Nature Biotechnology, Published online: 09 January 2023; doi:10.1038/s41587-022-01599-2Sequencing of proteins is a technically difficult task that typically requires digestion into short peptides before detection and identification. We developed a digestion-free method to chemically unfold and ‘scan’ full-length proteins through a nanopore, producing electrical fingerprints unique to individual protein molecules that are useful in their identification…
