Bipolar electrochemistry—symbolized by the two electrodes at the opposite sides of the picture—can trigger the bioelectrocatalytic reduction of the important enzymatic cofactor NAD⁺, as reported by Lin Zhang, Alexander Kuhn et al. in their Communication (DOI: 10.1002/anie.202111804). The reaction occurs on the negatively polarized side—indicated by the δ⁻ sign—of surface-modified catalytically active beads—illustrated by the planets—suspended in the bulk phase of an electrolyte. This wireless electrochemical approach allows a systematic tuning of the increase in conversion efficiency.

使用双极电化学进行大量电催化 NADH 辅因子再生

正如 Lin Zhang、Alexander Kuhn 等人报道的那样，双极电化学——由图片相对两侧的两个电极表示——可以触发重要的酶促辅因子 NAD ⁺的生物电催化还原。在他们的通讯中（DOI：10.1002/anie.202111804）。反应发生在表面改性催化活性珠（由行星表示）的负极极化侧（由 δ ^-符号表示），悬浮在电解质的主体相中。这种无线电化学方法允许系统调整转换效率的增加。
