Researchers at North Carolina State University have developed a way to propel and rotate microbots in water.

Their microbot, which is 3 millimeters long, is essentially a diode, which they control by applying electrical fields. The development may some day allow microbots to perform remote diagnosis and drug delivery in the body, “Fantastic Voyage” style.
