Formation of CuO nano-flowered surfaces via submerged photo-synthesis of crystallites and their antimicrobial activity

Abstract We report the fabrication of flower-like CuO nanostructured surfaces via submerged photo-synthesis of crystallites (SPSC), which requires only UV illumination in neutral water. In this paper, we discuss the reaction mechanism of the photochemical formation of the SPSC-fabricated CuO nanostr...
