This would enable unprecedented numbers of simultaneous (multiplexed) detection events for time-critical analytical applications such as clinical diagnostics, environmental monitoring and biodefense assays. These assays could be performed on low-cost microfluidic platforms operated by portable consumer devices such as mobile phones. Expected outcomes may provide new capabilities in rapid screening for disease biomarkers, environmental pollutants and bioterrorism agents, using simple, low-cost, portable instrumentation.Read moreRead less

This project aims to develop technology for simultaneous three-dimensional imaging of trace elements and molecules in biological tissues. This technology is an essential analytical and diagnostic advance to uncover latent mechanistic biology and will reveal subtle metabolic interactions between cells. The project will use laser ablation-inductively coupled plasma-mass spectrometry and lanthanide-conjugated probes to map the zinc metabolic pathway in the ageing mouse brain. It is expected to result in a complete imaging solution for quantitative spatial determination of all important elements, co-factors, metabolites and other functional molecules to investigate metabolic pathways which current technologies find difficult or impossible to track. Ultimately this technology is expected to underpin investigations of diseases where trace metal and chemical species dysfunction is implicated.Read moreRead less
Enhancing Selectivity and Detection in Miniaturised Analytical Separation Systems. 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.

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

This project aims to develop and apply novel bioanalytical mass spectrometry-based methods and workflows to illuminate the otherwise hidden structural diversity and molecular complexity of the lipidome. The structure of individual lipids define their specific biological functions. A major requirement of analytical methods employed for lipid analysis on a lipidome-wide scale, therefore, is to enable the detailed structural characterisation of the, potentially, tens of thousands of individual molecular lipid species that may be present within a sample of interest. This project will develop and optimise novel, ultraviolet photodissociation-tandem mass spectrometry methods which will be integrated within an automated lipidome analysis workflow, to enable comprehensive global lipidome profiling and to reveal the structural diversity of lipids involved in fundamental cellular signalling processes.Read moreRead less
