"High chemical reactivity of Ag nanoparticles was observed in the reaction with hydrochloric acid: Ag (nanoparticles) +HCI -> AgCl + H-2; the reaction product silver chloride was characterized by X-ray powder diffraction to give a direct evidence for the reaction which has been proved impossible for the bulk Ag." - Steve N From: David AuBuchon [mailto:[email protected]] Sent: Tuesday, September 21, 2010 11:05 AM To: [email protected] Subject: Re: CS>CS and killing of pathogens Hey Steve, I had been wondering that. It seemed strange to me that it was automatically assumed that particles could get by the stomach acid untouched, as if it was self evident. If you have any info on that, I would like to have it. Thanks, ~David You have probably read the claim by some suppliers of particle based CS that ionic silver is not effective and that only silver particles are active. And that the effectiveness of particle silver is dependent on the total surface area if the silver particles. It turns out that nothing is further from the truth. A fairly recent study has shown that stomach acid is highly reactive with silver nanoparticles and converts the silver nanoparticles the same as it does ionic silver. If the silver particles are large enough some of the particle may escape conversion but the same would be true of the silver particles in CS generated by electrolysis. - Steve N
