Multisample technique to analyze cell adhesion

King Abdullah University of Science and Technology researchers have developed a robust and efficient method of examining the interactions between cells using fluorescent tagging, simultaneously analyzing multiple cell populations, ...

Surfaces that grip like gecko feet could be easily mass-produced

Why did the gecko climb the skyscraper? Because it could; its toes stick to about anything. For a few years, engineers have known the secrets of gecko stickiness and emulated it in strips of rubbery materials useful for picking ...

Adhesion

Adhesion is any attraction process between dissimilar molecular species that can potentially bring them in close contact. By contrast, cohesion takes place between similar molecules.

Adhesion is the tendency of dissimilar particles and/or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
