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

A new approach is proposed for the design and synthesis of functionalised ion-exchange stationary phases for analytical nano-separation methods. Desired charged functional groups are first affixed chemically onto nanometre sized latex particles and these particles are then self-assembled mechanically as monoloayer coatings onto a suitable supporting template such as fused silica, monolithic silica or polymer beds, microfibres or microtubes, and channels in microchips. The resultant coated surface then acts as a highly efficient ion-exchange stationary phase which will be used in a wide range of separation technologies including ion chromatography, capillary electrophoresis, capillary electrochromatography and solid-phase microextraction.Read moreRead less
Microreactors for Organic Synthesis. Since the electronic revolution, miniaturisation has been the trend for devices from consumer electronics to scientific instruments. In this time very little has changed in the manner, or scale, that synthetic organic chemistry has been carried out even though advances in instrumentation mean that less compound is required for identification and analysis.

Since the electronic revolution, miniaturisation has been the trend for devices from consumer electronics to scientific instruments. In this time very little has changed in the manner, or scale, that synthetic organic chemistry has been carried out even though advances in instrumentation mean that less compound is required for identification and analysis. This project aims to bridge the gap by developing recyclable miniaturised reaction vessels for the formation of organic compounds on a scale thousands of times smaller than it is currently done. These devices will have applications in drug discovery programmes due to higher throughput and increased efficiency while minimising waste.Read moreRead less

Due to the way in which multiple processes are integrated in a micro Total Analysis System (µTAS), they offer substantial advantages over current technology, in terms of speed, cost of analysis, portability and operator simplicity and safety. This has considerable potential benefit for Australia, specifically for the remote and rural analysis of drugs and metabolites in biological fluids such as blood, serum, urine and saliva. These devices will have application for point-of-care testing in therapeutic drug monitoring, which will improve medical treatment and the patient's quality of life, as well as for on-site analysis in forensics for the rapid determination of illicit drugs and performance enhancing substances in our elite athletes.

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
