Nanomedicine is the application of nanotechnology in medicine—using materials and devices at the nanoscale (typically 1–100 nanometers) to diagnose, treat, and prevent disease. To give perspective: a nanometer is one-billionth of a meter. Many biological structures (like proteins and DNA) naturally exist at this scale, which makes nanotechnology especially powerful in medicine. https://multisciajournals.com/journals/index.php/fp
