Dirty hands can spread the germs that cause numerous diseases, and these diseases sicken millions worldwide each year. Current hand hygiene practices involve washing with soap and water and using antiseptic hand rubs, but both methods have drawbacks.…

Could a nanofiber help fight the obesity epidemic?

July 13, 2018 — You won’t smell it. You won’t taste it. And you certainly won’t see it. But a nanocellulose material derived from all-natural substances could potentially become a food additive that reduces fat digestion and absorption…

New Center to assess safety of engineered nanomaterials

August 16, 2016—Engineered nanomaterials (ENMs)—which are less than 100 nanometers (one millionth of a millimeter) in diameter—can make the colors in digital printer inks pop and help sunscreens better protect against radiation, among many other applications in industry and…

Laser printing has gone ‘nano’ — but is it safe?

Researchers recommend that laser printers be kept in well-ventilated areas August 11, 2015 — Manufacturers of toner used in consumer laser printers and other printing equipment are incorporating engineered “nano” materials into their formulations to improve quality. It’s…

Food microbes beware: It’s raining nanobombs

Fighting bacteria with nanotechnology

Nanoparticles with microbial properties have proven effective in fighting bacteria; however, some may cause health risks to humans such as damage to the lungs. But now, researchers at Harvard School of Public Health (HSPH) have developed a technique…

The nano state

[ Spring 2014 ] Can tiny engineered particles help protect us from infectious disease? Hotel rooms, subway cars, offices, airplanes, cruise ships: to most people, the air they breathe inside these places seems benign, if sometimes stuffy and stale. But…

Safer nanoparticles for safer sunscreens

Zinc oxide nanoparticles are used in sunscreens to make them less opaque and more appealing to consumers. But the potential adverse health effects of using nanoparticles in these and other products have not been fully explored, according to…
