Comments on: Studying environmental impacts of nanoparticles using mesocosms http://www.foresight.org/nanodot/?p=5542 examining transformative technology Wed, 03 Apr 2013 18:23:47 +0000 hourly 1 http://wordpress.org/?v=3.0.4 By: Stephanie C http://www.foresight.org/nanodot/?p=5542#comment-1369675 Stephanie C Mon, 04 Mar 2013 23:51:43 +0000 http://www.foresight.org/nanodot/?p=5542#comment-1369675 Precisely the right kind of scrutiny, and details about the experimental procedures, results, and interpretations can be found in the journal article. The aspects highlighted in the post center on the experimental design, which allows for realistic exposure scenarios - a requisite for useful data regardless of particle size regime. Regarding possible toxicological effects due to particle size, data pools are slow to emerge (note the broad research objectives of CEINT and the UC CEIN). There are a number of review articles that discuss responsibly why the nanoscale causes concern and the limitations of existing data, for example Seaton 2010: http://intl-rsif.royalsocietypublishing.org/content/7/Suppl_1/S119.full Precisely the right kind of scrutiny, and details about the experimental procedures, results, and interpretations can be found in the journal article.

As you must know, colloidal silver is a potent antibiotic. Silver nitrates are considered hazardous wastes. What has this study proven other than to confirm what we already know?
