Abstract

Techniques for controlling the position of a charged polymer inside a nanopore are provided. For example, one technique includes using electrostatic control to position a linear charged polymer inside a nanopore, and creating an electrostatic potential well inside the nanopore, wherein the electrostatic potential well controls a position of the linear charged polymer inside the nanopore.
