Gel electrophoretic mobility of charged particles in a medium with curved channels.
A model of electrophoretic mobility of small charged particles (for example short DNA fragments) in media with curved channels is proposed. The medium is represented by a dense material embedding the curved channels accessible to the charged particles. The steady flow method is used to obtain an analytical expression of the particles' electrophoretic mobility as a function of the channel's shape. The analogy between the statistical properties of the channels and polymer chains (free-jointed and with the persistent mobility mechanism) is used.
