We present a scaling behavior of a rectifying bipolar nanopore as a function of the parameter ξ = RP/(λzif), where RP is the radius of the pore, λ is the characteristic screening length of the electrolyte filling the pore, and zif=z+|z−| is a scaling factor that makes scaling work for electrolytes containing multivalent ions (z+ and z– are cation and the anion valences). By scaling we mean that the rectification of the pore (defined as the ratio of currents in the forward and reversed biased…

Scaling for rectification of bipolar nanopores as a function of a modified Dukhin number: the case of 1:1 electrolytes
ABSTRACT The scaling behaviour for the rectification of bipolar nanopores is studied using the Nernst-Planck equation coupled to the Local Equilibrium Monte Carlo method. The bipolar nanopore's wall
Rectification of bipolar nanopores in multivalent electrolytes: effect of charge inversion and strong ionic correlations.
This modeling study uses both the mean-field Poisson-Nernst-Planck (PNP) theory and a particle simulation method, Local Equilibrium Monte Carlo (LEMC), to show that phenomena such as overcharging and charge inversion cannot be reproduced with PNP, while LEMC is able to produce nonmonotonic dependence of currents and rectification as a function of surface charge strength.
From nanotubes to nanoholes: Scaling of selectivity in uniformly charged nanopores through the Dukhin number for 1:1 electrolytes.
This modeling study using the Local Equilibrium Monte Carlo method and the Poisson-Nernst-Planck theory provides concentration, flux, and selectivity profiles that show whether the surface or the volume conduction dominates in a given region of the nanopore for a given combination of the variables.
Modeling the Device Behavior of Biological and Synthetic Nanopores with Reduced Models
Four rules of thumb are proposed for constructing good reduced models of ion channels and nanopores that focus on the physics that produces the device functions rather than the atomic/molecular-scale physics inside the pore.
Electrical conductance of charged nanopores
A nanopore’s response to an electrical potential drop is characterized by its electrical conductance, G. It has long been thought that at low concentrations, the conductance is independent of the

Nanochannels offer significant practical advantages in many fields due to their interesting characteristics, such as flexibility in shape and size, robustness, low‐cost and their ability to be


Controlling ion transport through nanopores: modeling transistor behavior.
Qualitative agreement between PNP and LEMC results indicates that mean-field electrostatic effects predominantly determine device behavior and the scaling behavior of the device as a function of the Rpore/λD parameter.
Rectification of Ion Current in Nanopores Depends on the Type of Monovalent Cations: Experiments and Modeling
All-atom molecular dynamics simulations revealed differential binding between Li+, Na+, and K+ ions and carboxyl groups on the pore walls, resulting in changes to both the effective surface charge of the nanopore and cation mobility within the pores.
Multiscale modeling of a rectifying bipolar nanopore: Comparing Poisson-Nernst-Planck to Monte Carlo.
Current data is presented that characterize the nanopore's behavior as a device, as well as concentration, electrical potential, and electrochemical potential profiles, which are appropriate to reproduce the basic behavior of the bipolar nanopore.
The effects of electrostatic correlations on the ionic current rectification in conical nanopores
By considering the electrostatic correlations, the modified PNP model successfully captures the ionic current rectification reversal in nanopores filled with lanthanum chloride LaCl3, suggesting that ion‐ion electro static correlations are responsible for this reversal behavior.

Under certain conditions the rectification degree, defined as a ratio of currents recorded at the same voltage but opposite polarities, can reach values of over 1000 at a voltage range <-2 V,+2 V>.

The measurements of ionic conductance in single, synthetic nanometer-diameter pores are consistent with the presence of fixed negative charge in the pore wall and a reduction of the ion mobility because of the fixed charge and the ion proximity to the por wall.

Asymmetric-Fluidic-Reservoirs Induced High Rectification Nanofluidic Diode
A novel nanofluidic diode that produces rectification factors in excess of 1000 and asymmetry is produced by having the nanopores join a micropore and a macropore, which is easy to scale up to industrial level.
Multiscale analysis of the effect of surface charge pattern on a nanopore's rectification and selectivity properties: From all-atom model to Poisson-Nernst-Planck.
It is found that the values of the diffusion coefficients are sensitive to the net charge of the pore but are relatively transferable to different voltages and charge patterns with the same total charge.
