The Front Cover illustrates the amplification of an electrochemiluminescent signal by redox cycling in the context of bipolar electrochemistry. Each of the three golden tridents represents a bipolar electrode; the prongs correspond to microband ′digits′ that facilitate redox cycling of an analyte with a shared driving electrode, and the handle portrays the electrode pole at which the luminescent reporting reaction occurs. The electronic coupling of these two reactions is depicted by the lightning along each trident. More information can be found in the Article by Janis S. Borchers et al.

封面：在一系列叉指双极电极上进行氧化还原循环以提高生物传感的灵敏度（ChemElectroChem 18/2021）

封面说明了在双极电化学背景下通过氧化还原循环放大电化学发光信号。三个金色三叉戟中的每一个代表一个双极电极；尖头对应于微带“数字”，通过共享驱动电极促进分析物的氧化还原循环，手柄描绘了发生发光报告反应的电极极。这两个反应的电子耦合由沿着每个三叉戟的闪电描述。更多信息可以在 Janis S. Borchers 等人的文章中找到。
