In nature, ion channels are highly selective pores and act as gate to ensure selective ion transport, allowing ions to cross the membrane. By mimicking them, single solid state nanopore devices emerge as a new, powerful class of molecule sensors that allow for the label-free detection of biomolecules (DNA, RNA, and proteins), non-biological polymers, as well as small molecules. In this review, we exhaustively describe the fabrication and functionalization techniques to design highly robust and selective solid state nanopores. First we outline the different materials and methods to design nanopores, we explain the ionic conduction in nanopores, and finally we summarize some techniques to modify and functionalize the surface in order to obtain biomimetic nanopores, responding to different external stimuli.
