A method of synthesizing copper oxide nanoparticles includes preparing a liquid extract of, dissolving copper salt in the liquid extract to provide a solution with copper nanoparticles, adding a base to the solution with copper nanoparticles to form a precipitate including copper oxide nanoparticles. Copper oxide nanoparticles prepared according to the method are effective photocatalysts for degrading organic dyes and antibacterial agents and exhibit anticancer activities.

The method of producing silver nanoparticles using red sand may include the steps of adding red sand to water, mixing the red sand in the water, removing a supernatant from the red sand in water mixture after the mixture has settled, adding sodium hydroxide to the supernatant to form an alkaline solution, adding silver nitrate (AgNO) to the solution, and isolating a precipitated reaction product including the silver nanoparticles. The silver nanoparticles produced according to this method have antibacterial activity, whether used alone or in combination with standard antibiotics.

A method for synthesizing metal nanoparticles can include combining a metallic nitrate with an extract ofto form the metal nanoparticles. The method can include adding an aqueous solution of silver nitrate (AgNO) to the extract ofto form silver nanoparticles. The method can include dissolving zinc nitrate hexahydrate (Zn(NO).6HO) in an extract ofto provide a zinc nitrate extract solution, stirring the zinc nitrate extract solution, and adding an aqueous solution of sodium hydroxide (NaOH) to the zinc nitrate extract solution to form zinc oxide nanoparticles.
