Drugs Delivered By Robots in the Blood
October 4, 2004 | Source: New Scientist
A microscopic swimming robot unveiled by Chinese scientists could eventually be used for drug delivery or to clear arteries in humans.
The 3 mm by 2 mm by 0.4 mm triangular machine is propelled using an external magnetic field that controls its microscopic fins: the speed of the craft can be changed by altering the resonant frequency of the magnetic field.
The next model of the robot will be 1 mm long.
