ABSTRACT

Herbs & herbal derivatives are of great research interest owing to their applications in therapeutics .Nanotechnology is making an impact in every field of life .Nanoparticles are manufactured worldwide in range quantities for use in a wide range of application. A nanoparticle has lot of scope for health care products such as burn dressing, antimicrobial applications, medical device & scaffolds. Metallic nanoparticles are being utilized in every phase of science along with engineering including medical filed and are still exploring new dimensions for their respective worth. Among several noble metal nanoparticles, silver nanoparticles have attained a special focus due to its unique physical, chemical and biological properties. Green protocol of synthesizing nanoparticles has emerged as an alternative to overcome the limitation of conventional methods .Thus to solve the objective biological approaches derived from plant sources in the form of extracts exhibits superiority over chemical or biological methods. The nanoparticles synthesis with plant based biological molecules makes it suitable .This review elaborates in detail the role of medicinally important herbs in synthesizing metal nanoparticles ,their physiological compatibility & therapeutic efficacy limitations of green synthesis of nanoparticles with their future prospects in health & diseases.

Keywords: silver nanoparticles, nanoparticles, plant extracts, biosynthesis.
