Medically used nanoparticles can damage the DNA of cells without crossing cellular barriers in the body. The scientists grew layers of human cells in the lab to mimic a protective barrier – like the bodies blood- brain barrier. They used this barrier to examine the indirect effects of cobalt-chromium nanoparticles – which are generated from [...]

New research shows how the inhalation of carbon nanotubes can suppress the immune function of mice. This finding highlights potential health concerns for those working with these materials. The study to be published on Monday in Nature Nanotechnology shows that inhalation of low levels of nanotubes causes activation and release of a signalling molecule from [...]

An independent review of Australia’s nanotechnology regulation has been conducted by the Centre for Regulatory Studies at Monash University. The Review of Possible Impacts of Nanotechnology on Australia’s Regulatory Framework found that Australia’s regulatory frameworks were generally well suited to the task ahead in regulating nanotechnologies but it identified six regulatory issues which need addressing.
