I must agreed with many of your points, but ill asure you i rarely take info from sale pitch as hard evidence. most company that advertise their so called TEM pictures can only refered to silver particles not iones.. iones in the absent of water oxidises , there for will not show their true form in a picture. diferent aproche need to be taken. can surely apreciated a well founded difference of point of view as yours, indeed the body internal fluids are both colloidal and ionic, iones+ can surely attach to other mineral traces and form new sustances such as chlorine, coper iones, and many more, i have read many or most of the so call comercially available forms of silver, silver salts, proteins, nitrates, sulfadine, and all the silver colliids ,wether ionic, hidrosol, As you finely put it all work... but only differ from the time need it to take action and incapacited the pathogens... as you also put it in vitro in vivo studies are just being done or better yet are being made public. here in mexico our governet doesnt put such a hard resistence or bann on silver products or homepatic remedies, as the actutude of most 1st world country as usa, europe or britain. many many essays, reseach,experiments are being done not only in mexico but other places that confirme the efectiveness of silver ions. i dont just read what google,ask,ping, yahoo results comes up with, i used COPERNINC AGENT PROFESIONAL, is a specific topic and INTEREST WWW SEARCH ENGINE , you can set it to only show results from universitites, health institues, goverment and more .any how this tool was very help full in finding information that sopports and clarifies what you may readily find on google or such places fill with their agenda and misinformation. like you said silver hidrosol is still a silver collid, TRUE but not quiet the same. is like saying purified water is as good as spring water, not quiet the same but related. i`m my own best guiny pig, forgive my english migh be a bit rusty, i must have done extensive reasearch for over 5 months and still reading before taking CS, i just did not agreed with all the misinformation on the more comercial web sites regarding silver solution. as you surely know, is the surface area covered , zeta potential of silver solutions, iones+, that can more rapidily work and be excreded from the body, again this is COLLIDAL CHEMISTRY literature from many parts, although i think that since silver ions combine in the body and most of it is consume and axcreded out, that the remaining silverparticles thant cannot eassyly be excreded out can provide a remnant shield protection on the cells thay attach to. again only speculation from some light reading. i have a family member that works in a university nearby , he has agreed to conduc test on silver colloid, ionic silver, hidrosol silver, since i just dont fully believe the results of such in vivo, in vitro experiments comercially available on the web, i can fully trust this family member to be objective at least in the spirit of true sciencie ill happily share his findings on the groups. thank you the thought stimulation.. namaste.
