Nanomedicine is the application of technology to do everything from drug delivery to the repairing of cells. It is the application of tiny machines to the treatment and prevention of disease. Nanorobots are advancements in Nanomedicine as miniature surgeons. These machines help repair damaged cells they replicate themselves, correct genetic deficiencies by replacing or altering DNA molecules. For example artificial antibodies, antiviral, Nanorobots, artificial white and red Blood cells. These Nanomachines could affect the behaviour of individual cells. Hormones or Dispense drugs as needed in people with deficiency states or chronic imbalance can be solved using implanted Nanotechnology devices.
