For the first time, research shows that nanoparticles called fullerenes are filtered out of water by oysters and taken up by their liver cells.
Fullerenes may cause long-term health problems in oysters and reduced survival and reproduction. 16 November 2009. More...
Iron nanoparticles that are poised for use in large-scale pollution remediation can rapidly react with oxygen and cause lung cells to die.
The same qualities that make these particles potentially useful in environmental clean-up -- their high reactivity -- also make them potentially harmful to living things. Some of the reactions can release free radicals that can damage cell DNA. 12 August 2009. More...
A nanomaterial prized for its potential use in electronics moved through human lung fluid and altered the way lung cells reacted to infections, possibly reducing their ability to signal immune defenders and fight off the invaders.
The results add more concern about the safety of the very tiny particles called single-walled carbon nanotubes (SWCNT). Workers who make the materials -- and consumers who use them -- may be at risk if the nanomaterials are inhaled. 6 March 2009. More...
Iron-containing nanomaterials can cause inflammation and other cell damage if it touches skin, conclude the researchers who tested the particles on engineered skin, human skin cells and mice skin.
The particles may be a health risk for workers who make or use the tiny single-walled carbon nanotubes (SWCNT), as well as consumers of the final products that contain them. Development of new electronic devices, circuits and computers using these particular materials is underway. 11 February 2009. More...
Catching a ride on nanoparticles is a newly discovered way for harmful substances to get inside living cells.
While health effects in people are not yet known, the cell injury reported in this new study from Europe raises concern for workers who make the nanoparticles and consumers who use them. 7 January 2009. More...
A single exposure to carbon-based nanomaterials can damage DNA in a rat's sensitive liver and lung tissue, raising health concerns for people exposed through work and consumer products.
Danish researchers report that very small carbon particles, called fullerenes, and elongated tubes of carbon, called nanotubes, can enter mammalian cells and damage their DNA. The type of damage caused can lead to cancer. 23 December 2008. More...
The smaller the size, the more damage silver nanomaterials will cause, according to research with cells from the lungs of rats.
Use of silver nanomaterials is increasing rapidly in common in consumer products, even though scientists have barely begun to study the risks. 21 November 2008. More...
Scientists have shown for the first time that nanoparticles of titanium dioxide can travel from the nose to the brain and cause damage to brain cells in laboratory mice.
The nanocompound is a white pigment widely used in paints, coatings, plastics, cosmetics, sunscreens and other personal care products. These results suggest that short-term exposure to nano-sized titanium dioxide via breathing could lead to brain injuries. 17 November 2008. More...
A study using cells and rats shows that nanoparticles of aluminum oxide can kill and adversely change the special cells that line the blood vessels in the human brain.
The rapid increase in production and use of these very, very small particles will inevitably increase human exposure to the as yet unknown risks from these materials. 21 October 2008. More...
A new study from Sweden finds that several nanomaterials--now widely used in sunscreens and other consumer products--can damage the DNA of human lung cells.
The researchers exposed human cells from the surface of lungs to eight different types of nanomaterials and measured DNA damage and indicators of stress. The findings highlight the urgent need for proper testing of these small particles to understand the health risks associated with each type of material. 7 October 2008. More...
