Chemical Functionalization of Solid-State Nanopores and Nanopore Arrays and Applications Thereof

Abstract

Chemical functionalization of solid-state nanopores and nanopore arrays and applications thereof. Nanopores are extremely sensitive single-molecule sensors. Recently, electron beams have been used to fabricate synthetic nanopores in thin solid-state membranes with sub-nanometer resolution. A new class of chemically modified nanopore sensors are provided with two approaches for monolayer coating of nanopores by: (1) self-assembly from solution, in which nanopores −19 nm diameter can be reproducibly ceased, and (2) self-assembly under voltage driven electrolyte flow, in which 5 nm nanopore may be coated. Applications of chemically modified nanopore are provided including, the detection of biopolymers such as DNA and RNA, immobilizing enzymes or other proteins for detection or for generating chemical gradients; and localized pH sensing.
