Controlling cell adhesion on polyurethanes
Soft Matter, 2008Cell attractive or non-attractive surface properties of polyurethane devices can be controlled by treating them with zirconium tetra(tert-butoxide). This gives reactive interfacial zirconium complex species that can be used subsequently to bond cell attractive peptides such as arg-gly-asp (RGD) or cell non-attractive organics such as polyethylene ...

Controlling Polymer Adhesion with “Pancakes”
Langmuir, 2005Topographical patterns are used to selectively tune the adhesion of polymers. Although nature has provided guidance, relatively little is known of how topographic patterns can be intelligently used not only to enhance adhesion but, more importantly, to tune adhesion.

Surface Adaptable and Adhesion Controllable Dry Adhesive with Shape Memory Polymer
Macromolecular Rapid Communications, 2022AbstractGecko feet consist of numerous micro/nano hierarchical hairs and exhibit a high adhesion onto various surfaces by van der Waals forces. The gecko, despite its mighty adhesion, can travel efficiently with a rapid adhesion switching due to the end of the hairs on the gecko feet are slanted in one direction.

Skin Adhesives with Controlled Adhesion by Polymer Chain Mobility
ACS Applied Materials & Interfaces, 2018Wearable devices have attracted a lot of attention because of their importance in the biomedical and electronic fields. However, as one of the important fixing materials, skin adhesives with controlled adhesion are often ignored. Although remarkable progress has been achieved in revealing the natural adhesion mechanism and biomimetic materials to ...

Controlling Peritoneal Adhesions
Veterinary Surgery, 1982The normal peritoneum heals in five to seven days regardless of the size of the defect, because it does not heal by epithelial migration, as does skin, but heals by deposition of cells on the wound, or proliferation from within the wound depths.

Reversible dry micro-fibrillar adhesives with thermally controllable adhesion
Soft Matter, 2009This work reports thin-film terminated micro-fibrillar adhesives made of adhesive polymers and shape memory polymers as reversible dry adhesives with thermally controllable adhesion. Structurally different adhesives were fabricated by coating a continuous thin layer of an elastomeric adhesive polymer onto either a flat or a fibrillar shape memory ...

Bioinspired Multiscale Wet Adhesive Surfaces: Structures and Controlled Adhesion
Advanced Functional Materials, 2019AbstractIn nature, many organisms are able to accommodate a complex living environment by developing biological wet adhesive surfaces with unique functions such as fixation and predation. Significantly, most of these outstanding functions originate from the specialized micro/nanostructures and/or chemical components of these natural organisms.

Redox Control of Integrin Adhesion Receptors
2002Publisher Summary Integrins are transmembrane adhesion receptors that play an essential role in normal tissue development and homeostasis. Many integrins bind to their ligands through the Arg-Gly-Asp tripeptide sequence, which is displayed by a number of extracellular matrix proteins, plasma proteins, and even viruses.

Locomotion and adhesion: dynamic control of adhesive surface contact in ants
Arthropod Structure & Development, 2004Tarsal adhesive pads of insects are highly dynamic organs that play an important role in locomotion. Many insects combine fast running performance with strong resistance to detachment forces. This capacity requires an effective control of attachment forces at the tarsus and pretarsus. Here we investigate mechanisms of attachment control in Asian weaver
