(A) Pacemakers work just fine. But logistically, they’re a(n) 26 : insertion is invasive, infections are common, andeven if they’re needed for only a short time, removal requires major surgery. But what if they and other medical devices likethem could be replaced with microchip-size monitors that simply dissolved when they were no longer needed?That’s the idea behind transient electronics, a new medical technology being pioneered at Tufts, Northwestern and theUniversity of Illinois at Urbana-Champaign. By making implantable devices out of bio- 27 materials—think silicone,magnesium and silk—researchers are creating the ultimate medical aid: a wi-fi-enabled gadget that can 28 medication,monitor vitals and then dissolve on demand (via a wi-fi directive) or after a set period, without any kind of surgery. “It 29an unnecessary load on the patient,” says John Rogers of the University of Illinois whose team helped develop the breakthroughtechnology.Sound too good to be true? There are some 30 . Although the science is sound—the silicon-based chips arecovered in magnesium, which naturally occurs in our bodies, and are coated with silk, which can be engineered to dissolve at acertain time—the U.S. Food and Drug Administration has yet to 31 the use of transient electronics. Moreover, thereare safety concerns, as with any implant. “Will the immune system reject it? Is it causing a reaction?” he says. “There’s alot of groundwork that still needs to 32 ,” including extensive testing in humans. Most of the researchers’ findingscome from experimenting on rats.However, the potential is 33 . “Catheters, wires and tubes can all cause infections. It's a major problem,” saysMarvin Slepian, a researcher who teaches cardiology and bio-engineering at the University of Arizona.Freed from worrying about those removal-surgery risks, doctors could use dissolvable sensors to measure temperatures,fight infections and more. “It’s a lot better for the patient,” says Slepian.For now, though, Rogers’ team is focused on perfecting the 34 technology by testing it on more animals and indifferent body parts and on finding enough low-cost and recycled manufacturing materials to make it 35 for the masses.“This is just the beginning of a new class of technology you’re going to see in humans,” he says.
