Electrophoresis is the motion of
dispersed particles relative to a fluid under the influence of a spatially
uniform electric field. Electrophoresis of positively charged particles
(cations) is sometimes called cataphoresis, while electrophoresis of negatively
charged particles (anions) is sometimes called anaphoresis.
The electrokinetic phenomenon of
electrophoresis was observed for the first time in 1807 by Russian professors
Peter Ivanovich Strakhov and Ferdinand Frederic Reuss at Moscow State
University, who noticed that the application of a constant electric field
caused clay particles dispersed in water to migrate. It is ultimately caused by
the presence of a charged interface between the particle surface and the
surrounding fluid. It is the basis for analytical techniques used in chemistry
for separating molecules by size, charge, or binding affinity.
