A charged solid nanoparticle covered with a permeable layer is a common example of natural nanosubstances such as biocolloids. Studying the translocation of such a particle along a nanochannel will provide a better understanding of such natural phenomena. With the emergence of a wide range of applications such as sequencing, separation, extraordinarily small volume chemical delivery, using nano-scale channel-like structures, it has become essential to adjust the velocities of the substances translocating through these nanostructures. In this study, the translocation of a charged solid nanoparticle through a nanochannel filled with an aqueous electrolyte solution, activated electrophoretically by an applied electric potential effect, was numerically investigated. Poisson-Nernst-Planck model, and modified Stokes and Brinkman equations were used for numerical solution. The ionic layer formed around the charged particle and the outer region of this layer were examined separately in terms of hydrodynamics, by applying different mathematical models. It was observed that the electrophoretic velocity of the nanoparticle strongly depends on the charged permeable layer formed around it. © 2021 IEEE.eninfo:eu-repo/semantics/closedAccesselectrophoresisnanochannelnumerical continuum modelspherical particleConference Object10.1109/ISMSIT52890.2021.96046662672712-s2.0-85123289356N/A
