Once programmed and put into the body, the nano robots can help control all operations, the change in the division, can intervene if there are warning signs of unusual illness us. We will actively attack the pathogen, isolation of pathogenic cells accurately, while ensuring the safety of other healthy cells from infection. In particular, for cancer, nano robots will kill all the cancer cells without affecting other cells as a current conventional chemotherapy. In addition, nanotechnology will also bring many promising better health care for humans. Professor Robert Freitas, a leading expert in nano robot technology has successfully fabricated a tiny robot capable of accommodating up to 9 billion molecules of oxygen and CO2, about 200 times the transmission capacity of oxygen and CO2 of red blood cells in the blood. Therefore, people can use it in anaerobic environments and submerged for about 15 minutes. Furthermore, nano robot programming could also help boost eyesight, hearing, memory, ...
