Silver has been in use since time immemorial in the form of metallic silver, silver nitrate, silver sulfadiazine
for the treatment of burns, wounds and several bacterial infections. But due to the emergence of several
antibiotics the use of these silver compounds has been declined remarkably. Nanotechnology is gaining
tremendous impetus in the present century due to its capability of modulating metals into their nanosize,
which drastically changes the chemical, physical and optical properties of metals. Metallic silver in the form
of silver nanoparticles has made a remarkable comeback as a potential antimicrobial agent. 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 ranging from
silver based dressings, silver coated medicinal devices, such as nanogels, nanolotions,
