An advance in micromotor technology is opening the door to broad new medical and industrial uses for these tiny devices, scientists said the national American Chemical Society meeting this week.

Akin to the invention of cars that fuel themselves from the pavement or air, rather than gasoline or batteries,

Joseph Wang, D.Sc., who leads research on the motors, said that efforts to build minute, self-powered robot devices have evoked memories of the 1966 science fiction film Fantastic Voyage. It featured a miniaturized submarine, which doctors injected into a patient. It then navigated through blood vessels to remove a blood clot in the brain.

Scientists at The Methodist Hospital Research Institute have found a possible way to fool the immune system to prevent it from recognizing and destroying nanoparticles before they deliver their drug payloads.

“Our goal was to make a particle that is camouflaged within our bodies and escapes the surveillance of the immune system to reach its target undiscovered,” said Department of Medicine Co-Chair Ennio Tasciotti, Ph.D., the study’s principal investigator.
