Extracellular synthesis of silver nanoparticles by Aspergillus niger

Biological synthesis of silver nanoparticles (Agnps) is a rapidly developing area in the field of nanobiotechnology. Wide research is going on ecofriendly synthesis and antimicrobial mechanisms of the Agnps. In this book the possible mechanisms for the synthesis of silver nanoparticles by the microbes and the mechanistic modes of antimicrobial activity of silver nanoparticles were discussed and the research work involved in the synthesis of Agnps using fungi Aspergillus niger was included. Finally the book ends by giving information on biological synthesis of silver nanoparticles and the various methods involved in characterization of nanoparticles and their antimicrobial efficacy against pathogenic bacteria, fungi and virus that causes diseases in plants and human beings.
