Silver nanoparticles because of their unique properties have drawn attention of researchers worldwide towards various applications in different fields.The surface plasmon resonance exhibited by the silver nanoparticles enables them to be utilized as anti microbial coating agents. Textiles, surgical instruments, utensils, packaging materials and paints can be rendered anti microbial and it can be made impervious to microbial attack. This book will explain about rapid synthesis of silver nanoparticles and their properties which are effective against common microbes which are responsible for infection.
