abstract
Nanotechnology are often described as the manipulation of materials by certain conventional and/or natural processes so as to get materials with some specifications which will be utilized in various applications including the fields of drugs, chemistry, climate, electricity, agriculture, information, communication, heavy industry, and commodity. In recent years, the event of efficient green chemistry methods for synthesis of metal nanoparticles has become a serious focus of research to having several strong benefits of biological synthesis protocols over traditionally used physical and chemical methods. They need investigated so as to seek out an eco-friendly technique for production of well-characterized nanoparticles. Among these plants seem to be the simplest candidates and that they are suitable for large-scale biosynthesis of nanoparticles. Nano-conjugates which are developed by green origin are more consistent, stable and therefore the rate of synthesis is quicker than within the case of microorganisms. Moreover, the nanoparticles are more various in shape and size as compared with those produced by other organisms. During this review, role of six different ethnomedicinally important plants: Phyllanthus amarus, Acalypha indica, Mentha spicata, Limonia acidissima, Centella asiatica, Murraya koenigii within the synthesis of metal nano-conjugates has been discussed. The prosperity of employing such plants and plant-derived compounds for the biosynthesis of nanoparticles make the researchers to find accurate yet nontoxic safe research mechanisms of metal ions uptake and thereafter their bio reduction by plants, and to know the possible mechanism of nano-conjugates synthesis.
