Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately ....Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately microelectronic engineering methods will be used. This will give control over the attachment process with potential benefits of orienting attaching molecules, minimising non-specific attachment and enriching diagnostics by enabling interrogation of the force of attachment.Read moreRead less
Atomistic mechanisms of the mechanical behaviour of nanostructured silicon carbide films. Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications.

Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications. This project aims to understand the mechanisms behind the exceptional properties in ns SiC and to explore the possibility of realizing the two properties in the same ns SiC. The results obtained from this research will be very important for guiding the structural design of SiC with exceptional mechanical properties which will have a wide range of structural applications.Read moreRead less

Summary
Interaction between silver ions, silver nanoparticles and reactive oxygen species: implication to toxicity. The project investigates the ability of various different (supported and stabilised) types of nanosized silver particles (SNPs) to oxidatively degrade selected contaminants and or kill microorganism. The project also aims to determine the effect of solution condition (for example pH) and light on SNP longevity and hence their oxidative capacity.
Tunable antifouling behaviour on rough surfaces. The impact of subtle variations in nano and micro scale surface roughness on larger scale wetting and antifouling behaviour of surfaces is investigated. This will lead to next generation non-toxic coatings for both medical and marine applications. The environmental implications will be a significant feature of the ongoing assessment of this study.
