The metal accumulating ability of plants (hyperaccumulators) has previously been used to detoxify and environment clean up of metal contaminants from different site. However, the full potential of this process is now being explored via reuse of these hyperaccumulators in nanotechnological practices. This short review article is devoted to the ability for hyperaccumulator plants to form metallic nanoparticles by reusing the toxic metal accumulated in these plant for their positive utilization in novel nanoparticle synthesis. This approach inspires the search for new strategy of eco-benign, cost effective way on the synthesis of nanoparticle by using non renewable cost effective, eco-sustainable resources.
