A new approach is proposed for the development of novel micro- and nano-scale solid-phase adsorbent materials. These materials are based on porous polymer monoliths formed in situ within a capillary acting as a mould. The allows the material to be readily placed in a defined position, in a process similar to photo-patterning, and alleviates many of the problems usually associated with fabrication and miniaturisation. A simple photo-grafting process, initiated by UV light can be used for the selective chemical modification of these materials. These tailored monoliths can then be used for the in-line coupling of biological sample handling and capillary electrophoresis (CE) for the determination of drugs and related metabolites in biological fluids, thus avoiding time-consuming and costly off-line sample pre-treatment. This will lead to the development of new methods for the rapid determination of drugs, metabolites and other small molecules in clinical samples.Read moreRead less

Microfluidic devices offer substantial advantages over current technology, in terms of speed, cost of analysis, portability, operator simplicity and safety. Integrating multiple analytical processes within a simple and reliable portable device will lead to application in a range of areas, from pharmacology to therapeutic drug monitoring, proteomic and metabolomic screening for disease diagnosis and drug development, and also for performing clinical diagnostics in a rural area. This will significantly impact on the quality of life of the Nation as a whole, not only due to expedient diagnosis and treatment which has obvious health benefits, but also in the considerable financial benefits that result from early and efficient treatment.

Solid-state light sources for bio-imaging and microfluidics. Solid state light sources are the light sources of the 21st century. This project will allow us to find new ways of bioimaging in living organisms applicable to diagnosing disease, and for microfluidic chip based portable instruments for on-site and point-of-care analysis in medical diagnostics, environmental monitoring, and manufacturing processes.
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. 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 ....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. 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
Novel approach to study mechanisms of Na+ transport in plants using Lab on a Chip technology. A Lab on a Chip for sodium ion measurements in plants is proposed, offering a long overdue solution to the lack of appropriate techniques to study the mechanisms of sodium iron uptake, transport and compartmentation. Sodium ion transport is a key determinant of salt tolerance, but a good understanding of its transport mechanisms is lacking since no appropriate measurement tools are available. Using the ....Novel approach to study mechanisms of Na+ transport in plants using Lab on a Chip technology. A Lab on a Chip for sodium ion measurements in plants is proposed, offering a long overdue solution to the lack of appropriate techniques to study the mechanisms of sodium iron uptake, transport and compartmentation. Sodium ion transport is a key determinant of salt tolerance, but a good understanding of its transport mechanisms is lacking since no appropriate measurement tools are available. Using the system proposed here, sodium ion is separated from interfering ions, allowing fast and selective measurements. A series of ground breaking studies towards sodium ion uptake, transport and compartmentation in plants will be conducted using this Lab on a Chip.Read moreRead less
