Nanomedicine is a branch of medicine that aims to use nanotechnology?that is, the manipulation and fabrication of materials and devices with a size of 1 to 100 nanometres (nm; 1 nm = 0.0000001 cm)?to prevent disease and to image, diagnose, treat, repair, and regenerate biological systems. Despite the fact that Nanomedicine is still in its infancy, a variety of nanomedical applications have been created. The development of biosensors to aid in diagnostics and vehicles to give vaccines, medicines, and genetic therapy, as well as the development of nanocapsules to aid in cancer treatment, has been the focus of research thus far.
