Comments on: A Silver Coating in the Fight Against Microbes http://www.scienceline.org/2008/04/18/tech-heger-silver/ The Shortest Distance Between You and Science Thu, 11 Mar 2010 13:02:11 -0500 http://wordpress.org/?v=2.8.4 hourly 1 By: Cal Baier-Anderson http://www.scienceline.org/2008/04/18/tech-heger-silver/comment-page-1/#comment-1692 Cal Baier-Anderson Tue, 29 Apr 2008 21:45:24 +0000 http://scienceline.org/2008/04/18/tech-heger-silver/#comment-1692 The claim made by chemists Lucia and John in this article that bacterial resistance to nanosilver is not possible is dangerously false. There is ample evidence that resistance to silver has developed in several different bacterial genera, including in hospitals.

After seeing the way people die in hospitals due to infections caused by super bugs (today)this is great news! Dr. J. Semo Brilliant!

Many types of bacteria live in lakes and streams, and if silver nanoparticles were to get into the water system they could disrupt the aquatic ecosystem." Why after all of this time experimenting with nature do we think things still "could" have an effect? We are all carrying around numerous metals, chemicals and pesticides in our body. We will be carrying around nano particles as well. And they will be in our streams. “Hu says what concerns him the most is the effect silver nanoparticles could have on aquatic organisms.

Duh. Rupture the bacterium there inside the hospital, it dries up, the DNA blows around or gets tracked out on someone's shoes and scatters til some other bacterium consumes it, and incorporates whatever resistance it had. Great mechanism for transferring resistance. Much better than just washing the bacteria down the sink into the sewage system where they couldn't spread as easily. You have to wonder who benefits from this kind of stuff. Yeah. Duh.
