Octo Mag

Electrical engineers in Zurich, Switzerland have developed a magnetically guided “microbot” that can perform precise surgical or drug delivery procedures in the eye.  “OctoMag,” as the system is called, relies on several electro-magnets which generate force fields to move the microbot in three dimensions.  The bot itself is 285 millionths of a meter and is needle injected into the eye where it can eliminate a blood clot—as animal tests have shown.  See the video.  MORE
