Anomalous antibacterial activity and dye degradation by selenium doped ZnO nanoparticles

- Band gap of ZnO NPs increased by Se doping, and exhibited defects due to oxygen vacancies.
- Enhanced photoinduced ROS generation in Se doped ZnO NPs than the pristine ZnO NPs.
- Enhanced photocatalytic dye degradation of Se doped ZnO NPs than pristine ZnO NPs.
- Reduced antibacterial activity of Se doped ZnO NPs was due to Se leaching from NPs in culture media.
