Abstract

Inspired by the biological ion channels, DNA supersandwich structures were self-assembled in diamond-shaped mica nanopores, forming highly efficient gate-like nanofluidic switch. Through asymmetric DNA modification in the mica nanopores, rectified ion transport property was observed. The results revealed that DNA, the flexible biological molecules, can also be used to build nanofluidic devices for gating and rectification function in solid-state nanopores with parallel tetrahedron structures.
