DNA Damage Upon UV Illumination in the Presence of Inorganic UV-Shielding Materials

Abstract:

White nanoparticles of calcia-doped ceria were prepared from the precipitate by reacting CeCl3-CaCl2 mixed solution with NaOH solution at pH 12 and the oxidation with hydrogen peroxide solution at 40oC, followed by the calcination at 700oC for 1 h. Ceria particles generated far less singlet oxygen and caused far less damage to the DNA plasmids upon UV illumination than either the titania or the zinc oxide reference pigments.
