Summary
Unravelling the intrinsic structure and stability of multiply charged anions in the gas-phase using photoelectron spectroscopy and mass spectrometry. Molecules possessing multiple negative charges are common constituents in chemistry, influencing a range of processes ranging from photochemical smog formation to protein structure in vivo. This project will develop new technologies to probe their molecular structure in the gas-phase, leading to a more rigorous understanding of these species.
Rapid, ultra-sensitive protein structure elucidation by mass spectrometry. This project seeks to develop a method for rapidly discovering classes of molecules that bind to unique sites on proteins. The development of new pharmaceuticals is frequently delayed by the time and resources required to identify the sites that new chemical entities bind to protein targets. A recent discovery has resulted in the ability to completely characterise large protein sequences directly from single mass spectra. ....Rapid, ultra-sensitive protein structure elucidation by mass spectrometry. This project seeks to develop a method for rapidly discovering classes of molecules that bind to unique sites on proteins. The development of new pharmaceuticals is frequently delayed by the time and resources required to identify the sites that new chemical entities bind to protein targets. A recent discovery has resulted in the ability to completely characterise large protein sequences directly from single mass spectra. This project aims to leverage this breakthrough by developing a rapid new approach for revealing ligand-protein binding sites using whole-protein mass spectrometry. This would enable novel sites of interactions between molecules and protein targets to be discovered rapidly with high sensitivity. In turn, this would allow the efficient design of next-generation classes of bioactive molecules.Read moreRead less
New laser and mass spectrometry-based tools for comprehensive structural elucidation of lipids and their biomolecular interactions. Lipid-related disorders such as obesity, diabetes and heart disease are reaching epidemic proportions. We propose the development of specialised instrumentation to identify and quantify lipids (fats) in tissue and culture samples thus providing Australian scientists with unique capabilities to investigate the mechanisms of disease.

Summary
Multiplexed capabilities for surface analysis and imaging by mass spectrometry. This facility will support research aimed at developing rapid and reliable analytical methods for the detection of chemicals directly from biological and man-made materials. The mass spectroscopy methods used at the facility will reveal molecular-level changes in systems ranging from the lens of the human eye to Colorbond steel® and have applications in the detection of chemical and biological hazards.
The photons take charge: Elucidating the structure and stability of distonic radical anions by mass spectrometry and photoelectron spectroscopy. Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties.

Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties. This project will probe the fundamental structure and energetics of radical anions by modifying instrumentation to enable multi-step gas-phase ion synthesis to be efficiently coupled with anion photoelectron spectroscopy. These investigations are essential to revealing the scope of this phenomenon in free radical chemistry and biology and could inform future development of new catalysts for polymerisation.Read moreRead less

Lasers are indispensable tools for the characterization and photochemical modification of molecular systems. Powerful lasers produce intense bursts of light across the electromagnetic spectrum, from the infrared to the ultraviolet. This versatility allows chemists to observe the dynamical behaviour of single molecules on ultra-fast timescales, to probe the shape of molecules relevant to the action of therapeutic drugs, to explore the characteristics of molecules found in space, and to initiate laser-activated chemical processes in microscopic dimensions to modify sensor surfaces. The proposed laser facility will enable progress in these areas and will help maintain Australia's research edge in nanotechnology and biotechnology.
