A capacitive sensing system (2, 2', 2'') is used to measure a timevarying ion current through a channel (50), such as an ion channel or protein pore. Such a capacitive system (2, 2', 2'') does not suffer problems of electrode corrosion and, when used with methods to control a build up of ion concentration, allows the use of measurement volumes (10, 20) around the channel (50) with dimensions on a scale of nanometers. |
