abstract

• The physical phenomenon of overcharging in a charged cylindrical nanopore, immersed into a model macroions solution, is theoretically studied. We find that a novel Overcharging-Non-overcharging transition curve exists. The overcharging and non-overcharging regions are displayed in terms of the macroions valence and the nanopore%27s electrical charge. The nature of this transition is analyzed and discussed in terms of the concentration profiles of the ionic species present inside and outside of the nanopore. In our calculations, we assume that the macroions species are only present outside of the nanopore. © 2022 Elsevier B.V.
