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.

This project aims to elucidate the important phenomena of bacterial resistance to antimicrobial nanosilver, currently one of the most developed and commercialised products of nanotechnology. The integrated research approach comprises of concurrent identification of the origins and routes of nanosilver toxicity in bacteria and the arising emergence and mechanisms of bacterial defence to the toxicity. The generated knowledge is to form a base template for novel nanosilver engineering with less tendency for resistance development and to facilitate tracking of resistance and its spread amongst microorganisms. The knowledge has far-reaching implications on the better governance of nanosilver use, including its disposal.Read moreRead less

The project aims to understand how the globally significant mixed-species growth of pathogens develop resistance to silver nanoparticle, currently one of the most important alternative antimicrobials to antibiotics. The integrated research is to elucidate, for the first time, the nanoparticle multi-targeting toxicity on mixed-species bacterial community and how, in turn, the bacteria activate their cell-to-cell signalling for a synergistic defence to adapt to the nanoparticle toxicity. The pioneering knowledge is the foundation for technologies targeting the interspecies metabolite cross-talking to overcome the resistance phenomena, ensuring a long-term efficacy of the alternative antimicrobial on the difficult-to-control pathogenic growth.Read moreRead less

The project aims to develop a titanium dioxide (TiO2) semiconductor that can use full-spectrum solar energy. Solar-driven photocatalytic processes have important applications in water decontamination and energy production. Their effectiveness is dictated by the semiconductor’s absorbance and conversion of photoenergy to chemical energy. Being inexpensive, chemically and mechanically robust, TiO2 is the most promising material for the semiconductor. However, unmodified TiO2 only absorbs ultraviolet light (5 per cent of solar energy). With current progress made in visible absorbance, this project aims to significantly improve TiO2’s absorbance in near infrared by doping with upconversion lanthanides and rendering colloidal crystal suprastructures that can trap light.Read moreRead less
