Abstract

In the last decade, synthesis of nanoparticles has been the subject of a lot of studies due to its commercial importance and applications. Their interesting characteristics and wide application has led to numerous methods being developed for synthesis of nanoparticles of various shape and size. Typically, the methods employed for the synthesis of nanoparticle includes physical, mechanical and chemical method, but these methods are very expensive and which involve hazardous chemicals. Therefore, there is emergent need to develop environmentally benign and sustainable methods for nanoparticle synthesis that do not use toxic chemicals in the protocols. Green chemistry process that led to environmental friendly and safe synthesis process as compared to other methods. Using biological sources such as fungi, bacteria, actinomycetes, algae and plant materials, viruses etc can catalyze specific reactions to modern and realistic biosynthesis strategy that can be alternate to other physical, chemical methods, ultraviolet irradiation, lithography, laser ablation, ultrasonic fields, and photochemical reduction techniques. The general outline of this present work includes information of the different microbial sources, importance of physicochemical characteristics, and the applications of metal nanoparticles. The advances trace the route from the general, molecular, catalytic, and functional information obtained under close to optimal conditions for biological production through action of enzymatic properties and the commercial applications to the “current perspectives” including the precise and specific analysis of nanoparticles, biological systems that may support and revolutionize the art of synthesis of nanoparticles, and potential antimicrobial uses and to understand the biochemical and molecular mechanisms of nanoparticles formation are also included.
