Abstract
Electron transfer (ET) and proton transfer (PT) events are involved in most of the biochemical processes in biology, such as within the aerobic respiration system and photosynthesis. Whereas most of the ET and PT reactions in biology are short-range on the (sub-)nanometer scale, several biological systems are capable of long-range ET or PT on the hundreds of nanometers to micrometers. This perspective summarizes which biological or bioinspired systems are capable of long-range ET or PT, which suggested mechanisms might explain long-range ET or PT together with the needed molecular basis within the biological material to allow this transport for very long distances. The fundamental difference between long-range ET and PT is discussed as well as design guidelines for new electron- or proton-conductive biological materials.
电子转移(ET)和质子转移(PT)事件参与了生物界的大多数生化过程,例如有氧呼吸系统和光合作用。虽然生物学中的大多数 ET 和 PT 反应都是(亚)纳米尺度的短程反应,但有几个生物系统能够进行数百纳米到微米的长程 ET 或 PT 反应。本视角总结了哪些生物或生物启发系统能够进行长程 ET 或 PT 反应,提出了哪些机制可以解释长程 ET 或 PT 反应,以及生物材料中允许这种长程传输所需的分子基础。本文讨论了长程电子传输和长程质子传输之间的根本区别,以及新型电子或质子传导生物材料的设计指南。
期刊介绍:
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
