Properties of Zinc Oxide Nanoparticles and Their Activity

08 05 2018Solubility of zinc oxide (1 6–5 0 mg/L) in aqueous medium is higher than that of zinc oxide nanoparticles (0 3–3 6 mg/L) in the same medium [] which is toxic to algae and crustaceans Both nano-zinc oxide and bulk zinc oxide are 40–80-fold less toxic than ZnSO 4 against V fischeri The higher antibacterial activity of ZnSO 4 is directly proportional to its solubility releasing Zn 2+ ions
