South Korea develops world’s first cancer-treating nanorobot

South Korean scientists have developed a nanorobot that both detects and treats cancer using protein sensitive bacteria.

The nanorobot is powered by a special, genetically-modified bacteria that can detect substances and proteins associated with cancer growth. Once it reaches a cancer cell, the 3-micrometer robotic device automatically sprays anticancer drugs. The robot opens the doors for a more targeted approach to fighting cancer, which is likely to have fewer side effects than conventional treatments like chemo or radiation, which attack the entire body.
