MICROSCOPIC submarines powered by bacteria could zip round the body
delivering drugs and zapping tumours, say researchers in Utah who are developing
a novel biomotor.
Earlier this month, the team presented their ideas at the Foresight
Conference on Molecular Nanotechnology in Bethesda, Maryland. The motor would be
ideal for navigating round the human body, says co-designer Eldrid Sequeira, a
nanotechnology researcher at Utah State University in Logan. In scenarios
reminiscent of the movie Fantastic Voyage, researchers eventually hope
to send robots round the body in the bloodstream to attack tumours with potent
drugs or scour out blocked arteries.
