Abstract
A method of using ZnO particles for the treatment of colon cancer and a method of using the particles for reducing the concentration of an organic contaminant in an aqueous solution is described. The ZnO particles are substantially spherical and may have nanopetals that provide a nanoflower morphology. The synthesis and characterization of the ZnO particles is also discussed.
