As you know, the usual way of treating drugs is to bring the effective substance into the body, and in addition to the diseased cells, it spreads to healthy cells and tissues. This causes very high levels of drug intake and, more importantly, damages the healthy tissues of the body. Using nano scale technology, researchers are developing nano-sized capsules that, in addition to their unmatched size, have the ability to diagnose diseased tissues, they are precisely on these tissues and give them the amount of drug they need. This phenomenon is called medication. Nanotechnology will also pave the way for building body-compatible organics and will cure many non-curable diseases. In the case of cancer treatment, researchers are also developing nanoparticles that, once they enter the body, detect and destroy cancerous tissues, even if they are as numerous as cells. This will cause cancerous tissues to be detected and destroyed in the early days of the formation. Generally, in the coming years, prevention, diagnosis and treatment of diseases will be very different from what is nowadays called medicine.
