Worm glue could help repair broken bones

Bioengineers are attempting to emulate glue created by the sandcastle worm (pictured) to r...

A sea creature called the sandcastle worm could hold the secret to repairing broken bones in humans. The screws and pins favored by many surgeons today have achieved much success over the years, but they are not suitable for repairing all kinds of fractures. For more precise reconstruction of compound fractures and shattered bones, bioengineers have looked beyond metal hardware and have now duplicated a natural glue secreted by the tiny sandcastle worm. The research team hopes it will provide a better solution to fixing small bones broken in battlefield injuries, car crashes and other accidents. Read More

Microcapsules filled with carbon nanotubes could be used to repair electronic circuits (...

Dropping an electrical device such as a mobile phone or laptop can prompt a few anxious moments as you rush to see whether your beloved device has survived the fall. Now researchers at the University of Illinois at Urbana-Champaign are working to make such incidents a little less distressing - they're developing a self-healing first-aid kit for electrical systems that could stop circuits failing and lead to safer, longer lasting batteries.

Self-healing paint is just the beginning

Human skin has an amazing capacity to heal itself from scratches and cuts, so it’s not surprising that scientists are looking at transferring the self-healing properties of skin to industrial materials. Efforts to embed tiny liquid-filled capsules that rupture when a scratch occurs to spill healing agents into the damaged area of electroplated coatings have previously been hampered by the size of these capsules. But now researchers have developed a process for producing electroplated layers with nano-capsules that measure only a few hundred nanometers in diameter that could solve the problem. Read More

Self-healing car paint uses sunlight to repair scrapes

I can imagine how a lobster might scratch a car, but who would ever have thought of using one to repair a scratch in your paint? Scientists have recently developed a polyurethane coating that heals its own scratches when exposed to sunlight. Read More
