When people get infection in the blood, they are in very bad risk to die, if antibiotics don't take effect to that organism. The problem with amoebas and worms is that that protozoan is that they are so huge in front of our leukocytes. That's why they will eat our leukocytes, and only thing, what is left for destroying those protozoans from our blood are huge doses of antibiotics. The mission for those antibiotics is to kill those animals from our blood. But the problem is that those antibiotics will kill also our normal cells and that's why they are dangerous to use. The solution of that problem might be found from nanotechnology.

Nano-machines can destroy those very dangerous things with making holes in their body, and by forcing them to die. Those new type of intelligent nano-machines can communicate with, microchips what are implanted to the human body. But nanotechnology can do much more with human health. In some accidents and poisoning, cases will oxygen level in the human body can decrease in extremely low level, and some people see nanotechnology as a solution for that problem. In this scenario in the human body will inject tiny balls, what is filled with oxygen. Those little balls will be carried to cells, and there they will release oxygen. 

Nano-robots might use in accidental cases to carry cells to the target. Those cells might be grown outside of the human body, and small robots will carry them to the right place of victims body. That will help fix those injuries very fast. Those cells will inject to person's body, and there those little robots will begin to carry them to bones and muscles what are damaged in that accident. In the wildest dreams, those tiny machines give the person a super-immune-system. In those visions, that kind of machines can even replace human leukocytes and in some scenarios, those machines will defend us from an attack of bears and snakes. If a bear or some other species attack a human, those nano-machines will attack against that animal and make it body liquid.

But there are more impressive visions about what technology can be made for human cells in the case when there is a problem with oxygen level. The vision is to use genetic manipulation to increase human performance. It would be done with specially modified viruses, to transfer the genetics what makes photosynthesis possible from vegetables to human cells. After that, there could be possible that human skin will start to use photosynthesis in the human body. That, of course, will rise oxygen level in that person's skin. That biological advantage can increase human performance very much.
