Chemical analysis is a vital activity in our society, which is to a large extent confined to scientific laboratories and carried out with complex instrumentation. The breakthrough technology envisioned in this proposal will pave the way for simple, low-cost tests which can be used by non-scientists. The development of small, portable sensors for applications ranging from pollution monitoring to health testing, will enable ordinary people to gain knowledge about the concentrations of molecular compounds in their environments and in themselves. This will stimulate economic and social benefits related to environmental testing and early disease diagnosis and generate new commercial opportunities for the Australian biotechnology industry.Read moreRead less
Gelled electrolyte materials for toxic gas sensing. This project aims to develop and implement an alternative approach to the current methods of monitoring of oxygen and toxic gas levels. The aim is to use novel gelled electrolytes based on ionic liquids and polymers, combined with miniaturised sensor devices, to create a robust membrane-free and spill-less design.

This project aims to develop and implement an alternative approach to the current methods of monitoring of oxygen and toxic gas levels. The aim is to use novel gelled electrolytes based on ionic liquids and polymers, combined with miniaturised sensor devices, to create a robust membrane-free and spill-less design. Amperometric gas sensors are commonly employed to monitor oxygen and toxic gas levels, but the technology used is still based on a 1950s design. The expected outcome of the project is to make fundamental advances in the design of materials that are not affected by humidity changes and which impart selectivity towards particular gases. This will provide the basis for a new generation of low-cost, miniaturised, selective sensors for use in applications such as wearable toxic gas sensors, and as leak detectors on hydrogen-powered vehicles.Read moreRead less

This proposal aims to understand the chemical and physical properties governing the transport of ions into and within advanced extracting polymeric materials, known as polymer inclusion membranes, under the influence of an applied voltage. These membranes are dry-to-touch and represent a new and potentially powerful analytical platform for environmental, medical and industry sample preparation. By understanding the transport mechanism, new membranes will be developed, capable of purifying and concentrating diverse targets chemicals from liquid and solid samples. These processes can take place during sample transportation to a centralised laboratory thus simplifying and streamlining analysis upon arrival to decrease drastically its costs.Read moreRead less

Cracking post-translational modification codes in high molecular definition. This project aims to markedly improve the analysis of post-translational modifications (PTM) via intact protein mass spectrometry. Differences in the PTM forms of a protein (modforms) can be crucial in many physiological and metabolic processes. However, current conventional methods cannot accurately separate nor fully assign most protein modforms. A recent discovery has resulted in the ability to separate whole protein ....Cracking post-translational modification codes in high molecular definition. This project aims to markedly improve the analysis of post-translational modifications (PTM) via intact protein mass spectrometry. Differences in the PTM forms of a protein (modforms) can be crucial in many physiological and metabolic processes. However, current conventional methods cannot accurately separate nor fully assign most protein modforms. A recent discovery has resulted in the ability to separate whole protein ions that have the same mass, charge, and collision cross section, but subtly different charge sites. This project aims to leverage this breakthrough by developing novel approaches for separating intact protein modforms and mapping PTM sites. This is expected to be important for future biological discovery.Read moreRead less

This project aims to significantly improve the analysis of single cells by mass spectrometry with ultrahigh sensitivity. Molecular differences between cells in large populations can be important in many processes, including cell differentiation and signalling. However, most measurements result in the chemical heterogeneity between cells being masked by the bulk population. Recent discoveries now make it feasible to measure thousands of proteins and small molecules from single cells. This project aims to leverage these breakthroughs to allow heterogeneity to be characterised in single cells with unprecedented molecular detail. This is expected to be important for future biological discovery, as well as disease prediction and drug discovery.Read moreRead less
