A surface functionality based approach for the risk assessment of manufactured nanomaterials in the environment. Manufactured nanoparticles are increasingly present in the environment yet their risk assessment is fraught with analytical challenges. This project will use customised nanoparticles with unique isotopic signatures and surface properties to circumvent key difficulties and support novel investigations into nanoparticle stability, fate and toxicity.
Addressing the uncertainties: Pathways, fate and associated risks of manufactured nanoparticles in the environment. Manufactured nanomaterials are increasingly present in commercial products, such as sunscreens, textiles and building materials. Their subsequent release to the environment is unavoidable. This project will deliver novel methods for assessing the associated risks, thereby supporting the safe and sustainable use of nanomaterials in Australia.
Is mass commercialisation of silver-based nanotechnology undermining its biomedical antibacterial potential? Silver nanoparticles have demonstrated broad spectrum antibacterial potential and are increasingly used in biomedical applications to limit infection. They are also found in a growing range of everyday products such as shampoos and socks. This situation is analogous to the previous use of antibiotics for nonmedical purposes and the subsequent spread of antibiotic resistant bacteria. This ....Is mass commercialisation of silver-based nanotechnology undermining its biomedical antibacterial potential? Silver nanoparticles have demonstrated broad spectrum antibacterial potential and are increasingly used in biomedical applications to limit infection. They are also found in a growing range of everyday products such as shampoos and socks. This situation is analogous to the previous use of antibiotics for nonmedical purposes and the subsequent spread of antibiotic resistant bacteria. This project will measure silver resistance selection pressure in key microbial communities. Novel monitoring devices, a multi-technique chemistry approach, and correlative synchrotron spectroscopy and molecular biology techniques will be used to decipher the environmental silver resistome and its likely significance.Read moreRead less
