Researchers at MIT and Massachusetts General Hospital have devised a new drug delivery system that contains micro-needles.  The device could deliver insulin, antibodies and other therapies.  The capsule is coated with tiny needles and delivers the medication painlessly in the gastrointestinal tract, as there are no pain sensors in the intestines.  Presently, this technology has been used successfully in administering insulin in pigs.  Researchers are looking into making biodegradable needles and adding sugar that would break off, embed in the gastrointestinal tract, and continue to deliver the medication as the sugar molecule disintegrates. Further research is required to modify the capsule so that the movement of the gastrointestinal tract would squeeze the medication out of the capsule.
