particular part of the human body, through the blood
(Drugs delivered by robots in the blood_)
A microscopic swimming robot unveiled by Chinese
scientists could eventually be used for drug delivery
or to clear arteries in humans, say researchers.
The 3 millimetre-long triangular machine was
constructed by Tao Mei of the Chinese Academy of
Sciences, Beijing, and colleagues from the University
of Science and Technology of China.
The craft is propelled using an external magnetic
field which controls its microscopic fins. The fins
are made from an alloy that contracts in response to
application of the field. Applying the field quickly
makes the tiny submersible paddle forwards and
gradually switching the field off slowly moves the
fins back to their original position.
