The environmentally nontoxic, ecofriendly and cost-effective method that has been developed for the synthesis of silver nanoparticles using plant extracts creates the major research interest in the field of nanotechnology. The synthesized silver nanoparticles have been characterized by the UV-VIS spectroscopy, X-ray Diffraction, Atomic force microscopy. Silver nanoparticles exhibit a broad spectrum of anti-bactericidal and anti-fungicidal activities making them extremely popular in a diverse range of consumer products including plastics, soaps, pastes, food and textiles thus increasing their market value. The presence of soluble organics in the plant extracts was mainly responsible for the silver ions reduction to Nano-sized silver particles. Thus it provides information on silver nanoparticles synthesis from various medicinal plants, various methods of characterization and its biological application.
