摘要	A molecular dynamics study of the electrophoresis of bottle-brush polyelectrolytes (BPEs) through nanochannels is reported. The BPE molecules consist of a neutral backbone with charged side chains. For strong attractive interactions between the BPE and the wall, the BPE is being trapped on the channel surface. A stretchingshrinking migration of the BPE in a channel of radius 6s is observed at relatively strong electric fields. The stretchingshrinking transition is periodic for intermediate electric fields but not for stronger electric fields. The BPE also shows a transverse migration toward the wall at weak electric fields, while toward the center with further enhancing the electric field. For a channel with larger radius 12s, the BPE does not migrate in the stretchingshrinking manner.
