Nanopores

Nanopore-based sensors allow DNA and other biomolecules to be analysed with subnanometre resolution and without the need for labels or amplification. Researchers are working on naturally occurring biological nanopores, solid-state nanopores and hybrids of the two, along with a variety of new readout methods. The ultimate goal of this research is to be able to rapidly and reliably sequence the human genome for under $1,000. This web focus brings together all the articles that Nature Nanotechnology has published on various aspects of nanopores and their applications.
