Surface chemistry plays a significant part in terms of interactions with the human tissue.
Surface tension can be measured with force tensiometer using Du Noüy ring or Wilhelmy plate. Or with optical tensiometer using the pendant drop method.
Du Noüy method utilizes the interaction of a platinum ring with the surface of the liquid.
The surface tension of water is about 72 mN/m at room temperature which is one of the highest surface tension for liquid.
Langmuir film can be defined as an insoluble monolayer of atoms, molecules, or even nanoparticles floating at the liquid-gas interface (or liquid-liquid).
Work of adhesion is defined as a work required to separate two phases from each other.
Wenzel equation states that adding surface roughness will enhance the wettability caused by the chemistry of the surface.
Interactions at the material surface is influenced by the wettability of the material. Wettability measurements are done to evaluate biocompatibility.
Adhesion plays an important role in daily and industrial processes. Adhesion can be either wanted or unwanted.
