Shutting the nano-gate – EurekAlert
Osaka University scientists used circular gate electrodes set around tiny nanopores to hold particles just outside the opening, or make them pass through very slowly….

Osaka, Japan – 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…
