Funding Amount
$731,557.00
Summary
This proposal will develop scientific instrumentation to enable next generation interfacing with the heart and brain using light instead of electricity. Multichannel optical arrays will be fabricated using advanced materials and a control system developed and tested experimentally. The cost-effective technology will enable researchers to enhance our knowledge of the heart and brain with evolving optical approaches and offers future clinical applications for heart rhythm disorders and epilepsy.
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. Ultimately ....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. 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
Methods To Improve Detail Reproduction Of Elastic Impression Materials
Funder

Funding Amount
$96,656.00
Summary
If a dental prosthesis is to fit precisely in the mouth, an accurate impression must be taken of the teeth and surrounding tissues. This research aims to evaluate variable surface conditions which may be taken into consideration to achieve an accurate impression, such as moisture, temperature, and the presence of contaminants. Although any distortions as a result of material interactions would be limited to the surface interface, inaccuracies here may ultimately compromise treatment success.
Next-generation Smart Wound Dressings For Real-time, Non-invasive Monitoring Of Infection And Neovascularisation In Burns
Funder
National Health and Medical Research Council
Funding Amount
$899,877.00
Summary
Real-time assessment of infection and wound progression in burns is critical to reduce complications and improve long-term recovery. We propose a smart dressing that can assess a wound without needing to remove the dressing. It consists of a biocompatible silk membrane enriched with nanodiamonds and pH-sensitive fluorophores to detect infection, and allow optical assessment of blood vessel regrowth. This project will prototype and validate the smart dressing in preparation for human trials.
Improving The Delivery Efficiency Of Nanomedicines To Tumour Tissue
Funder
National Health and Medical Research Council
Funding Amount
$645,205.00
Summary
This research program seeks to develop improved nanomedicines for treating cancer. This will be achieved by targeting the poor delivery efficiency that currently hinders the translation of existing nanomedicines from laboratory to clinic. Successful completion will result in new nanomedicines that effectively target the tumour tissue and display superior therapeutic efficacy, and that will ultimately be developed into new treatments that improve patient outcomes.
Soft carbon nanotube materials. There is no doubt that the realisation of new bionic materials will dramatically improve quality of life for many individuals. The new soft conducting materials proposed will impact on several areas of bionics, including the development of the next generation Bionic Ear, conduits for spinal cord regeneration as well as muscle regeneration and other applications.

Regulating Astrocytosis For Appropriate Defence And Repair Of The Brain After Injury
Funder
National Health and Medical Research Council
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.
Improving Therapeutic Delivery By Understanding Nanoparticle Interactions With Cells

Funding Amount
$553,152.00
Summary
Nanotechnology has the potential to transform the way we treat many diseases. This project will investigate how nanoengineered particles can be used to improve the effectiveness of vaccines. Nanoparticles can protect the delicate vaccine cargo from degradation, and will be targeted specifically to the cells in the body that most effectively induce the maximum theraputic response. This study will improve our understanding of how nanovaccines work and develop new ways of delivering vaccines.
