Nutritional ecology of predatory arthropods: molecular analysis of gut contents to elucidate prey choice and diet breadth. The evolution of genetic resistance in insect pest populations against synthetic and biological pesticides requires new integrated pest management strategies with increasingly large biological control components.

The evolution of genetic resistance in insect pest populations against synthetic and biological pesticides requires new integrated pest management strategies with increasingly large biological control components. This is the only sustainable approach to pest management in agricultural production and natural ecosystems. Biological control of insect pests can potentially be achieved with indigenous generalist predators, thereby reducing the risks associated with importing exotic natural enemies. This project provides new opportunities for enhancing biological control by examining the diets of generalist predators using new diagnostic technologies. This is crucial for the effective and reliable use of predators in biological control.Read moreRead less

Detection and Quantification of General Fetal Movements from Accelerometer Measurements using Nonstationary Signal Processing Techniques. There are approximately 1,750 fetal deaths per year in Australian with about one-third occurring late in gestation and without an apparent cause. The development of an automated system capable of long-term monitoring of fetal health will result in accurate diagnoses and prediction of future outcome.

There are approximately 1,750 fetal deaths per year in Australian with about one-third occurring late in gestation and without an apparent cause. The development of an automated system capable of long-term monitoring of fetal health will result in accurate diagnoses and prediction of future outcome. This will, in turn, allow early intervention by the clinician to reduce fetal deaths and enhance the chances of good outcomes with resultant savings in social and financial costs to the community. The development of such equipment would spawn future research into intervention treatments and contribute to Australia's position as a world leader in computerised health monitoring systems.Read moreRead less

Non-invasive diagnosis using micropatches that sample biomarkers from skin. We are developing a technology called the micropatch that is laid onto the surface of the skin. When the patch is pulled away, it retains proteins found in the subsurface skin layers. We believe that by analysing these proteins we will be able to diagnose diseases like cancer earlier and therefore have a better chance of treating them successfully. The process is painless, and doctors already use it to give drugs and vac ....Non-invasive diagnosis using micropatches that sample biomarkers from skin.

A new approach is proposed for the development of novel micro- and nano-scale solid-phase adsorbent materials. These materials are based on porous polymer monoliths formed in situ within a capillary acting as a mould. The allows the material to be readily placed in a defined position, in a process similar to photo-patterning, and alleviates many of the problems usually associated with fabrication and miniaturisation. A simple photo-grafting process, initiated by UV light can be used for the selective chemical modification of these materials. These tailored monoliths can then be used for the in-line coupling of biological sample handling and capillary electrophoresis (CE) for the determination of drugs and related metabolites in biological fluids, thus avoiding time-consuming and costly off-line sample pre-treatment. This will lead to the development of new methods for the rapid determination of drugs, metabolites and other small molecules in clinical samples.Read moreRead less

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.

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
