Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites.

Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately microelectronic engineering methods will be used. This will give control over the attachment process with potential benefits of orienting attaching molecules, minimising non-specific attachment and enriching diagnostics by enabling interrogation of the force of attachment.Read moreRead less
Engineering quantum-size bioceramics: Photocatalytic / sonocatalytic ceria. This project aims to design and engineer photocatalytic ceria of systematically controlled grain sizes and morphologies, using doping methods to achieve pure and mixed quantum confinement (which enhances performance). The intended outcomes of the computation, fabrication, and validation approach are a fundamental knowledge of the processing-performance matrix and reproducible photocatalysts of optimised performance.

This project aims to design and engineer photocatalytic ceria of systematically controlled grain sizes and morphologies, using doping methods to achieve pure and mixed quantum confinement (which enhances performance). The intended outcomes of the computation, fabrication, and validation approach are a fundamental knowledge of the processing-performance matrix and reproducible photocatalysts of optimised performance. While these ceramics will be applied as bioceramics, which can be activated by ultraviolet light, X-rays and ultrasound, the benefits will be applicable in energy (solar cells, photoelectrodes) and the environment (air and water purification).Read moreRead less

Regulating Astrocytosis For Appropriate Defence And Repair Of The Brain After Injury

Funding Amount
$562,742.00
Summary
An inflammatory process, designed to clean up cell debris and maintain tissue integrity following brain insult, also results in an astrocytic scar that biochemically impedes nerve repair. After 8 weeks astrocytes switch to become supportive, however once a scar is formed repair is permanently inhibited. Here, we will test the ability of biomaterials to optimise the timing of the necessary inflammatory phase, to encourage repair by converting astrocytes to their tropic phase more rapidly.

Summary
Bone injury is a common and profoundly debilitating issue, and is responsible for extended partial or complete loss of mobility and associated economic impact during slow healing. There is strong demand for technology that reduces the time taken for bone repair. There is still a paucity of clinically effective biocompatible materials for treatment. We have developed a novel approach for a thermoresponsive hydrogel with unique properties suitable for rapid bone filling and regeneration.
Designing functional biomaterials with superior cellular interactions. This proposal aims to make a new class of biomaterials that direct important cellular functions such as adhesion, proliferation, and differentiation. This will be achieved by developing materials that leverage a previously unexplored mechanism that was recently identified in my lab: the co-engagement of integrin and syndecan-4 cell receptors.

Summary
Osteoporosis affects 1.2 million Australians and will cost $33.6 billion by 2022. This study aims to develop a novel nano-cement platform for custom-designed bone repair in osteoporosis, by using purpose-designed nanomaterials and advanced 3D printing technique. The research findings will lead to the development of a new bone repair strategy, expand knowledge on both biomaterials engineering and osteoporosis treatment, and improve the quality of life of Australians.
