Using Nanotechnology to cure the dragon disease called cancer.
Cancer cell have a higher temperature than the body temperature. The nano bots carrying the cancer treatment drug will be temperature sensing bots, which when coming into contact with the cancer cell will open up and pour the drug directly into the cancer affected cells.
The quantity of the drug required will be less, as well as the effect will be quick and response will be quite effective.
The manufacturing of the nano bots will be easy and cheap.
