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 an industry partner, Waters Corporation, with unique technologies developed at QUT to develop an integrated MSI-platform capable of achieving high mass-resolution 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 characterisation of biomass burning smoke particles using Electrospray-Orbitrap mass spectrometry

Australian bushfires and prescribed biomass burning (BB) have a significant impact on both human health as well as global and regional climate.While emissions from traditional sources, such as vehicles and power plants are expected to decline due to more stringent regulations, air pollution from BB smoke is expected to continue growing.The impact of BB smoke particulate matter on human health will depend on their chemical and physical properties. However, that information for smoke from Australian ecosystems is very limited.The aim …

Production of medicinal compounds from mushroom species cultured in solid state fermentation

Australia generates thousands of tonnes of organic waste residues related to agriculture (e.g. sugar and cotton industries). These are generally unsuitable as bacterial growth substrates, but can be utilised by fungi.Fungi have developed an array of enzymes that allow them to access cellular building blocks and energy stored in recalcitrant carbon or ligno-cellulosic/hemi-cellulosic waste material.The aim of this project is to harness the fungi’s ability to access this carbon and generate fungal biomass (mycelia and fruiting bodies) that contain medicinal …

Smoke and mirrors: intercepting the elusive molecular precursors of soot

Air pollution is set to become the major environmental cause of premature death. In Australia, airborne smoke particles from anthropogenic and natural sources, including bushfires, present a particular risk to the population’s health. Despite its national importance, the fundamental chemical transformation of hot gases released during combustion to soot particles is poorly understood. In the absence of a chemical model for these gas-phase reactions it is challenging to predict or control the composition and concentration of particles released into the …

Pluses and minuses of lipid mass spectrometry

Lipids (fats) are an abundant and structurally diverse group of molecules with an equally diverse array of functions in cellular biology.This project will develop new analytical technologies - based on advances in mass spectrometry and ion chemistry - that enable the analyst to identify and quantify individual lipids present at low concentrations in biological mixtures comprising many thousands of distinct molecules.These new capabilities will drive the discovery of unknown lipids and map the complex biochemical pathways through which they are …

Online aerosol chemical characterisation using Particle Into Liquid Sampler coupled to Electrospray Ionisation Orbitrap Mass Spectrometry

Atmospheric aerosols are important as they have impact on earth’s climate and human health.Organic components represent a significant fraction of atmospheric aerosols. They can be directly emitted in the atmosphere or formed in the atmosphere by oxidation of gaseous precursors.Real-time characterisation of organic aerosol is required to understand their sources, formation and ageing (change) in the atmosphere.There are several mass spectrometry techniques currently used for real-time characterisation of organic aerosols. However, the techniques use hard ionisation, resulting in molecular fragmentation, …

Laboratory simulation of Secondary Organic Aerosol (SOA) formation

This project aims to investigate the interaction of anthropogenic (human-made) emissions and biogenic emissions from plants and trees and subsequent secondary organic aerosol (SOA) production in urban environments. This is relevant as SOA is part of particulate matter (PM), which is associated with smog events in cities, affects the climate and has negative impacts on human health.SOA is formed in the atmosphere by complex reactions of volatile organic compounds (VOCs) of anthropogenic or biogenic origin with atmospheric oxidants (OH radicals, …

Precursors of atmospheric aerosols in the Southern Ocean and Antarctica

Atmospheric aerosols are tiny liquid or solid particles suspended in air. They have a significant role in the radiative balance through their direct interaction with incoming solar radiation (scattering and absorption), and indirectly through their interactions with cloud (they act as seeds on which water can condense to form clouds).Indirect effect is a much more complex problem, and involves the role of aerosols in the cloud formation and the modification of their properties such as changes to cloud reflectivity, cloud …
