Silver Nanoparticles in Therapeutics: Development of an Antimicrobial Gel Formulation for Topical Use

Silver is an effective antimicrobial agent with low toxicity, which is important especially in the treatment of burn wounds where transient bacteremia is prevalent and its fast control is essential. Drugs releasing silver in ionic forms are known to get neutralized in biological fluids and upon long-term use may cause cosmetic abnormality, e.g., argyria and delayed wound healing. Given its broad spectrum activity, efficacy and lower costs, the search for newer and superior silver based antimicrobial agents is necessary. Among the various options available, silver nanoparticles have been the focus of increasing interest and are being heralded as an excellent candidate for therapeutic purposes. This report gives…
