Tea Plant Leaves for Green Synthesis of Metallic Nanoparticles

“…The Ag NPs were found to be of spherical shape with a particle size between 10 and 20 nm. [ 64 ] The colloidal systems of AG NPs (stabilized by bio‐molecules present in the C. sinensis aqueous solution) have been reported previously. [ 65 ] These play an important role in the formation/ luminescence response of the noble metallic nanostructures.…”

“…mixed 20 ml of plant extract with 200 ml, 0.04 mM AgNO 3 solution and ultrasonicated the reaction mixture for two days. The nanoparticles were then washed with alcohol to remove unreacted ingredients from the Ag NPs produced [53] . Mani and his colleagues took 10 ml of plant extract and mixed it with a 10 ml AgNO 3 solution.…”

Antibacterial and plant growth-promoting properties of novel Fe3O4/Cu/CuO magnetic nanoparticles

“…Bacteria have a lower need for Cu than plants, therefore Cu ions at a particular concentration can boost plant development and cause harm to bacteria. 8,10,39,41 Because the bacterial surface has a high concentration of phenolic hydroxyl and carboxyl groups, the surface is retained in an acidic environment, where FC performs the Fenton reaction, producing additional ROS to boost antibacterial activity.…”

“…On the other hand, being a heavy metal, copper may be harmful to plants, bacteria and viruses to a certain extent. 3,4,[6][7][8] Cu 2+ is the primary component of commercial inorganic antibacterial agents such as Bordeaux mixture, green depot, and double spirit, which are extensively used in agriculture, forestry, and animal husbandry as a disposable dosage for disease prevention and control. 2,3,5 Cu 2+ ions can adsorb on the surface of bacteria, destroying the potential difference between the surface membrane and the bacterial cell walls.…”
