Rectification in synthetic conical nanopores: a one-dimensional Poisson-Nernst-Planck model.
Ion transport in biological and synthetic nanochannels is characterized by phenomena such as ion current fluctuations and rectification. Recently, it has been demonstrated that nanofabricated synthetic pores can mimic transport properties of biological ion channels [P. Yu. Apel, Nucl. Instrum Methods Phys. Res. B 184, 337 (2001); Z. Siwy, Europhys. Lett. 60, 349 (2002)]. Here, the ion current r...
متن کاملCurrent voltage curves in synthetic conical nanopores described by a simple Poisson / Nernst Planck model
We have developed a theoretical model [1] for ionic transport through synthetic conical nanopores. The results have been compared with experiments obtained for single, goldcoated conical nanopores. The model [1] describes quantitatively the ionic transport through synthetic conical nanopores. It is based on the Poisson and Nernst-Planck (PNP) equations and allows the calculation of realistic p...
متن کاملRectification in synthetic conical nanopores
The theoretical description of ionic transport processes in nanoporous materials is a very interesting topic, since these materials have promising technological applications e.g. in sensing and filtration of molecules with size comparable to the pore diameter, and especially single pores may serve as model systems for biological ion channels. By the track-etching method [1], it is possible to p...
متن کاملPoisson-Boltzmann-Nernst-Planck model.
The Poisson-Nernst-Planck (PNP) model is based on a mean-field approximation of ion interactions and continuum descriptions of concentration and electrostatic potential. It provides qualitative explanation and increasingly quantitative predictions of experimental measurements for the ion transport problems in many areas such as semiconductor devices, nanofluidic systems, and biological systems,...
متن کاملPoisson-Nernst-Planck model of ion current rectification through a nanofluidic diode.
We have investigated ion current rectification properties of a recently prepared bipolar nanofluidic diode. This device is based on a single conically shaped nanopore in a polymer film whose pore walls contain a sharp boundary between positively and negatively charged regions. A semiquantitative model that employs Poisson and Nernst-Planck equations predicts current-voltage curves as well as io...
