Plant extract mediated synthesis of silver and gold nanoparticles and its antibacterial activity against clinically isolated pathogens

► The paper emphasizes the heat stable bioreductant present in the plant extracts for the synthesis of nanoparticles. ► The research highlights in the paper is included elaborated procedures and review in this aspect. ► The nanobiotechnological and medical application work in the plant, Mentha piperita at the first time. ► This is a one among few plant has role to synthesis of both silver and gold nanoparticles. ► To the best of our knowledge, this may be the first report on sterilized plant extract has been used in this direction and antibacterial property also been observed from the synthesized nanoparticles against clinical pathogens.
