World’s First Ciliary Microrobots Deliver Drugs Faster

Sep-19-16 A new fast-moving, microrobot inspired by the paramecium could deliver treatment directly to the affected region eight times faster than current designs.

Developed by a team from DGIST, the microrobot’s propulsion is based on the paramecium, which has evolved with an array of hair-like cilias to travel the liquid environment of the body. With this in mind, the bot was created using 3D laser lithography to build the ciliated base structure. A layer of titanium and nickel was then placed over the cilia, to provide the magnetic control and biological compatibility. An electromagnetic coil system triggers the cilia to move back and forth, propelling the tiny bot through the liquid, where it can be deftly maneuvered through veins while also carrying a heavier payload than current iterations.
