The forces acting between two surfaces in contact or near - contact determine the behavior of a wide spectrum of physical properties. These can include friction, lubrication, the flow properties of particulate dispersions, and, in particular, the adsorption and adhesion phenomena, the stability of colloidal system [1,2] and the ability to form Langmuir monolayer at the air - water interface. 

The location of a molecule at the interface between two immiscible fluids may lead to a variety of organizational and dynamic interfacial behavior dependent on the relatively of the components of the chemical structure of the molecule in each of the

For example, it is believed that polysaccharides incorporated into the membrane of a cell are responsible for the cell adhering onto a surface, and, in different area, polymers adsorbed onto surfaces play an important role in stabilizing industrial colloidal dispersions such as paints and inks.
