A review is made, with the aim of unifying various apparently disparate sensing strategies. The unifying feature is the underlying measurement principle that entails occlusion of an aperture through which a current is passing by the analyte species. The review focuses on two very recent manifestations of this sensing paradigm: the use of protein-based channels and nanotube membranes for small molecule and ion sensing.
