Latest Nanotoxicology Stories
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.
University of Pittsburgh researchers have developed the first natural, nontoxic method for biodegrading carbon nanotubes, a finding that could help diminish the environmental and health concerns that mar the otherwise bright prospects of the super-strong materials commonly used in products, from electronics to plastics.A Pitt research team has found that carbon nanotubes deteriorate when exposed to the natural enzyme horseradish peroxidase (HRP), according to a report published recently in...
By Valenzuela, Stella Cortie, Michael Gold nanoparticles can target and kill the parasite Toxoplasma gondii, opening the way for a new treatment for parasitic infections in humans. Over the ages, people worldwide have revered gold as a precious metal, with its uses being many and varied.
By Allison M Heinrichs Potential ecological hazards of nanoparticles will be explored by a $14.4 million partnership between Carnegie Mellon and Duke universities, officials said today. The National Science Foundation and the U.S.
U.S. scientists say they've discovered quantum dot nanoparticles can penetrate skin if there's an abrasion, raising new nanotechnology safety concerns.
A major study published today in Nature Nanotechnology suggests some forms of carbon nanotubes â€“ a poster child for the â€œnanotechnology revolutionâ€ â€“ could be as harmful as asbestos if inhaled in sufficient quantities.
By Nohynek, Gerhard J; Lademann, Jrgen; Ribaud, Christele; Roberts, Michael S Many modern cosmetic or sunscreen products contain nano-sized components.
By Rohner, Fabian; Ernst, Frank O; Arnold, Myrtha; Hilbe, Monika; Et al Abstract Particle size is a determinant of iron (Fe) absorption from poorly soluble Fe compounds. Decreasing the particle size of metallic Fe and ferric pyrophosphate added to foods increases Fe absorption.
The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries lifeâ€™s genetic instructions, DNA, a team of researchers at the U.S. Department of Energyâ€™s Brookhaven National Laboratory recently found.
Researchers have found a way to target cancer cells by injecting tiny particles that will attack only the diseased cells while leaving healthy cells unscathed, according to a study released on Monday.
