1. A method comprising:
- a) placing a plurality of labeled proteins, polypeptides or peptides in a plurality of chambers, such that different chambers contain a different type of labeled amino acid;
b) passing the labeled proteins, polypeptides or peptides through one or more nanopores, an inner surface of the nanopores coated with a semiconductor material;
c) detecting labeled amino acid residues in the labeled proteins, polypeptides or peptides;
d) compiling an amino acid distance map for each type of labeled amino acid; and
e) identifying the protein based on the distance maps.

Abstract
The methods and apparatus, disclosed herein are of use for sequencing and/or identifying proteins, polypeptides and/or peptides. Proteins containing labeled amino acid residues may be synthesized and passed through nanopores. A detector operably coupled to a nanopore may detect labeled amino acid residues as they pass through the nanopore. Distance maps for each type of labeled amino acid residue may be compiled. The distance maps may be used to sequence and/or identify the protein. Apparatus of use for protein sequencing and/or identification is also disclosed herein. In alternative methods, other types of analytes may be analyzed by the same techniques.
