Biologically inspired adhesives

We report that hydrophilic polyurethane mushroom shaped microfiber arrays possess wet self-cleaning ability using the lotus effect as biologically inspired synthetic fibrillar adhesives. Wyss institute for biologically inspired engineering at harvard sticky when wet: strong adhesive for wound healing: slug-inspired, flexible medical bio-glue sticks to wet surfaces without toxicity sciencedaily sciencedaily, 27 july 2017. Biologically inspired adhesives we are developing a novel, controllable adhesive that combines the benefits of electrostatic adhesives with gecko-like directional dry adhesives when working in combination, the two technologies create a positive feedback cycle whose adhesion, depending on the surface type, is often greater than the sum of its parts.

Edgewood chemical biological center us army research, development and engineering command ecbc-cr-097 biologically inspired polymer micro-patterned adhesives.

A new, flexible adhesive material inspired by the glue secreted by slugs adheres to biological tissues (even when wet) without causing toxicity, and can be formed into either sheets (teal blue) or custom shapes (dark blue. Synthetic adhesive interfaces and materials inspired by mussels of genus mytulis have been extensively applied, and it is expected that characterization and adaptation of several other biological adhesive strategies will follow the mytilus edulis model. We report that hydrophilic polyurethane mushroom shaped microfiber arrays possess wet self-cleaning ability using the lotus effect as biologically inspired synthetic fibrillar adhesives in comparison with a flat surface made of the same polyurethane, the fiber array exhibited almost 100% wet self-cleaning without any degradation of adhesive strength.

To address that lack, researchers at the wyss institute for biologically inspired engineering at harvard university have developed a new super-strong hydrogel adhesive inspired by the glue secreted by a common slug that is biocompatible, flexible, and can stick to dynamically moving tissues even in the presence of blood.

Biologically inspired adhesives

biologically inspired adhesives Using a wide variety of methods, we study mechanical systems and materials, which emerged during biological evolution some of these adhesive systems employ secretory substances, modulating forces in the contact area, or bear the capability of operating underwater.

Providing an illustration of the adhesive properties of the new tape, a 20 x 20 cm (787 in) square piece was able to support the weight of one team member dangling from the ceiling the researchers are also looking to nature in the form of beetle coverwings, snake skin, and anti-adhesive plants, for inspiration for other bioinspired materials.
