Biological Synthesis of Nanosilver by Using Plants
Nanotechnology is a most promising area that is increasing day by day and play a vital role in environments, biotechnological and biomedical fields. In recent years, the development of effective green chemistry methods for synthesis of various metal nanoparticles has become a main focus of researchers. They have investigated to find out a sustainable technique for production of well-characterized nanoparticles. A variety of chemical and physical methods have been exploited in the synthesis of silver nanoparticles (AgNPs) and these procedures remain expensive, high energy consumption and involve the use of hazardous chemicals. Therefore, there is an essential need to develop environmentally benign and sustainable procedures for synthesis of metallic nanoparticles. Increasing awareness of green chemistry and biological processes has need to develop a rapid, simple, cost-effective and eco-friendly methods. One of the most considered methods is production of nanosilver using plants and plant-derived materials which is the best candidates and suitable for large-scale biosynthesis of silver nanoparticles. Eco-friendly bio-organisms in plant extracts contain proteins, which act as both capping and reducing agents forming of stable and shape-controlled AgNPs. This review describes the recent advancements in the green synthesis of silver nanoparticles by using plants.
