Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales. These insights and data will be critically important in designing low-friction surfaces that save energy and wear, in developing nanoscopic probes for the mechanical and structural properties of soft polymeric and bio-materials, and in making high performance coatings that control adhesion and particle aggregation in technologically advanced applications.Read moreRead less

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.

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

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.
