Medical nanotechnology can be defined as a medical branch or application of nanotechnology using different approaches, such as nanoelectronic biosensors, nanomaterials, and molecular manufacturing. Medical nanotechnology provides cheaper and high-quality healthcare, medical equipment, facilities, and treatment strategies. Due to medical nanotechnology, medical tools become cheaper and more effective, research and diagnosis are much more efficient, enabling rapid response to new diseases, including engineered diseases. Small, cheap, numerous sensors, computers, and other implantable devices enable a constant health monitoring and semi-automated treatment. Nanomedicine is non-invasive and generally puts a minimal amount of strain on the patient. This solution alone, creates one of the greatest advantages of this type of treatment and also gives several new kinds of treatment. As the practice of nanomedicine becomes cheaper and less uncertain, it can be available to more people.
