摘要
Intracellular potassium ions(K^(+))play pivotal roles in many physiological processes.Several K^(+)sensors have been developed for probing cellular K^(+)fluctuations.Nevertheless,the existing solutions are incompatible and impractical for intracellular K^(+)probing.Herein,we report a supersmall biomimetic K^(+)nanosensor to serve as a transmembrane vector capable of electrochemically detecting intracellular K^(+)in a minimally invasive manner.
