At its June 22, 2007, meeting, the National Toxicology Program’s (NTP) Board of Scientific Counselors (BSC) reviewed nominations of several substances for testing, including nanoscale silver. The Food and Drug Administration nominated nanoscale silver for toxicological studies “based on (a) increasing widespread use in drug, food and cosmetic products, and (b) the general lack of data on the toxicology and pharmacokinetics of these materials.” Comments on the...

Nano-Bio Interaction Workshop Materials Available
The International Council on Nanotechnology (ICON) held a workshop entitled “Towards Predicting Nano-Bio Interactions” on June 5-7, 2007. The plenary presentations and meeting information are now online....
EHP-in-Press published an article entitled “Persistent Tissue Kinetics and Redistribution of Nanoparticles, Quantum Dot 705, in Mice: ICP-MS Quantitative Assessment.” The purpose of the study was to assess the tissue disposition and pharmacokinetics of quantum dots (QD705) in mice. According to the article, the plasma half-life of QD705 in mice was short (18.5 hours), but analyses revealed QD705 persisted and even continued to increase in the spleen, liver, and kidney 28...
