HOLY FREAKING HELL. Some crazy MFers have decided to make a little magnet-controlled gripper guy that closes its FIST of DEATH on cells or other things when the temp or other chemical conditions change. Be sure to watch the video on the above linked site where the gripper MERCILESSLY RIPS a chunk of some suspiciously-BLOODY-looking substance off. GRUESOME.

especially the figure on how the "hand" was made.
This is a clever way to use a swelling gel. The article does not say what the "polymeric trigger" is. I suspect it is poly(isopropyl acrylamide), but why doesn't the article say?
This guys is clearly an engineer and not a chemist.
I would like a little less focus on the cleverness of the application and more on how the device works.
