4-72 Interpretation of the Recti cation of Single Conical Nanopores

摘要

Due to the symmetry breaking,single conical nanopores show characteristics of ion-current rectification,which has a great potential in applications to ion separation,power supplier and chemical valve[-5].It is of great importance to study the electrical properties of nanopores and the modification methods of conical nanopores in order to understand the ion transport properties in nanoscale structures and to improve the application performance of conical nanopores.
