave Method Based On Multiple Antennas For Early Detection Of Breast Cancer. Breast cancer is the most common cause of cancer-related death among women in Australia. In 2003, it killed 2,713 women in Australia and approximately 400,000 worldwide. Despite significant advances, current breast screening methods still suffer from several limitations. They may miss as many as 15% of cancers. Inconclusive results are common, leading to invasive, expensive and pa ....A Three-Dimensional Ultra-Wideband Microwave Method Based On Multiple Antennas For Early Detection Of Breast Cancer. Breast cancer is the most common cause of cancer-related death among women in Australia. In 2003, it killed 2,713 women in Australia and approximately 400,000 worldwide. Despite significant advances, current breast screening methods still suffer from several limitations. They may miss as many as 15% of cancers. Inconclusive results are common, leading to invasive, expensive and painful follow-up tests such as biopsies. About 75% of such biopsies are found to be negative, and this is a major deterrent for women in undertaking breast screening. The proposed project contributes to the cause of finding a more reliable breast cancer detection method, and hence, saving thousands of lives each year.Read moreRead less
The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form ....The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form the double helix. The occurrence of hybridization is determined by differences in surface force measurements compared with when only the single strand of DNA is present. In this way DNA samples can be analyzed without amplification; a major advance for DNA diagnostics.Read moreRead less
Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,00 ....Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,000 Australians who wear contact lenses. This collaborative research directly supports the mission of a respected non-profit organisation (Institute for Eye Research) and will train scientists in world-leading analytical technologies that are essential to Australia's emerging biotechnology industries.Read moreRead less
