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
Bioanalytical Microchips Based on Integrated, Application Tailored Monolithic Modules.

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.

Porous silicon biosensor for rapid detection of water-borne contaminants. We have recently demonstrated the rapid degradation of porous silicon by certain transition metal complexes known as biomimetic catalysts. The catalysed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. Using this mechanism, we will develop a biosensor for the rapid detection of contaminants (toxins etc.) in water resources. Reservoir w ....Porous silicon biosensor for rapid detection of water-borne contaminants. We have recently demonstrated the rapid degradation of porous silicon by certain transition metal complexes known as biomimetic catalysts. The catalysed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. Using this mechanism, we will develop a biosensor for the rapid detection of contaminants (toxins etc.) in water resources. Reservoir water treatment today is reactive rather than preventive because current analysis is slow. Our biosensor can be turned into a field kit to improve water quality management and prevent acts of deliberate sabotage to the water supply.Read moreRead less

Doping control in sport is to protect the health, legal and ethical rights of athletes. The use of banned drugs in competitive sports is becoming increasingly sophisticated and the need to counter this provides a stimulus for ground breaking analytical research.
