Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.
Xylem Inc., a leading global water technology company focused on addressing the world’s most challenging water issues, congratulates Anirudh Jain of Portland, Oregon on his selection as the 2013 winner of the United States Stockholm Junior Water Prize (SJWP) – the world’s most prestigious youth award for water-related science and technology projects.
BASF has participated in a research project by BMBF (German Federal Ministry of Education and Research) about the safety effects of nanoparticles. The results of the project will allow faster and easier evaluation of nan...
Professor Dr M. N. V. Ravi Kumar and Dr Dimitrios Lamprou, of the Strathclyde Institute of Pharmacy and Biomedical Sciences, believe an advanced form of atomic force microscopy, known as PeakForce QNM, could boost developments in the field of nanomedicines, the encapsulation of potent drugs in tiny particles measuring billionths of a meter in diameter. They described how this detailed imaging approach may also help scientists address growing concerns in the medical world around "nanotoxicology", the build-up of microscopic particles in people's tissues.
For the first time, researchers from institutions around the country have conducted an identical series of toxicology tests evaluating lung-related health impacts associated with widely used engineered nanomaterials (ENMs).
A Multidisciplinary team at Trinity College Dublin from the School of Medicine and CRANN, the Science Foundation Ireland funded nanoscience institute, has developed a new screening approach to test the safety of nanomaterials and their effects on human cells.
Earlier efforts to determine the health and environmental effects of the nanoparticles that are finding use in hundreds of consumer products may have produced misleading results by embracing traditional toxicology tests that do not take into account the unique properties of bits of material so small that 100,000 could fit in the period at the end of this sentence.
For his doctoral dissertation Niskanen has been studying several hybrid nanomaterials, i.e. combinations of synthetic polymers and inorganic (gold, silver and montmorillonite) nanoparticles. He will defend his doctoral t...
In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.

Researchers at Syracuse University's Department of Biomedical and Chemical Engineering at L.C. Smith College of Engineering and Computer Science are studying the toxicity of commonly used nanoparticles, particles up to one million times smaller than a millimeter that could potentially penetrate and damage cell membranes.
