Scientists Have Created Self-Healing Fabrics that Also Protect from Harmful Chemicals

Scientists Have Created Self-Healing Fabrics that Also Protect from Harmful Chemicals | Biomimicry | Scoop.it

2Protective clothing is critical to the health and safety of workers who handle hazardous chemicals. A new fabric coating promises to not only neutralize toxins, but also to heal tears and holes on its own while the clothes go through the laundry. The coating, developed by a team of researchers from Penn State and Drexel University, is derived from proteins that make up the rings of teeth on squid suckers."

Researchers Uncover the Secret Behind Ivy’s Natural Adhesive

Researchers Uncover the Secret Behind Ivy’s Natural Adhesive | Biomimicry | Scoop.it

"Charles Darwin was the first to observe that Ivy exudes a liquid adhesive that helps it to cling to surfaces. Now researchers at Ohio State University have identified the protein that allows Ivy to stick. Nanospherical arabinogalactan proteins (AGPs) allow Ivy’s adhesive to enter nanoscale openings rather than just coating surfaces. Curing takes place due to calcium-driven electrostatic interactions among carboxyl groups of the AGPs and pectic acids. As water evaporates from the adhesive, chemical bonds are formed between adhesive and substrate. The researchers say that their discovery opens up the possibility of applying its findings to the development of adhesives for a wide range of applications ranging from medical adhesives to coatings and even cosmetics."

Getting a Grip on Mussel Adhesion

Getting a Grip on Mussel Adhesion | Biomimicry | Scoop.it
The Asian green mussel (Perna viridis) anchors itself underwater by timed secretion of adhesive proteins from threadlike foot extensions, a team of researchers in Singapore finds1.

Lab experiments and computer simulations reveal that an especially long sticky protein acts as a primer — first catching the surface and repelling water molecules to make way for two proteins that form the final adhesive pad.

The discovery could lead to new submersible glues or improved paints to prevent biofouling on ship hulls and drilling platforms.

North Face's New Jacket is Made From Synthetic Spider’s Silk

North Face's New Jacket is Made From Synthetic Spider’s Silk | Biomimicry | Scoop.it

"Spider's silk is as strong as steel, lighter than carbon fibre and tougher than Kevlar.  Several research groups are hoping harness these remarkable properties by creating synthetic versions of the material.

Now, North Face has partnered with one of these teams to create a jacket made from a fiber named 'Qmonos' – the Japanese word for spider."
