Abstract

A method for making multiple single molecule receptors in a nanopore structure includes depositing a first material and a second material by a physical vapor deposition (PVD) technique onto different selected interior surfaces of a nanochannel and functionalizing a surface of the first material, the second material, or both the first and second materials with a chemical compound having at least two functional groups. The first and second materials can be the same or different and form patches having diameters of about 1 to about 100 nanometers (nm). Also disclosed are embodiments of a nanopore structure including multiple single molecule receptors.

First claim

What is claimed is:

1. A nanopore structure comprising multiple single molecule receptors, the nanopore structure comprising:
a substrate having a first surface and an opposing second surface;
a nanochannel extending from the first surface to the opposing second surface and defining an interior surface;
a first material disposed onto a selected area of the interior surface of the nanochannel, the first material forming a first patch having a surface area of about 3 to about 10…
