Nanopore sensing technology can be miniaturised into a portable device for electronic single-molecule sensing.
The MinION device is a small instrument that is compatible with consumable flow cells containing the proprietary sensor chip, Application-Specific Integrated Circuit (ASIC) and nanopores that are needed to perform a complete single-molecule sensing experiment. Plugging directly into a laptop or desktop computer through a USB port, it is a self-contained device to deliver real-time experimental data.
