Sport is a critical area for social and economic investments. Novel medical monitoring systems using implantable biosensors will ensure optimal training programs for Australian athletes and maintain international competitiveness. Here we are developing a biosensor for real-time monitoring of lactate levels in athletes using frontier porous semiconductor technology and smart telemetry protocols to transfer the readings to a remote base unit. These highly innovative devices and the materials that they are made from have enormous commercial potential in biomedical engineering. There is a strong potential for Australia to have an important stake in this area by combining expertise in engineering, chemistry and nanostructured materials.Read moreRead less
New uses for milk-derived products for eradication of Helicobacter pylori infection and gastro-intestinal site-specific delivery of active agents. Helicobacter pylori is the most significant bacterial pathogen in the world, infecting 50% globally. Current treatments are inducing rapid antibiotic resistance and are thus becoming increasingly less effective. The infection is acquired in childhood and new methods to prevent and/or treat the infection, minimising acquisition of antibiotic resistance ....New uses for milk-derived products for eradication of Helicobacter pylori infection and gastro-intestinal site-specific delivery of active agents. Helicobacter pylori is the most significant bacterial pathogen in the world, infecting 50% globally. Current treatments are inducing rapid antibiotic resistance and are thus becoming increasingly less effective. The infection is acquired in childhood and new methods to prevent and/or treat the infection, minimising acquisition of antibiotic resistance are urgently required. This project seeks to develop new ways of doing this that combine novel antibacterials with techniques to deliver them (and monitor this delivery) as well as modify the complex protective habitat in the stomach.Read moreRead less
Investigation of three dimensional terahertz computed tomography for biomedical applications. Terahertz (T-ray) imaging is an exciting newly emerging technology that can perform safe, non-invasive, imaging and chemical sensing at the same time. This research aims to achieve an advance in terahertz imaging by using advanced methods that will enhance our ability to achieve accurate detection of diseased tissue in vivo. Socio-economic benefits to Australia include: (i) contributions to terahertz sy ....Investigation of three dimensional terahertz computed tomography for biomedical applications.

Porous silicon biosensor for rapid detection of water-borne contaminants. We have recently demonstrated the rapid degradation of porous silicon by certain transition metal complexes known as biomimetic catalysts. The catalysed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. Using this mechanism, we will develop a biosensor for the rapid detection of contaminants (toxins etc.) in water resources. Reservoir w ....Porous silicon biosensor for rapid detection of water-borne contaminants. We have recently demonstrated the rapid degradation of porous silicon by certain transition metal complexes known as biomimetic catalysts. The catalysed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. Using this mechanism, we will develop a biosensor for the rapid detection of contaminants (toxins etc.) in water resources. Reservoir water treatment today is reactive rather than preventive because current analysis is slow. Our biosensor can be turned into a field kit to improve water quality management and prevent acts of deliberate sabotage to the water supply.Read moreRead less

The catalyzed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. This project uses porous silicon degradation to develop a biosensor platform capable of detecting a range of analytes with high sensitivity. The project includes detection of an water-borne toxin, a plant virus and a cancer antigen as demonstrators of its wide applicability. Multiplexing of the biosensor to demonstrate its potential as high-throughput chip sensors is also included.Read moreRead less
