Dispersive Forces
Adhesion Through van der Waals and Casimir Forces

The phenomena of adhesion and cohesion play an important role in many areas of science and technology. They are responsible for stiction-related failure in microelectromechanical devices; microbial adhesion is responsible for the formation of biofilms; and they contribute to friction and wear between surfaces. Adhesion and cohesion can be loosely defined as the molecular attraction that holds together surfaces of two different substances or two identical substances, respectively. Of the interactions that are responsible for adhesion and cohesion, the van der Waals or Casimir interaction is universal and exists between all types of atoms as well as macroscopic objects.
