Abstract
A capacitive sensing system is used to measure a time-varying ion current through a channel, such as an ion channel or protein pore. Such a capacitive system 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 around the channel with dimensions on a scale of nanometers.
