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

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
Development of an ultrasensitive assay for human prion proteins. The aim of this work is to enable the detection of prion proteins in human blood and other tissues. The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and bl ....Development of an ultrasensitive assay for human prion proteins.

The outcome of the work is expected to facilitate the production and certification of prion-free blood and blood products. Prions cause Bovine Spongiform Encaphalopathy and Creutzfeld Jacob Disease and attempts to control of these diseases would be greatly abetted by an optimal test for the disease-causing agent.Read moreRead less

An 800 MHz high-resolution nuclear magnetic resonance (NMR) spectrometer equipped with a triple-resonance cryoprobe is required to support the research of 5 universities in the NSW/ACT area. The high magnetic field of the spectrometer is necessary for the study of proteins, protein-ligand complexes and other biomolecular systems of molecular weight >30,000. Projects previously inaccessible due to sensitivity, solubility or resolution problems will become tractable. The increased turn-around times afforded by the high sensitivity of the cryo-enabled spectrometer make it possible to provide access for Australian institutions that would not otherwise have access to comparable equipment.Read 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

The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form ....The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form the double helix. The occurrence of hybridization is determined by differences in surface force measurements compared with when only the single strand of DNA is present. In this way DNA samples can be analyzed without amplification; a major advance for DNA diagnostics.Read moreRead less

Over the last twenty years advanced molecular measurement techniques have enabled the characterization of individual biological molecules (proteins and DNA) within different types of cells and diseased tissues. This project uses a new technique that literally "weighs" groups of proteins and/or DNA to help us understand how such large molecules fit together and function within cells (sometimes referred to as molecular machinery). More detailed knowledge of processes such as those involved in copying DNA when new cells are produced will, in the long term, improve our understanding and treatment of conditions or diseases that result from errors in molecular machinery.
