Tuneable “Nano-Shearing”: An Innovative Mechanism for the Accurate and Specific Capture of Cells and Molecules. Recent investigations have discovered a tuneable electro-hydrodynamic force which drives lateral fluid motion within a few nanometers of an electrode surface. Because the magnitude of this fluid shear force can be tuned externally (for example, via the application of an AC electric field), it provides a new capability to physically displace weakly (non-specifically) bound cellular and ....Tuneable “Nano-Shearing”: An Innovative Mechanism for the Accurate and Specific Capture of Cells and Molecules. Recent investigations have discovered a tuneable electro-hydrodynamic force which drives lateral fluid motion within a few nanometers of an electrode surface. Because the magnitude of this fluid shear force can be tuned externally (for example, via the application of an AC electric field), it provides a new capability to physically displace weakly (non-specifically) bound cellular and molecular analytes. By performing research to further understand and develop this tuneable effect, this project aims to build and test a new platform technology to enable highly efficient capture and specific detection of low concentration pathogenic molecules and circulating tumour cells (CTCs).Read moreRead less

This project aims to develop a novel device, comprising advanced single molecule imaging, microfluidics and immunoassay technologies, for quantification of milk protein variants. Milk quality is central to dairying and variants of proteins in milk affect its market value. No current milk protein detection technologies are readily applied in milk production quality control. This project aims to produce a device that can be used by milk producers and farms to profile protein variants with high sensitivity in a single test in an hour and screen unwanted protein contamination. The platform also has great potential for detecting other complex and low content analytes. It builds on innovations in nanoparticles and recent industry collaboration.Read moreRead less

Solid-state light sources for bio-imaging and microfluidics. Solid state light sources are the light sources of the 21st century. This project will allow us to find new ways of bioimaging in living organisms applicable to diagnosing disease, and for microfluidic chip based portable instruments for on-site and point-of-care analysis in medical diagnostics, environmental monitoring, and manufacturing processes.
Strategies for the detection of designer steroids in racehorses. The Australian racing industry drives economic activity and contributes $1 billion to GDP, $151 million Government revenue and 50,000 jobs in NSW. Racing depends on maintaining the highest standards of integrity. This project will make Australia a world leader by developing robust methods to detect designer steroids in thoroughbred racing.
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.

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

Photodissociation mass spectrometry for lipidome analysis. This project aims to develop and apply novel bioanalytical mass spectrometry-based methods and workflows to illuminate the otherwise hidden structural diversity and molecular complexity of the lipidome.

This project aims to develop and apply novel bioanalytical mass spectrometry-based methods and workflows to illuminate the otherwise hidden structural diversity and molecular complexity of the lipidome. The structure of individual lipids define their specific biological functions. A major requirement of analytical methods employed for lipid analysis on a lipidome-wide scale, therefore, is to enable the detailed structural characterisation of the, potentially, tens of thousands of individual molecular lipid species that may be present within a sample of interest. This project will develop and optimise novel, ultraviolet photodissociation-tandem mass spectrometry methods which will be integrated within an automated lipidome analysis workflow, to enable comprehensive global lipidome profiling and to reveal the structural diversity of lipids involved in fundamental cellular signalling processes.Read moreRead less
