Scientists from the Institute of Scientific and
Industrial Research at Osaka University fabricated nanopores in
silicon dioxide, that were only 300 nm, in diameter surrounded by
electrodes. These nanopores could prevent particles from entering
just by applying a voltage, which may permit the development of
sensors that can detect very small concentrations of target
molecules, as well as next-generation DNA sequencing
technology.
