Adsorption is often described as a surface phenomenon where particles are attached to the top layer of material. The process of removal of an adsorbed substance from a surface on which it is absorbed is called desorption.

Adsorption is often described as a surface phenomenon where particles are attached to the top layer of material. It normally involves the molecules, atoms or even ions of a gas, liquid or a solid in a dissolved state that is attached to the surface. Adsorption is a process which involves the accumulation of a substance in molecular species in higher concentration on the surface.

What is electrophoresis?

Charged macromolecules are placed in the electric field move towards the negative or positive pole based on their charge. Nucleic acid has a negative charge and therefore it migrates towards the anode. It has a wide application in separating and analysing biomolecules such as proteins, plasmids, RNA , DNA , nucleic acids. This technique is divided into two types viz slab electrophoresis and capillary electrophoresis.
