When bioelectrochemistry meets other analytical techniques for in situ experiments, new possibilities for understanding the nature of charge‐transfer reactions are provided. Despite progress in recent years in analytical instrumentation, a number of key issues remains for bioelectrochemistry, in terms of the mechanistic description of the surface reactions involved in biomolecules’ electron transfer. The main challenges of these techniques are the concomitant detection of electron transfer and molecular alteration as well as the development of suitable bioelectrodes. This review discusses the most recent and emerging in situ and operando electrochemical methods used to study biological systems such as redox proteins, nucleic acids, small biomolecules, cells, and biomembranes, focusing on electrochemical methods coupled with spectroscopic, spectrometric, and microscopic techniques.

用于研究生物系统中电子转移的原位和Operando技术

当生物电化学遇到其他用于原位实验的分析技术时，提供了新的理解电荷转移反应性质的可能性。尽管近年来在分析仪器方面取得了进展，但就生物分子电子转移所涉及的表面反应的机理描述而言，生物电化学仍然存在许多关键问题。这些技术的主要挑战是伴随着电子转移和分子变化的检测以及合适生物电极的开发。这篇评论讨论了最新和新兴的原位和手术用于研究生物系统（例如氧化还原蛋白，核酸，小生物分子，细胞和生物膜）的电化学方法，重点是结合光谱学，光谱学和显微技术的电化学方法。
