Companies in Australia and in the rest of the world are now developing biochips for genome sequencing and point-of-care diagnosis. DNA biochips have the potential to provide simple, fast and accurate clinical analysis, thus enhancing the efficiency of medical treatments and reducing the costs of health care.
The structural properties of the immobilized DNA are critical for determining the DNA chip sensitivity and efficiency. A fundamental understanding of the molecular interactions at the surface of a biochip is therefore not only relevant for the scientific community, but can have direct implications for the design of improved DNA chips.Read moreRead less

A comparative study of the laser-tissue interaction between solid state 213nm vs excimer gas 193nm laser systems. We will carry out a comparative study of the latest technological developments in laser vision correction surgery. We will compare the biological effects of a new solid state laser operating at 213nm and a traditional excimer gas laser operating at 193nm. For each laser type, long-term scarring, cytotoxicity, mutagenicity and free radical production will be studied in relevant in viv ....A comparative study of the laser-tissue interaction between solid state 213nm vs excimer gas 193nm laser systems. We will carry out a comparative study of the latest technological developments in laser vision correction surgery. We will compare the biological effects of a new solid state laser operating at 213nm and a traditional excimer gas laser operating at 193nm. For each laser type, long-term scarring, cytotoxicity, mutagenicity and free radical production will be studied in relevant in vivo and in vitro animal models. Furthermore, optimization of the irradiation protocol for the solid state laser will lead to the development of a wide range of biological applications.Read moreRead less
Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer t ....Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer tissue state and morphology indirectly based on phase delay, speckle, and angle-resolved scattering. We will break new ground in correlating the structure and function of in situ epithelial tissue and cells to light scattering enabling, e.g., the detection of mitosis and apoptosis in cells buried in thick, turbid media, and of cancers and precancers in vivo.Read moreRead less
Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currentl ....Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currently not possible. We also plan to make advances in the key area of scanning delay line technology by employing acousto-optics in OCT for the first time. Acousto-optics conveys advantages in no-moving-parts, scan-speed and accuracy.Read moreRead less

This project brings together an international, multi-disciplinary team to develop innovative, high-resolution techniques to identify diseased tissue. Success will result in a new medical imaging technique allowing clinicians to quantify the mechanical properties of tissue, effectively creating a high-resolution image of what the tissue 'feels' like. This may help them to more accurately identify cancerous tissue during surgery and reduce rates of recurrence. It could aid in tissue engineering and regeneration and will provide a new database of tissue mechanical properties. The project will position Australia as a leader in this newly developing medical imaging technology, with significant potential for commercialisation.Read moreRead less
