While the scientists that developed these newfangled ingestible microgrippers call them minimally invasive, we’re not so sure that swallowing minuscule devices that can cut and grab tissue when chemically activated fits our definition of keyhole surgery. Nevertheless, tiny “handlike grippers” are currently being shown off to highly intelligent professionals in the medical realm, and if proven feasible, they could one day be used to perform biopsies from within. More specifically, the devices could reportedly “react to the biochemicals released by infected tissue by closing around the tissue, so that pieces can be removed for analysis.” Yeah, we reckon this is a bit less painful than actually going under the knife, but the mere thought of having blade-wielding microorganisms floating around our innards spooks us just a wee bit. Go on, fling your “pansies!” this way — we can take it.

Usually when we talk about robot grip strength, it’s in the context of being slowly crushed to death during a violent robot uprising, but it appears we now have to fear our bodies being stolen away cell-by-cell as well. That’s the terrifying reality being brought to life at the University of Toronto, where researcher Yu Sun and his team have developed semi-autonomous microscopic robo-tweezers that can sense touch and grip strength acutely enough to pick up and move individual heart cells during tests without damaging them. The tiny rig is just .1 inches long, and the grippers on the ends are fine enough to pick up cell just 10 micrometers wide. So far they’ve just been arranging cells during testing, but Yu says eventually they can be used to assemble silicon parts on circuit boards, or even engineer tissue. No word on when these might hit production, but when they do Yu says he expects them to cost just $10 each. At least the revolution will be inexpensive, we guess.
