Microfluidic devices offer substantial advantages over current technology, in terms of speed, cost of analysis, portability, operator simplicity and safety. Integrating multiple analytical processes within a simple and reliable portable device will lead to application in a range of areas, from pharmacology to therapeutic drug monitoring, proteomic and metabolomic screening for disease diagnosis and drug development, and also for performing clinical diagnostics in a rural area. This will significantly impact on the quality of life of the Nation as a whole, not only due to expedient diagnosis and treatment which has obvious health benefits, but also in the considerable financial benefits that result from early and efficient treatment.

Multimodal biomedical imaging probes: development of advanced polymer nanocomposite devices for oncology. Despite significant research being directed toward cancer treatment, 7.6 million people died world wide in 2007. Early detection and treatment is widely recognised as being effective in significantly reducing mortality rates.

Despite significant research being directed toward cancer treatment, 7.6 million people died world wide in 2007. Early detection and treatment is widely recognised as being effective in significantly reducing mortality rates. Biomedical imaging techniques are routinely used for detection and staging of many cancers. However, greater sensitivity is required so that these techniques can be applied to very early detection of tumours. To overcome this short-coming the next generation of imaging probes will be developed, which will require fundamental investigations in polymer and nanomaterials science to maximise imaging sensitivity and extend probe functionality. Successful outcomes will lead to significant benefits to healthcare in Australia.Read moreRead less
New Strategies for Modelling Polyoxometalates. Polyoxometalates are a versatile class of genuine nanomaterials with remarkable chemical and physical properties and dimensions ranging from tens to tens of thousands of atoms. Designing functional materials which exploit their enormous potential is limited by practical difficulties in their structural characterization and restrictions on our ability to model their behaviour. In this project, we will develop a new strategy for computer modelling of ....New Strategies for Modelling Polyoxometalates. Polyoxometalates are a versatile class of genuine nanomaterials with remarkable chemical and physical properties and dimensions ranging from tens to tens of thousands of atoms. Designing functional materials which exploit their enormous potential is limited by practical difficulties in their structural characterization and restrictions on our ability to model their behaviour. In this project, we will develop a new strategy for computer modelling of polyoxometalates based on the classical molecular mechanics approach and high-level techniques. This novel line of attack will be exploited in the characterization of large and highly substituted derivatives which are key to developing functional materials.Read moreRead less
Enhancing Selectivity and Detection in Miniaturised Analytical Separation Systems. Miniaturisation-compatible stationary phases and detection techniques will be developed for microseparation techniques of capillary electrochromatography and chip-based separation systems, and their analytical applications will be investigated. Replaceable stationary phases (RSP) of chromatographic particles suspended in reversible gels will be created by delivering a liquid RSP to the column followed by in situ ....Enhancing Selectivity and Detection in Miniaturised Analytical Separation Systems. Miniaturisation-compatible stationary phases and detection techniques will be developed for microseparation techniques of capillary electrochromatography and chip-based separation systems, and their analytical applications will be investigated. Replaceable stationary phases (RSP) of chromatographic particles suspended in reversible gels will be created by delivering a liquid RSP to the column followed by in situ immobilisation. This approach offers flexibility in optimising a number of parameters of the column and of its use for sample pre-treatment and preconcentration. Pulsed potentiometric detection will be developed for the abovementioned microseparation techniques, combining the advantages of pulsed amperometric techniques with the more universally responding potentiometric detection.Read moreRead less

Australia is strongly investing in nanotechnology and through the governments priority goals 'Frontier Technologies for Building and Transforming Australian Industries' it has been recognised as an important area for investment. This proposal will help develop an internationally recognised nano-industry. It is envisaged that the particles made during this work will have direct implications for the public - creating a new class of medical diagnostic particles with better resolution and specificity. These particles have the potential to diagnose patients more precisely and at an earlier stage than is currently available. Additionally, these particles could be designed to load drugs and hence could be used to treat diseases such as cancer.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.

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 vaccines. In the future we hope that our technology will be simple enough for routine diagnosis, even in the Outback where doctors are hundreds of kilometres awayRead moreRead less

The influenza virus continues to pose a serious health risk to Australians and remains a leading cause of death. The molecular characterisation of emerging strains of the virus lies at the heart of current surveillance procedures vital to vaccine preparation and the development of new anti-viral drugs. This research will advance a world-first proteomics surveillance of the virus developed in this laboratory that will enable it to be characterised in-field at the site(s) of infection outbreaks. This rapid response is vital, particularly in the event of a pandemic or a deliberate release of the virus in a bioterrorist attack.Read moreRead less
