Nanotoxicology is the study of how very tiny particles called nanoparticles can affect our health and the environment. Since these particles are so small, they can enter our bodies through the air we breathe, the food we eat, or through our skin. While nanotechnology brings many benefits, like better medicine and stronger materials, scientists also need to make sure it's safe. Nanotoxicology helps us understand if these tiny particles can be harmful and how to prevent any risks. Researchers study how nanoparticles interact with cells and organs, and how they move through the body. This helps create rules and safety standards to protect people and the planet. At major science events like the NanoTechnology World Conference, experts in nanotoxicology discuss the latest research on keeping nanotechnology safe for everyone.
