Nanopore devices

Definition

Nanopore devices are small-scale technologies that utilize nanopores—tiny holes typically ranging from 1 to 100 nanometers in diameter—to manipulate and analyze fluids at the nanoscale. These devices are significant for their ability to study single molecules, such as DNA and proteins, allowing for real-time analysis and characterization of biological processes. Their unique capabilities make them invaluable for applications like genomic sequencing and advanced manufacturing techniques.
