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.
Claims14
A method for making a single molecule receptor in a nanopore structure, the method comprising:
- depositing a material by a physical vapor deposition (PVD) technique onto a selected interior surface of a nanochannel, the material forming a patch having a diameter of about 1 to about 100 nanometers (nm);
- and
- functionalizing a surface of the material with a chemical compound having at least two functional groups.
A method for making a single molecule receptor in a nanopore structure, the method comprising:
- tilting the nanopore structure at an angle with respect to a beam to position the beam onto a selected interior surface of a nanochannel in the nanopore structure, the beam being operative to deposit a material by a PVD technique;
- operating the beam to deposit the material onto a selected interior surface of the nanochannel, the material forming a patch having a surface area of about 3 to about 10,000 nm2;
- and
- functionalizing a surface of the patch to form the single molecule receptor.
