    2020-7-10 · Biosynthesis of gold nanoparticles using plant extracts is geng more popular due to the strong antibacterial action of nanoparticles and easy reduction of their salts. This simple, single step procedure appears to be suitable for large scale production as it is cost effective, rapid, environmentally benign and is safe for clinical research. Two medicinally important plants Cucurbita pepo and Malva crispa were also reported for synthesis of gold nanoparticles with potent antibacterial agent against food spoilage pathogens. Gold nanoparticles of size 20-30 nm were rapidly synthesized using aqueous leaves extract of Acalypha indica as novel source of bio-reductants. Gold nanoparticles are emerging as promising agents for cancer therapy and nano-sized gold particles have been evaluated against a variety of human cancer cells. The triangular shaped Au core-Ag shell nanoparticles were obtained by the reduction of gold ions by lemongrass extract by electrostatic complexation of Ag+ ions with negatively charged lemongrass reduced gold nanoparticles
