Abstract

The invention belongs to the technical field of nanopore functionality, and discloses a nanopore functional control method and system. Nanopores are manufactured through a nanopore preparation module, and a molecular construction solution is prepared through a molecular construction solution preparation module. A solution of a construct is introduced to the substrate, the molecular construct having a body structure defining a pore and tail structures extending from the body structure. In the present invention, the molecular construct is docked onto the substrate by applying a potential difference across the substrate through a pair of potential application modules to cause the tail structure to pass through the nanopore, wherein the hole is paired with the nanopore aligning; and removing the molecular construct from the substrate by changing the potential difference through a potential applying module.

Description

technical field [0001] The invention belongs to the technical field of nanopore functionality, and in particular relates to a nanopore functional control method and system. Background technique [0002] Currently, single nanopores in insulating layers are under investigation as single-molecule sensors in solution1. Research activity in nanopore sensing has grown rapidly since the first experiments on DNA and RNA translocation by Kasianowicz et al. Single solid-state nanopores fabricated by silicon nanotechnology and ion milling have been applied for the first time in ionic current-based DNA detection. DNA folding detection using nanocapillaries, development of selective fabrication schemes such as transmission-electron drilling of solid-state nanopores, or nanopores with other single-molecule technologies such as optical tweezers, magnetic tweezers or single-molecule fluorescence, has given new impetus to the field. In a typical application, the nanopore separates two cha...
