Developing next-generation mass spectrometry imaging with isomer resolution. Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples. This project will bring together market-leading MSI instrumentation from the industry partner Waters Corporation with unique technologies developed at QUT and UOW to develop an integrated MSI-platform capable of achieving high mass- and spatial-resolution, as well as discrimination of lipid iso ....Developing next-generation mass spectrometry imaging with isomer resolution. Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples. This project will bring together market-leading MSI instrumentation from the industry partner Waters Corporation with unique technologies developed at QUT and UOW to develop an integrated MSI-platform capable of achieving high mass- and spatial-resolution, as well as discrimination of lipid isomers. Resolution of lipid isomers using this instrumentation will afford researchers a first glimpse of isomer-resolved images that will be used to visualise tissue-specific changes resulting from underlying chemical, physical or metabolic processes; changes that are currently invisible to contemporary imaging technologies.Read moreRead less
Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of cer ....Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of certain lipids to ionise with a polarity that affords sensitive detection but does not permit detailed structure elucidation. This project will develop advanced instrumentation capable of on-demand polarity switching of ionised lipids such that the detection and interrogation of molecular structure can take place in the optimal charge state.Read moreRead less

Summary
Deconstructing molecular self-assembly by advanced mass spectrometry. This project aims to develop ion-mobility mass spectrometry methods to observe the molecular evolution of model self-assembly reactions with high temporal and structural resolution, and interrogate the intrinsic gas phase functionality of the assemblies themselves, including aggregation, inclusion and disassembly behaviours. Lack of knowledge of reaction intermediates, mechanisms and kinetics hampers the industrial potential o ....Deconstructing molecular self-assembly by advanced mass spectrometry. This project aims to develop ion-mobility mass spectrometry methods to observe the molecular evolution of model self-assembly reactions with high temporal and structural resolution, and interrogate the intrinsic gas phase functionality of the assemblies themselves, including aggregation, inclusion and disassembly behaviours. Lack of knowledge of reaction intermediates, mechanisms and kinetics hampers the industrial potential of self-assembly to fabricate highly functional materials. This project expects to determine the critical link between the assemblies’ structure and function, and provide the rational framework to optimise and direct synthetic outcomes. This could enable Australian manufacturers to create low-energy production processes of high value commodities.Read moreRead less
