Illustration o electrophoresis

Electrophoresis is the motion o dispersed particles relative tae a fluid unner the influence o a spatially uniform electric field.[1][2][3][4][5][6] This electrokinetic phenomenon wis observed for the first time in 1807 by Ferdinand Frederic Reuss (Moscow State Varsity),[7] who noticed that the application o a constant electric field caused clay pairticles dispersed in watter tae migrate. It is ultimately caused bi the presence o a charged interface atween the pairticle surface an the surroondin fluid. It is the basis for a nummer o analytical techniques uised in biochemistry for separatin molecules bi size, charge, or bindin affinity.

Electrophoresis o positively charged pairticles (cations) is cried cataphoresis, while electrophoresis o negatively charged pairticles (anions) is cried anaphoresis.
