摘要

We present the solutions of the interaction energy for a colloid system with a charged rod-like macromolecule immersed in a bulk electrolyte and moving along the axis of a circular orifice or disk (orifice/disk).The calculation requires a numerical computation of the surface charge profiles,which result from a constant surface potential on the macromolecule and the orifice/disk.In the calculation,remarkable divergences of the surface charge emerge on the edges of the macromolecule and the orifice/disk,which...
