Nanotechnology - science at the scale of a billionth of a metre - rests on our ability to manipulate molecules and to build structures that will be part of useful devices. We shall develop new methods to put that chemistry on carbon surfaces - leading to very stable and cheap devices that will have 'real world' applications in environmental monitoring. A 'bottom up' method of fabrication exploits the ability of similar molecules to line up on a suitable surface, so-called 'self Assembly'. The project is based on sound fundamental science for an applied research outcome and therefore will enhance Australian's standing as a strong scientific country that applies its knowledge at the forefront of technological advancement.Read moreRead less
New Strategies for Monitoring DNA-Anticancer Drug Interactions. The highly successful cisplatin works by binding to DNA and partially unwinding or bending the DNA. As a consequence of the success if cisplatin, alternative anticancer drugs are being developed with reduced side effects for patients. One of the bottom necks in the development of alternative drugs is rapid screening of the efficacy on new leads. The proposed research will develop new technologies for monitoring DNA-drug binding, ....New Strategies for Monitoring DNA-Anticancer Drug Interactions. The highly successful cisplatin works by binding to DNA and partially unwinding or bending the DNA. As a consequence of the success if cisplatin, alternative anticancer drugs are being developed with reduced side effects for patients. One of the bottom necks in the development of alternative drugs is rapid screening of the efficacy on new leads. The proposed research will develop new technologies for monitoring DNA-drug binding, DNA damage and DNA repair using novel DNA biosensors. the novelty of the biosensor technology will be to use the modulation of charge transfer through DNA as a method for determining the structural changes that occur in DNA due to these events occurring.Read moreRead less
In-field sensors for the detection of illicit drugs. Presumptive field test kits for illicit drugs analysis are typically based on chemical spot tests that produce a coloured product. While relatively easy to apply, such test kits (containing wet chemicals) produce inconclusive colour changes lacking sensitivity, and selectivity requiring a subjective assessment by the examiner. Despite these limitations, these test kits are in widespread use and are routinely used. This study aims to develop s ....In-field sensors for the detection of illicit drugs. Presumptive field test kits for illicit drugs analysis are typically based on chemical spot tests that produce a coloured product. While relatively easy to apply, such test kits (containing wet chemicals) produce inconclusive colour changes lacking sensitivity, and selectivity requiring a subjective assessment by the examiner. Despite these limitations, these test kits are in widespread use and are routinely used. This study aims to develop specific in-field sensors for the detection and identification of illicit drugs. This would significantly enhance the ability of Forensic Services staff to confirm the identity of seized material. Increased specificity would provide valuable early advice to investigators regarding the nature of a seizure and would reduce the likelihood of false positive results. Increased sensitivity would permit the analysis of trace amounts of material from individuals or locations related to an illicit drug consignment.Read moreRead less

We will develop a number of techniques for the controlled growth of nanowires and making functional nanoscale systems such as nanosensors. The nanosensors will have important applications in chemistry and biology. Some chemical species can be detected by nanosensors on molecular scale. The nanosensors could be used for early diagnostics of cancer disease, detection of viruses, and genomic DNA screening. The nanosensors could also provide a molecular tool for probing living cells without destroying them, through which we can track life within cells in real time.Read moreRead less

Cancer and diseases of the central nervous system (CNS) represent two of the major health challenges facing Australia because of the aging population. In order to address these challenges we need to develop methods for identifying tumours and CNS diseases using non-invasive technologies and at an early stage so that treatments can be applied when they are most likely to work. In this project, we are developing new radiolabelled compounds that will enable the imaging of tumours, tumour metastases and CNS diseases states.Read moreRead less

This project aims to prepare alpha-hydroxyketones and gingerol derivatives acting at vanilloid (VR1) receptor with potential analgesic activity. These compounds will be tested for their ability to activate the VR1 receptor, desensitize the receptor and release neuropeptides associated with pain pathways. The development of these novel compounds will contribute towards understanding the mechanisms of VR1 receptor activation and provide information on how the VR1 receptor is regulated. We will determine and compare neurotoxicity of these compounds to capsaicin which is known to possess neurotoxic activity. The outcome of this project may result in effective agents for better pain management.

Many cells are damaged when they are chilled below body temperatures thus limiting shelf-life for applications. For example, storage of human blood platelets is limited to 5 days at 22 degrees. This research will produce molecules that can be used in the fields of agriculture (in vitro fertilization techniques, development of improved blood lines), aquaculture and human reproductive technologies, where ice crystal growth and freezing are damaging. This outcome will be achieved by the synthesis of molecules that mimic natural products that allow fish to survive in the icy Arctic and Arctic Oceans and study how they are able to protect cells and tissues from damage in these extreme environments.Read moreRead less

Water at Hydrophobic Surfaces. The properties of water define the nature of life on this planet. When water encounters a hydrophobic surface - at the air/water interface, in contact with unreactive solids such as Teflon, or at an oil drop, our recent experiments indicate that the water dissociates more readily into protons and hydroxide ions - undergoes autolysis - than in bulk water. Furthermore, the hydroxide ions are preferentially adsorbed at the surface, giving it a negative charge. This pr ....Water at Hydrophobic Surfaces. The properties of water define the nature of life on this planet. When water encounters a hydrophobic surface - at the air/water interface, in contact with unreactive solids such as Teflon, or at an oil drop, our recent experiments indicate that the water dissociates more readily into protons and hydroxide ions - undergoes autolysis - than in bulk water. Furthermore, the hydroxide ions are preferentially adsorbed at the surface, giving it a negative charge. This project will test the generality and implications of this novel concept. The results will range across physics, chemistry, biology and their associated technologies, a consequence of the ubiquitous importance of water. Read moreRead less
