The silver nitrate drops are still used to prevent contracting gonorrhea from mother to new born.
This proves antibacterial effects of silver ion is higher than most of the bactericidal metals followed by mercury, lead and copper. The oligodynamic action of silver ions is observed at. Killing of antibiotic resistant microbe/ microorganism by the low concentration of silver/ metal at low concentration is known as “oligodynamic effect”. In India ,Maharaja of Jaipur used fashionable silver urns to transport sacred Ganga river water. Earlier examples are ancient dynasties of the Egypt and Middle East. Silver has an ancient history of purification of potable water. Silver wire suture was used in hernia operation and silver foil for preventing post operation infection. Silver has been used in the treatment of human diseases such as neonatal eye disease, cholera and wound infection. Silver is also used in electroplating, dental amalgam, batteries, photography etc. Pure silver and its alloys are used in coinage, silver ware, jewellery widely. INTRODUCTION: Silver is extracted from argentitle (Ag2S) and horn silve AgCl).
Exposure of nanosilver products is far less than to conventional silver products and synthetic chemical antimicrobials Keywords: Nano silver particles, microorganism, biocidal, algaecides, disinfectants, EPA Nanosilver has been safely used in direct aquatic applications and dermal wound care since decades. Nanosilver products safety data available in EPA’s formal incident reporting database (EPA OPP IDS) indicates that nanosilver products are safe. Recent applications of silver nano particles in medical devices, silver dressings, silver coated textile fabrics, silver-nano particle-embedded antimicrobial paints, antimicrobial surface functionalization of plastic catheters, antimicrobial gel formulation for topical use, antimicrobial packing paper for food preservation, silver-impregnated fabrics for clinical clothing, nano silver children products and products for pets are described. Nanosilver EPA approved products such as silver biocidal additives, silver-impregnated water filters and silver algaecides and disinfectants historic development is described.
