Cover Story: The general theory is developed for the transient electrophoresis of a colloidal particle in a polymer gel medium. The Laplace transform of the particle electrophoretic mobility with respect to time is derived by considering the long-range hydrodynamic interaction between the particle and the polymer gel medium. According to the obtained Laplace transform, the transient gel electrophoretic mobility approaches the steady gel electrophoretic mobility as time approaches infinity. The present theory covers the transient free-solution electrophoresis. It is shown that the relaxation time for the transient gel mobility to reach its steady value is shorter than that of the transient free-solution mobility and becomes shorter as the Brinkman screening length decreases.
