Metallic silver in the form of silver nanoparticles has made a remarkable comeback as a potent antimicrobial agent. The most prominent nanoparticles for medical uses are nanosilver particles which are known for their high antimicrobial activity. Silver ion has been known as a metal ion that exhibit antimildew, antimicrobial and anti fungal properties for a long time. In particular, it is widely used as silver nitrate aqueous solution which has disinfecting and sterilizing actions. The use of silver nanoparticles is also important, as several pathogenic bacteria have developed resistance against various antibiotics. Hence, silver nanoparticles have emerged up with diverse medical applications. This book, therefore, provides information regarding the various synthesis and application methods of nanosilver. This book is useful to professionals and students from the field of Textiles, Medical and Garment industries.
