Miniaturisation-compatible stationary phases and detection techniques will be developed for microseparation techniques of capillary electrochromatography and chip-based separation systems, and their analytical applications will be investigated. Replaceable stationary phases (RSP) of chromatographic particles suspended in reversible gels will be created by delivering a liquid RSP to the column followed by in situ immobilisation. This approach offers flexibility in optimising a number of parameters of the column and of its use for sample pre-treatment and preconcentration. Pulsed potentiometric detection will be developed for the abovementioned microseparation techniques, combining the advantages of pulsed amperometric techniques with the more universally responding potentiometric detection.Read moreRead less

Enzymatic synthesis of pro-resolution lipid mediators: Towards new therapeutic strategies for inflammatory diseases. Inflammation is a major contributing factor in many diseases, including arthritis, Alzheimer's disease, multiple sclerosis, cardiovascular disease and cancer. It has recently been shown that the resolution of inflammation is an active biological process initiated by lipid mediators.

Inflammation is a major contributing factor in many diseases, including arthritis, Alzheimer's disease, multiple sclerosis, cardiovascular disease and cancer. It has recently been shown that the resolution of inflammation is an active biological process initiated by lipid mediators. The aim of this project is to synthesise and characterise pro-resolution lipid mediators, elucidate the enzyme cascades involved in their biosynthesis and explore their roles in the active resolution of inflammation. This project will provide a fundamental understanding of pro-resolution and anti-inflammatory pathways as well as new therapeutic target molecules for the treatment of inflammatory diseases.Read moreRead less

High resolution liquid chromatography mass spectrometry (Orbitrap) for analyses of polar compounds in biomass, petroleum, potable and reclaimed water. Climate change and human impact can harm sensitive ecosystems, significantly threatening Australian biodiversity and water resources.

Climate change and human impact can harm sensitive ecosystems, significantly threatening Australian biodiversity and water resources. Chemical and biological characterisation of aquatic and terrestrial environments is paramount to assessing and responding to these threats, as well as assisting natural resource utilisation. The high structural polarity of many environmentally occurring organics from biological, petroleum and anthropogenic sources, unamenable to gas chromatographic resolution, can now be accommodated by the advanced organic analytical technology sought in this proposal. This project will enable scholars and young professionals to be skilled in state-of-the-art technology, and prepare quality scientists, ready for employment.Read moreRead less

New Enantiomeric Separation Technologies for Natural Product, Pharmaceuticals and Environmental Pollutant Characterisation.

Enantiomeric characterisation allows evaluation of drug purity for potentially harmful constituents, consumer protection against adulteration of essential oils and natural materials, and study of chemical interactions in biochemical/environmental systems. Chromatograph technologies (GC, HPLC and CE)for enantioseparation are available, however limitations prevent multicomponent characterisation of complete sample mixtures. Critical choices involve: choosing a chiral selector that interacts differentially upon all enantiomers; incorporation of selector into high-efficiency chromatographic systems; application to all target compounds in the sample. We will synthesise novel chiral selectors, incorporate these into new separation columns, apply ultra-high resolution 2-dimensional GCxGC to broad-spectrum chiral analysis of volatile chemical samples.Read moreRead less
