New superglue fixes holes in the heart

A hole in the heart is never a good thing, so when an infant is born with such a defect, doctors have to act quickly to fix it. Unfortunately, both sutures and staples can damage the heart tissue, plus it takes too long to apply sutures. Existing surgical adhesives have their own drawbacks in that they can be toxic, and they typically become unstuck in wet, dynamic environments such as the heart. As a result, infants often require subsequent operations to "replug" the hole. Now, however, scientists have developed a sort of superglue for the heart, that quickly and securely bonds patches to holes. Read More

FiberFix aims to make duct tape look pathetic

People may make jokes about how duct tape can be used to fix just about anything, but a new product is claimed to be 100 times stronger than our matte-silver friend. It's called FiberFix, and it's a tape impregnated with a resin that reportedly "hardens like steel."Read More

Prefab houses could soon be taped together

Prefabricated houses are made up of separate pre-assembled modules that are joined to one another on-site – those modules, in turn, are made up of various wooden components that are typically nailed (or sometimes stapled) together in a factory. The wood used in the frames of the modules must be reasonably thick, in order not to split when the nails are driven in. This places some limitations on design possibilities. Now, however, German scientists have developed an alternative to those nails: electrically-activated adhesive tape. Read More

Study of remoras may lead to new adhesives

If you’ve seen even a few minutes of any documentary on sharks, then chances are you’ve seen a remora. They’re the smaller fish that hitch rides on sharks by sucking onto them. Not only are the remoras able to achieve a seal against their hosts’ rough, sandpaper-like skin, but they also don’t appear to harm that skin in the process. Researchers from the Georgia Tech Research Institute are now studying how the remoras manage this, in hopes of applying their findings to the development of next-generation adhesives.Read More

Porcupine quills inspire new medical innovations

If you’ve known a dog that’s been quilled by a porcupine, then you’ll know that while those quills go in all-too-easily, it’s very difficult to pull them out. As part of a new research project, however, a team of scientists are looking at replicating those very characteristics in things like hypodermic needles and surgical adhesives. It turns out that what’s a bane to overly-inquisitive dogs may be a boon to medical technology.Read More

MIT researchers develop painless medical tape for newborns

Pulling off a finger plaster is one of life’s little trials that can reveal a lot about a person. Do it fast or do it slow, it still hurts like heck and there’s no pretending that it didn't. For an adult, it’s an instant of pain, but for a newborn it can mean injury or even permanent scarring. In order to prevent this, a team of researchers are developing a new medical tape that can be pulled off safely without tearing delicate infant skin.Read More

New tech converts regular paper into powerful medical diagnostic tool

A group of researchers at the University of Washington has found a way to isolate and identify medically interesting molecules using little more than scraps of office paper, a Ziplock bag and a cheap diluted solvent. If properly developed, the system – which requires minimal costs and know-how to build and operate – could be made to administer a wide range of medical tests nearly free of charge.Read More

Bringing Teflon and silicone together shows promise for medical applications

Polytetrafluoroethylene (PTFE) is best known by the DuPont brand name Teflon. Whatever it is called, PTFE is the third slipperiest solid known – the poster child for non-stick, non-reactive, non-friction, non-conducting, high-temperature, and generally high-performing polymers. Silicone also has a nearly non-bondable surface – if you try to paint a silicone sealant, it simply pops off as the paint dries. In particular, creating a strong bond between PTFE and silicone has never been accomplished, even in the chemical laboratory. Until now.Read More
