SYSTEMS AND METHODS FOR POLYMER CHARACTERIZATION

摘要

Techniques for controlling the position of a charged polymer (112) inside a nanopore (105) 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 (114) inside the nanopore, whereby the electrostatic potential well controls the position of the linear charged polymer inside the nanopore. By sequentially locking each monomer unit in the potential well (114), nanopore sequencing of DNA with single base resolution can be achieved.
