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.

One Day We'll Fix Everything With Glues Copied From Mussels, Oysters, And Barnacles

One Day We'll Fix Everything With Glues Copied From Mussels, Oysters, And Barnacles | Biomimicry | Scoop.it

"A researcher has figured out a way to take the power of natural glues and make non-toxic and incredibly strong synthetic adhesives. It could help do everything from securing broken bones to manufacturing cars."

Nature’s Strongest Super-Glue Comes Unstuck

Nature’s Strongest Super-Glue Comes Unstuck | Biomimicry | Scoop.it

"An international team of scientists led by Newcastle University, UK, and funded by the US Office of Naval Research, have shown for the first time that barnacle larvae release an oily droplet to clear the water from surfaces before sticking down using a phosphoprotein adhesive."

Programmable Gue Made of DNA Directs Tiny Gel Bricks to Self-assemble

Programmable Gue Made of DNA Directs Tiny Gel Bricks to Self-assemble | Biomimicry | Scoop.it

"Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have found a way to self-assemble complex structures out of bricks smaller than a grain of salt. The self-assembly method could help solve one of the major challenges in tissue engineering: regrowing human tissue by injecting tiny components into the body that then self-assemble into larger, intricately structured, biocompatible scaffolds at an injury site. The key to self-assembly was developing the world’s first “programmable glue.” The glue is made of DNA, and it directs specific bricks of a water-filled gel to stick only to each other."

Sam McCormick's curator insight, March 20, 2013 8:55 AM

This article provides a number of examples of biomimetics informing medical technology. While not all are directly related to robotics, some do offer exciting possibilities including adhesive that sticks in wet conditions (for post implantation modifications or adhesion to internal anatomical structures) and a biodegradable chip that dissolves safely into the blood stream.

Mussel Goo Inspires Blood Vessel Glue

Mussel Goo Inspires Blood Vessel Glue | Biomimicry | Scoop.it
A University of British Columbia researcher has helped create a gel - based on the mussel's knack for clinging to rocks, piers and boat hulls - that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.
