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

Summary
Certain engineered nanomaterials are more toxic than their bulk material forms. We urgently need the ability to re-engineer these nanomaterials to reduce their toxicity and potential health risks, but lack the necessary knowledge. This project directly addresses the NHMRC Strategic Initiative on Nanotechnology and Health, by providing essential information for designing safer nanomaterials from systemically studying the immune effects of metal oxide nanoparticles used in Australian industry.
Properties of nanomaterials determine their disposal by liver cells. This project aims to understand how the liver handles and is affected by nanomaterials in the body. Nanomaterials are widely used in industrial, environmental, consumer and drug products, but how they affect human health is poorly understood. This project will characterise the spatiotemporal distribution of a set of nanomaterials with defined attributes in naïve and modified livers using chemistry, imaging and biological method ....Properties of nanomaterials determine their disposal by liver cells. This project aims to understand how the liver handles and is affected by nanomaterials in the body. Nanomaterials are widely used in industrial, environmental, consumer and drug products, but how they affect human health is poorly understood. This project will characterise the spatiotemporal distribution of a set of nanomaterials with defined attributes in naïve and modified livers using chemistry, imaging and biological methods. This work is expected to determine how nanomaterials’ attributes direct pathways for liver cell disposal and describe nanomaterial–liver interactions at the cellular level, information crucial in enabling safer nanomaterials for use in products such as drug formulations, sunscreens and cosmetics.Read moreRead less
