====================== Thanks for the link. Here is a short quote from the article: ===beginning of quoted portion=== Microorganisms Can Develop Resistance to Nano-silver. Before the dramatic increase in application of silver nanoparticles as an antimicrobial, ionic silver has had a long history of use as a disinfectant. Many reports frequently use the term " silver" when referring to silver ions. Decades-old discoveries provide evidence on the potential of microorganisms to develop resistance to chemical species of silver that are cytotoxic, so that the microorganisms continue to grow even in the presence of silver. One of the earliest reports of antimicrobial resistance to silver ions was by Jelenko et al. in 1969. The study isolated resistant Escherichia coli from a clinical case of prolonged silver-nitrate-treated burns (detected at day 47, following treatment with 0.5% silver nitrate at day 1 and day 36 postburn). This finding was followed by the discovery of a silver-resistant Salmonella typhimurium strain in the 1970s, also isolated from clinical cases of silver-nitrate-treated burns (detected as early as day 8, following treatment with 0.5% silver nitrate). The isolated strain was later characterized as having nine resistance determinants, known as the sil genes. Examples of bacteria adapting to conditions of long exposure to silver are also found outside the clinic, in specific environmental settings " where toxicity might select for resistance" a quote from A. Gupta and S. Silver, 1998), including the soil of a silver mine and photographic laboratory effluent. ===end of quoted portion=== Now, I did not read every single word of this article, but I did skim every page. NAg (Silver Nitrate) kept appearing. From my cursory reading, it seems that the authors are focusing completely on the silver COMPOUND Silver Nitrate-which, as we know, is NOT electrolytically isolated silver!!! Of course medical science won't discuss EIS because we can make it ourselves, and there's no profit in that. It really pays to read carefully, and read between the lines.
