Query: Electrophoretic Mobility of Polyelectrolytes within a Confining Well   We present a numerical study of polyelectrolytes electrophoresing in free
solution while squeezed by an axisymmetric confinement force transverse to
their net displacement. Hybrid multi-particle collision dynamics and molecular
dynamics simulations with mean-field finite Debye layers show that even though
the polyelectrolyte chains remain "free-draining", their electrophoretic
mobility increases with confinement in nanoconfining potential wells. The
primary mechanism leading to the increase in mobility above the free-solution
value, despite long-range hydrodynamic screening by counterion layers, is the
orientation of polymer segments within Debye layers. The observed
length-dependence of the electrophoretic mobility arises due to secondary
effects of counterion condensation related to confinement compactification.
