Evidence that nanoparticles in sunscreens could be toxic if accidentally eaten (4/8/2010)

Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death. ...> Full Article

Nanoparticles used in common household items caused genetic damage in mice (11/25/2009)

Titanium dioxide nanoparticles, found in everything from cosmetics to sunscreen to paint to vitamins, caused systemic genetic damage in mice, according to a comprehensive study conducted by researchers at UCLA's Jonsson Comprehensive Cancer Center. ...> Full Article

Where do nanomaterials go in the body? (11/5/2009)

Tiny, engineered nanomaterials can already be found in many consumer products, and have been hailed as having widespread future uses in areas ranging from medicine to industrial processes. However, little is known about what happens if these nanomaterials get into your body -- where do they go? NC State researchers are working to answer that question under a grant from the National Institutes of Health. ...> Full Article

EPA announces research strategy to study nanomaterials (10/3/2009)

The US Environmental Protection Agency today outlined a new research strategy to better understand how manufactured nanomaterials may harm human health and the environment. The strategy outlines what research EPA will support over the next several years to generate information about the safe use of nanotechnology and products that contain nano-scale materials. ...> Full Article

Carbon nanoparticles toxic to adult fruit flies but benign to young (8/10/2009)

Researchers at Brown University have discovered that certain types of carbon nanoparticles can be environmentally toxic to adult fruit flies, although they were found to be benign when added to food for larvae. The findings, published online in Environmental Science & Technology, may further reveal the environmental and health dangers of carbon nanoparticles. ...> Full Article
