History of electrophoresis

The first observation of electrophoresis occurred during first years of 19th century independently by Gautherot in 1801 and by Reuss in 1809. The history of electrokinetics and electrophoresis for their most widely used applications, such as molecular separation and chemical analysis, began with the work of Arne Tiselius in 1931, while new separation processes and chemical speciation analysis techniques based on electrophoresis and electrokinetics continue to be developed in the 21st century.
