Ion-selective organic electrochemical transistors with sensitivity to potassium approaching 50 μA dec-1 are demonstrated. The remarkable sensitivity arises from the use of high transconductance devices, where the conducting polymer is in direct contact with a reference gel electrolyte and integrated with an ion-selective membrane.
