要約(日本語): A magnetic micromachine capable of moving in a liver was fabricated. It consisted of a stainless steel tip, a permanent magnet, and a spiral shape made with a tungsten wire. The magnet was magnetized in the direction of its diameter. The diameter of the machine was 0.9 mm, small enough for it to be inserted by means of a medical injector. When a rotational magnetic field was applied, the machine rotated and moved in a liver. The micromachine was able to move a distance of 45 mm in bovine liver. It thus has great potential for medical applications.
