Summary
Integrated Nanoscale Biosystems Network (INBN). The INBN will integrate high-priority research, already identified by the ARC, in materials nanoscience and engineering with nanoscale biology. The INBN will provide the means to consolidate world-class multidisciplinary Australian research groups in existing Centres of Excellence, including several Federation Fellows, into a nanobiotechnology focus.

The INBN will provide the means to consolidate world-class multidisciplinary Australian research groups in existing Centres of Excellence, including several Federation Fellows, into a nanobiotechnology focus. The significant outcomes of INBN are the critical mass of outstanding researchers in the nanobiosciences, facilitation of innovative research to produce novel intellectual property and provision of pathways into collaborative research with international scientists and industry, and the training and development of the next generation scientists for this emerging discipline.

Broad spectrum nanomedicine for Meningitis treatment. Brain inflammatory diseases are among the top ten infectious causes of death. The project aims to provide Australian doctors with a superior alternative of treating infections that do not respond to conventional antibiotics. The nanomedicine developed will reduce the burden of hospital and boost Australia economy in the biomedical sector.

Dual column focused ion beam/scanning electron microscope facility: This facility will precisely cut specimens and surfaces that can be imaged in a variety of ways, including crystallographic and elemental space, of particular use for physical scientists, as well as biological specimens. This instrument will provide information at resolutions between optical and transmission electron microscopy, images that will effectively provide the biologist with the ability to develop the complete correlative picture of organelles and cells. The instrument will also provide a much needed resource for researchers across disciplines such as physics, chemistry, biology, geology and engineering.Read moreRead less
Failure of Complex Biomechanical Structures. Layer structures are replete in biological systems, both natural and artificial. Issues concerning the lifetime of such systems are paramount to the quality of life and economic well being of our aging society. Our project will analyse damage in brittle layer systems that simulate dental crown structures.

Layer structures are replete in biological systems, both natural and artificial. Issues concerning the lifetime of such systems are paramount to the quality of life and economic well being of our aging society. Our project will analyse damage in brittle layer systems that simulate dental crown structures. We are now at a critical point in the understanding of how these structures fail, and are beginning to make substantive predictions to improve designs for prolonged life. The project is connected to the dental community and international crown material manufacturers through a broader NIH project in the USA. The improved materials and crown designs resulting from this project will have impact worldwide, including Australia.Read moreRead less
Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U ....Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U.S.A. An understanding of the factors that maximise the containment of cracks is essential to the design and development of the next generation of advanced layer composites for many biomechanical and other engineering applications.Read moreRead less
Survival mechanisms of teeth. The patterns of fracture in teeth can be used to infer bite forces and dietary habits in human ancestors and other animals, yet the link between the fracture pattern and forces is not yet well understood. This project will enable new developments in the field of evolutionary biology by providing mathematical models that can predict these forces.

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, whic ....Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less

This project will lead to the development of new biocompatible, biodegradable, porous materials ideally suited to many applications in tissue engineering. These new biomaterials will be relatively inexpensive to manufacture, via simple processes using non-toxic reagents. The key properties of the biomaterials will be controllable by appropriate choice of starting materials. The availability of these new biomaterials will facilitate future developments in tissue engineering, which will ultimately lead to improved medical outcomes in areas as diverse as joint and bone repair and organ regeneration. Local manufacture of these biomaterials would also contribute to the development of the Australian biotechnology industry.Read moreRead less
