By performing chemical separations on a microfluidic scale a reduction in both the cost of analysis and impact of solvent waste on the environment will be achieved.Read moreRead less
A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood. There are about 100 miRNA sequences that are involved in most biological processes. Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of ....A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood. There are about 100 miRNA sequences that are involved in most biological processes. Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of interest to capture the miRNA. Application of a magnetic field allows the levels of miRNA to be detected electrochemically. The expected outcome is a commercialisable biosensor for miRNA both as a diagnostic early detection device and a prognostic device for a range of miRNA biomarkers.Read moreRead less

The project will enhance a newly developed technology for measuring aggregate organic pollution in wastewater. The conventional wet chemistry method is disadvantaged by being slow (2 hr) and requiring toxic heavy metal (mercury, chromium) and hazardous reagents. Aqua Diagnostic's method, by contrast, is rapid (5-10 minutes) and uses only safe chemical reagents. It will be further improved to facilitate unprecedented near-real-time (less than 1 minute) online pollution monitoring and greater analytical robustness. The project will directly benefit the wastewater management community, enrich Australian industry's expertise in nanotechnology applications and grow high-tech exports as this innovative technology continues to penetrate international markets.Read moreRead less

The first generation of single entity measurement tools for analysis: This fellowship project aims to develop a new type of diagnostic device that measures single molecules or single cells. Such measurements seek to revolutionise analysis by allowing heterogeneity and rare events in samples to be identified, rather than the average information provided by existing tools. With single molecule devices, the heterogeneity in response enables the development of multiplexed, calibration free sensors. The outcomes of the project are hoped to be completely new thinking on performing measurements, new knowledge regarding heterogeneity in biology and the potential for novel commercialised sensors. It is expected that this will be important not only in biological discovery, but also in providing far more robust sensors for applications such as environmental monitoring, disease prediction, personalised medicine or drug discovery.Read moreRead less
