Using nanopore DNA sequencing technology, researchers have managed to scan a single protein: by slowly moving a linearized protein through a tiny nanopore, one amino acid at the time, the researchers were able to read off electric currents that relate to the information content of the protein. The new single-molecule peptide reader marks a breakthrough in protein identification, and opens the way towards single-molecule protein sequencing and cataloguing the proteins inside a single cell.
