From Wikipedia, the free encyclopedia. Electroporation, or electropermeabilization, is a molecular biology technique in which an electrical field is applied to cells in order to increase the permeability of the cell membrane, allowing chemicals, drugs, or DNA to be introduced into the cell.
Electrolysis. Photo by: Yanik Chauvin. Electrolysis is a process by which electrical energy is used to produce a chemical change. Perhaps the most familiar example of electrolysis is the decomposition (breakdown) of water into hydrogen and oxygen by means of an electric current.The same process can be used to decompose compounds other than water.Sodium, chlorine, magnesium, and aluminum are four elements produced commercially by electrolysis.erhaps the most familiar example of electrolysis is the decomposition (breakdown) of water into hydrogen and oxygen by means of an electric current.
