The model employs a self-consistent Poisson-Boltzmann scheme for the interaction among ions, charge carriers around the pore rim, and biomolecules. In combination with experimental study and molecular dynamics (MD) calculation, a comprehensive physical analysis of various resistive effects involved in the electronic detection of a single biomolecule in a nanopore of a MoS2 nanoribbon is presented.
