Nanotechnology involves working with materials at the nanoscale, between 1-100 nanometers. At this scale, materials exhibit new properties and functions. Nanotechnology is being applied in various fields including information technology, energy, medicine, and consumer goods. It allows for smaller, more powerful electronics, more efficient energy production like solar cells, targeted drug delivery, and improved materials. While nanotechnology provides benefits, potential risks also exist regarding its effects on human health, the environment, and society which require further study.
