Abstract
A method for making a single molecule receptor in a nanopore structure includes depositing a material by a physical vapor deposition (PVD) technique onto a selected interior surface of a nanochannel and functionalizing a surface of the material with a chemical compound having at least two functional groups. The material forms a patch having a diameter of about 3 to about 10,000 nanometers (nm). Also disclosed are embodiments of a nanopore structure including a single molecule receptor.
