If scientists in the College of Illinois get their say, bandages are going to get a great deal cooler.
After 1 week, new bloodstream ships mirror the bandage's own pattern.
(Credit: Micro and Nanotechnology Lab)An engineering team has produced a bandage that in only 1 week not just encourages new circulation system growth but helps guide that growth too.
"A chance to pattern functional bloodstream ships only at that scale in living tissue is not shown before," co-principal investigator and electrical and computing engineering professor Rashid Bashir states inside a school news release.
They, whose findings will sophistication the coverage of the The month of january 2012 problem from the journal Advanced Materials, calls the bandage a "microvascular stamp." Unlike similar bandages designed to help spur circulation system growth, the stamp consists of living cells that encourage broken tissue to develop based on the stamp's pattern.
At nearly a centimeter across, the stamp consists of porous material that allows small molecules to sneak through additionally towards the bigger growth factors. They examined it on the chicken embryo once they took it off in the surface not much later, a network of recent bloodstream ships made an appearance within the pattern from the stamp's channels.
Future programs could include not just healing wounds, but additionally redirecting bloodstream ships to develop around blocked arterial blood vessels, as well as enhancing the delivery of cancer drugs by repairing bloodstream ships that feed cancerous cells.
