Abstract

Zinc oxide nanoparticles are prepared using the pulsed laser ablation approach (Nd:YAG laser at a central wavelength of 1064 nm with the pulse energy of 100 milli-joules) of the zinc metal plate immersed in a solution of sodium dodecyl sulfate at the ambient temperature. The laser fluence dependence of absorbance of the produced nanoparticles shows a single and sharp peak around 375 nm, indicating that the nanoparticles have a narrow size (45 - 60 nm) with almost spherical shape. Next, zinc oxide nanoparticles with different concentrations can hold promise in the phototoxic effect. The photocatalysis activity of the zinc oxide nanoparticles can considerably enhance the injury of a cancer cell mediated by the reactive oxygen species.
