Nanotechnology is advancing across many aspects of science, engineering, and medicine. I am particularly impressed with what researchers at Rice University are doing. They have developed nanomotors which are incredibly small. The motors can spin at 2-3 million rotations per second. The size of the motors is mind-boggling, 50,000 of them side by side fill the width of a human hair. Even more amazing is what they can do. The day will come when you can drink a nano-cocktail. The nanomotors will seek out cells which need repairing, and when a surgeon shines a light on the motor, it can drill through the cell wall, and deliver a drug. In the case of some cancer cells, the nanomotor will drill into the cell and kill it. I know this sounds like science fiction, but researchers have actually shown the potential. 

Researchers at Rice University designed test motors to target prostate cancer cells. The nanomotors were able to break through the cell membranes and kill the cancerous cells within one to three minutes.
