ABSTRACT
Nanotechnology is a rapidly growing field with many innovations and numerous new characteristics. Nanotechnology, as an interdisciplinary approach, has successfully come up with trailblazing ideas in various fields of science and is also expected to play a vital role in revolutionizing the biomedical fields. Biogenic synthesis of nanoparticles is an environment-friendly and sustainable approach. It is useful in the safe and effective production of nanoparticles. Plants have numerous organically dynamic parts which possess a reducing ability in creating metallic nanoparticles with effective remedial potential. Plant-based products such as vitamins, tannins and aroma are responsible for most of the reduction of metals salts to metal nanoparticles. Phytoremediation is the eco-friendly and natural process in which certain plants and related microbes lower the toxicity in the soil. The major requirement for phytoremediation is the selection of suitable plants. In phytoremediation, the plant extracts toxic elements present in the soil and converts them into less toxic forms without contaminating the food chain. Medicinal and aromatic plants are natural raw material produced as secondary metabolite which shows biological activity and has many limitations but can be overcome with the use of nanoparticles. If used with nanoparticles, they act as elicitors. Aromatic plants possess antimicrobial and antioxidant activity and have been useful for the phytoremediation of heavy metals. There is a lot of examination on the synthesis of nanoparticles involving medicinal and aromatic plants as reducing agents alongside their organic activities enhance the phytoremediation potential of plants.
