Nanotechnology: What is It?

Nanotechnology operates at the atomic and molecular scale, offering potential for creating smaller, stronger, and more efficient products. It is already used in various everyday items. The technology is named after the nanometer, a unit of measurement for atoms and molecules. Materials at the nanoscale can exhibit different properties, such as nano silver's antibacterial qualities and carbon nanotubes' strength. Future applications could revolutionize industries, but the risks and benefits are still being evaluated.
