The object
Hagan Bayley developed engineered protein nanopores for single-molecule sensing and founded Oxford Nanopore, whose MinION made DNA and RNA sequencing portable. Oxford says Bayley's laboratory demonstrated nanopore sensing in the early 1990s; his current Oxford profile describes continued nanopore engineering and 2025 publications.
What Hagan did
Developed engineered protein nanopores for single-molecule sensing and founded Oxford Nanopore, which commercialized the technology in portable sequencing devices.
Why it matters
The MinION turned nanopore sensing into a compact commercial instrument that can sequence DNA and RNA outside a conventional sequencing laboratory.
Living-status check
Oxford's current faculty page lists Bayley as Professor of Chemical Biology and records publications by him in October 2025.
