Bionanotechnology: Zero‐Depth Interfacial Nanopore Capillaries (Adv. Mater. 9/2018)

In article number 1703602, Grégory F. Schneider and co‐workers report nanocapillaries of zero depth, which are formed by dissolving two superimposed and crossing metallic nanorods, molded in polymeric slabs. In an electrolyte, the interface shared by the crossing fluidic channels is mathematically of zero thickness and defines the narrowest constriction in the stream of ions through the nanopore device. Interfacial nanopores are hereby established as a scalable platform for realizing nanofluidic systems, capable of single‐molecule detection.
