This map shows the locations (by zipcode) of companies, universities, government laboratories, and organizations working in nanotechnology around the United States.
- Toxicology for the 21st century: an opportunity for nanotoxicology
(June 23, 2011) Nanomaterials are acclaimed for their novel properties. But as properties change, unwanted properties are to be expected as well. Thomas Hartung explains how the innumerous formulations of nanomaterials will change toxicity assessments, including the development of alternatives to animal testing.
- The Science and Safety of Nanotechnology
You don’t have to look far to find nanotechnology at work around you. Nanoparticles – miniscule particles that can measure 1/100,000th the width of a human hair — are in computer components, stink-resistant socks, wrinkle-free pants, toothpaste, and sunscreen. In medicine, nanoparticles are hunting down and attacking cancer tumors. They are being used to purify wastewater and harness the sun’s energy. But some people are questioning the safety of nanotechnology. This hour, a conversation about the science and safety of nanotechnology with ANDREW MAYNARD, the Chief Science Advisor of the Project on Emerging Nanotechnologies at The Woodrow Wilson International Center for Scholars.
- Trips to the Nanofrontier
WASHINGTON, D.C.—Nanotechnology’s many anticipated benefits will arrive in waves of innovation, beginning with today’s stain-resistant clothing and other first-generation applications and extending decades into the future, when extraordinarily advanced products, from self-repairing tissues to quantum computers, may become practical.
Given the incredible promise of the fast emerging field—and the billions in public and private investment that it has attracted—the Project on Emerging Nanotechnologies (PEN) launched today a new series of NanoFrontiers newsletters and podcasts focused on progress toward exciting applications on the horizons of nanotechnology.
- Preventing Adverse Health Effects from Nanotechnology
From smartphones to skincare, there are currently over 1,000 commercial products containing nanomaterials, with applications as far ranging as the fields of medicine, engineering, electronics and energy production. This session of Public Health Grand Rounds focuses on the current state of knowledge in nanotechnology and discusses concerns about the harmful impact that exposure to some nanomaterials may have on humans and the environment.
- Carbon Nanotubes Risks - exposure, chemistry, and physical form
Carbon nanotubes being used to make products stronger, lighter, faster, more efficient. But are they safe? A growing body of research is raising concerns over the hazards presented by some forms of the material. As ever though, the risk to health depends on who is exposed to what and where, and how much they are exposed to. This week's Risk Bites takes a look at factors that may affect how carbon nanotube toxicity is translated into risk.
