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.
摘要
我们报道了首次使用基于构象变化的电化学适体传感器进行选择性钾离子识别，该传感器通过方波伏安法或电化学阻抗谱以电化学方式转导电信号。
