New nano skin penetration findings demand TGA close legal gaps

Macquarie University’s Professor Brian Gulson reported last week that isotope-labelled zinc from nano-sunscreens penetrates healthy adult skin and reaches the blood stream and urine of human test subjects. The study results undermine the Therapeutic Goods...

Nanoparticles cause DNA damage – without even entering cells

New researched published in Nature Nanotechnology shows that nanoparticles can damage DNA and chromosomes in cells, across an intact barrier of other cells. The research suggests that nanoparticles could cause cancer, or even birth defects, without crossing biological...

A link between nanoparticles and Alzheimer’s disease?

AzoNano reports that scientists at the University of Ulster are investigating a link between manufactured nanoparticles, such as titanium dioxide found in sunscreens and cosmetics, and Alzheimer’s disease. Exposure to some nanoparticles can cause proteins to...
