Invited for this month's cover picture is the group of Dr. Robbyn K. Anand at Iowa State University. The Front Cover shows three golden tridents hovering above a stormy sea as a representation of the interdigitated bipolar electrode (IDBPE) array discussed in this work. The offset reflection of the tridents in the water emphasizes the interdigitation of the electrodes. The red glow at the tip of the trident handle represents the light produced by the electrogenerated chemiluminescence (ECL) reaction at the reporting end of each IDBPE. The lightning that travels along the length of the trident illustrates the electronic coupling between the sensing and reporting ends of the bipolar electrode. We chose the trident to represent this electrochemical system because it evokes a sense of power, which points to the potential of the interdigitation for signal amplification.

用于增强生物传感灵敏度的交叉双极电极阵列的氧化还原循环

受邀参加本月封面图片的是爱荷华州立大学的 Robbyn K. Anand 博士小组。封面展示了三个金色三叉戟在波涛汹涌的海面上盘旋，作为本工作中讨论的叉指双极电极 (IDBPE) 阵列的代表。三叉戟在水中的偏移反射强调了电极的相互交叉。三叉戟手柄尖端的红光代表每个 IDBPE 报告端的电致化学发光 (ECL) 反应产生的光。沿着三叉戟长度传播的闪电说明了双极电极的传感端和报告端之间的电子耦合。我们选择三叉戟来代表这个电化学系统，因为它唤起了一种力量感，这指出了信号放大交错的潜力。阅读文章全文： 10.1002/celc.202100523。
