Chemically driven micro- and nanomotors

At least since the movie "The Fantastic Voyage" in 1966, in which a submarine is shrunk down and injected into the blood stream of a human, people have been toying with the idea of sending tiny "micromachines" and "nanorobots" into our organs or individual cells to carry out delicate "repairs". This is now beginning to approach the realm of possibility. In the journal Angewandte Chemie, scientists from Stuttgart present the current state of research in the area of catalytic micro- and nanomotors
