Peter Fielden's research is focused on Analytical Science – the
quantitative measurement of chemical and biochemical species in a
diversity of environments. Sensors and sensing systems based on
electroanalysis enable the detection of very low concentrations of metal
ions in solution through to process monitoring in water treatment.
Electrokinetic separation systems, with a special emphasis on the
technique of isotachophoresis, have been applied to a diverse range of
measurement challenges. Such sensing and separation systems may be
integrated with microfluidics and lab-on-a-chip devices. The fabrication
of micro and nanostructures in polymers has enabled the development of a
range of lab-on-a-chip measurement systems. Microfluidics has been
applied to the generation of concentration profiles through fluidic
resistor networks, and also to the generation of multiphase
microfluidics (droplets) for very high-throughput analysis. This
approach has is being applied to drug discovery, formulation and
life-science research.
