Walking DNA Scientists have created a microscopic walking robot using only the building blocks of life. The robot’s DNA legs move along a DNA footpath, taking a nanostroll in a bath of a liquid called a "nondenaturing buffer", which stops the DNA from falling apart.

Scientists have created a miniature medical computer out of DNA that can detect cancer genes in a test tube and respond by releasing a drug.
