Japanese researchers create medical microbot

from the in-a-spin dept.
The New Scientist Magazine reports that a team of micromachine experts at Tohoku University in Japan have developed a millimeter scale medical robot that could swim along veins, ferrying drugs to infected tissues, or even burrow into tumours to kill them off with a hot lance. The devices are actually tiny spinning screws based on cylindrical magnets. Measuring eight millimetres long and less than a millimetre in diameter (about the size of a rice grain), each magnet is made of a neodymium-iron-boron alloy. When an external magnetic field is applied, the screws literally drill their way through fluids or, in one test case, two centimeters of solid flesh (beef steak).
