A new study raises the possibility that flies and other insects that encounter nanomaterial "hot spots," or spills, near manufacturing facilities in the future could pick up and transport nanoparticles on their bodies, transferring the particles to other flies or habitats in the environment. The study on carbon nanoparticles "” barely 1/5,000th the width of a human hair "”is scheduled for the Aug. 15 issue of ACS' Environmental Science & Technology, a semi-monthly...

Nanoparticles of titanium dioxide, used in air and water purification and self-cleaning surfaces, cause brain dysfunction in mice, a Japanese study indicated. The findings add to the current concern that this specific nanomaterial may have the potential to affect human health, Tokyo University of Science researchers said. The researchers, led by pharmaceutical sciences Professor Ken Takeda, said genes affected by titanium dioxide nanoparticles are associated with childhood disorders such as...

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nano-particles. This is the conclusion drawn at the close of Empa's 3rd NanoConvention, held on July 6th in Zurich and attended by...

Singaporean scientists say they have developed nanoparticles that might lead to new treatments for meningitis, fungal infections and drug-resistant bacteria. Scientists at the Institute of Bioengineering and Nanotechnology of Singapore said the stable bioengineered peptide nanoparticles effectively seek out and destroy bacteria and fungal cells that could cause fatal infections. The scientists said their nanoparticles contain a membrane-penetrating component that enables them to pass through...

Scientists have now revealed how nanoparticles can cause lung damage. In the same research, they reported successfully being able to block the cancer-causing mechanism. Nanotechnology is a growing sector of research that involves the control of atoms and molecules to create new materials, including many that could have medical applications. Nanotechnology, as an industry, is expected to gain an annual market of about $1 trillion by 2015, researchers said in the June 11 issue of the Journal of...

Using aquatic microbes as their "canary-in-a-cage," scientists from Ohio today reported that nanoparticles now being added to cosmetics, sunscreens, and hundreds of other personal care products may be harmful to the environment. Their report was part of symposia that included almost two dozen papers at the 237th National Meeting of the American Chemical Society where scientists grappled to understand the environmental and human health effects of nanotechnology. Hundreds of products utilizing...

Owing to the novel properties of carbon nanotubes (CBNs), a series of problems associated with in vitro toxicity assessments of carbon nanotubes (CNTs) have appeared in many literatures. In order to properly evaluate the potential risk to human health, the cell toxicity assay of CBNs can not be conducted by traditional methods employed in common toxicology. Ying Zhu and Wenxin Li in Laboratory of Nano-biology and Medicine, Shanghai Institute of Applied Physics, Shanghai, P. R.China gave this...
