You’ve gotta love those Pomphorhynchus laevis worms. Although the parasites may feed on fish by attaching themselves to the inside of the host animal’s intestines, they’ve also provided the inspiration for a new system of keeping skin grafts secured over wound sites.  Read More

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

Mussels have an amazing ability to cling to rocks, even when buffeted by large waves and ocean debris on a daily basis. Now, scientists have created a bioadhesive gel inspired by those mussels, that could potentially be used to reinforce weakened blood vessels.  Read More

Quills may be good for more than just protecting porcupines (Photo: Shutterstock)

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

The medical tape is designed to peel off while leaving the adhesive behind

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

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

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

Streptococcus pyogenes has inspired a super-strong and selective instant adhesive (Image: ...

A strong and highly selective instant adhesive inspired by the bacterium Streptococcus pyogenes has been developed by Oxford University researchers. S. pyogenes is a common resident of human throats that is normally kept in check by the body's defenses, but when it gets out of control it can cause diseases ranging from strep throat to toxic shock syndrome or flesh-eating disease. By engineering a protein that is central to S. pyogenes' infectious arsenal, the researchers have developed a new superglue that can't be matched for sticking molecules together and not letting go.  Read More

Everyone knows geckos have extraordinary powers of adhesion, able to clamber up vertical windows with remarkable ease. With the "Geckskin", a team of scientists have replicated the effect to produce a flat, index-card sized piece of material capable of carrying a 700-pound (318-kg) load - easily enough for a flatscreen television. It can be removed with ease and leaves no unpleasant oomska. And interestingly, it doesn't work as you might think.  Read More

As is so often the case these days for those searching for a better way to stick stuff together, researchers from the Zoological Institute at the University of Kiel in Germany have turned to the biology of gravity-defying ceiling walkers, such as geckos and insects. These creatures served as inspiration for a new dry adhesive tape that not only boasts impressive bonding strength, but can also be attached and detached thousands of times without losing its adhesive properties.  Read More
