Description
Abstract We investigated whether Aluminum (Al) doping tunes band gap energy level as
well as selective cytotoxicity of ZnO nanoparticles in human breast cancer cells (MCF-7).
Pure and Al-doped ZnO nanoparticles were prepared by a simple sol-gel method.
Characterization study confirmed the formation of single phase of Al x Zn 1-x O nanocrystals
with the size range of 33–55 nm. Al-doping increased the band gap energy of ZnO
nanoparticles (from 3.51 eV for pure to 3.87 eV for Al-doped ZnO). Al-doping also …
