Aptamer conformational switch as sensitive electrochemical biosensor for potassium ion recognition.

Abstract

We report the first use of an electrochemical aptasensor for selective potassium recognition, based on a conformational change, affording an electric signal transduced electrochemically by square wave voltammetry or electrochemical impedance spectroscopy.
