Getting a grip on ivy's adhesive properties

Anyone who has tried to clear ivy from the side of their house will know the climber is almost impossible to unstick. A team at Ohio State University has studied the tiny particles giving ivy its vise-like grip, with a view to creating better medical and industrial adhesives, and even stronger armor.Read More

Reversible adhesive can be turned on and off as required

Reversible, temporary adhesives may not sound all that exciting to some, but to a manufacturer that needs to rapidly move small, difficult-to-handle components or a robot-builder creating a machine that can climb any surface, such products are the thing of dreams. Now researchers at the Max Planck Institute have created a reversible adhesive from the metal gallium that displays reversible glue-like properties that could have applications in everything from industrial electronics pick-and-place processes, short-term silicon wafer bonding, to switchable adhesive feet for climbing robots.Read More

Sandcastle worms inspire strong, fast-acting underwater adhesive

Science has turned its torch to many corners of the animal kingdom in the pursuit of advanced adhesives. Immoveable mussels, grippy geckos and stubborn shellfish have helped nudged these efforts along in the past, and now another critter has emerged with a few sticky secrets of its own. Researchers have replicated the adhesive secreted by sandcastle worms to form a new kind of underwater glue, a substance they say could find use in a number of applications including tissue repair and dentistry.

Sorry Spider-Man, but geckos are the largest wall crawlers

Having faced off the Green Goblin and Mysterio, Spider-Man has been defeated by his greatest enemy; maths. According to a team of scientists from Cambridge University, for the webslinger to stick to a wall, he'd need hands and feet equal to 40 percent of his entire body surface area. Though this may dismay web head's fans, it may shed insights into how to improve gecko-like adhesives.Read More

Gecko-inspired adhesive tape finally scales to market

The natural stickiness of gecko's feet has inspired decades-long research efforts to develop advanced adhesives. Now a company spun out of a university research group called nanoGriptech has taken the science out of the lab and into the market, through a number of newly available products promised to deliver enhanced grip and reusability.Read More

"Voltaglue" sticks in the wet and hardens when voltage is applied

A glue that performs at a high-level in wet environments could bring about all sorts of possibilities in areas like surgical care and ship maintenance. A somewhat common approach to this problem has been trying to replicate the freakish ability of mussels to bind themselves to boats and jetties, but a team from Singapore's Nanyang Technological University is coming at it from a slightly different angle by developing a glue that hardens when an electrical charge is applied.Read More

Mussel-inspired surgical glue shuts down bleeding wounds in 60 seconds

The ability of mussels to stubbornly bind themselves to underwater surfaces has intrigued scientists for years. If this ability could be recreated in the lab, it could lead to new adhesives for all kinds of applications. A team of Korean scientists has now developed a surgical glue inspired by these natural wonders that's claimed to be cheaper, more reliable and incur less scarring than existing solutions.Read More

Clingfish could inspire safer surgeries and better whale-tracking

Mussels have an incredible ability to cling to wet surfaces. It's an ability that scientists are trying to replicate for use in man-made adhesives. That adhesion can't be turned on and off as needed, however, limiting its potential applications. That's where the Northern clingfish comes in. It can suck onto rough, slimy surfaces, supporting up to 150 times its own body weight when lifted. That said, it can also just let go and swim away whenever it wants. Scientists from the University of Washington now understand how it's able to do so, and are looking at applying the principle to fields such as surgery and whale-tracking.
