The sensing device. (a) The prototype nanofluidic device based on integrated micro-nano pore for biosensing. The left cell in which the biomolecules are added is the feed cell, and the right cell is the permeation cell. (b) The designed sensing devices were built using only PC nanopore membrane for ionic current detection. (c) The designed sensing devices containing PC nanopore membrane integrated with Si3N4-Si hybrid micropore structure for biomolecule sensing.
