Zinc Oxide (ZnO) nanoparticles are tiny particles of zinc oxide. They are usually smaller than 100 nanometers. These nanoparticles are very useful because they can kill bacteria, conduct electricity, and react with light. This makes them valuable in medicine, electronics, energy, and the environment.
Researchers are discovering new ways to use ZnO nanoparticles. Their future looks very promising.
