生物大分子中的电子转移现象是生命科学中最重要的过程之一。到目前为止，存在有限数量的微观研究，大多数知识都是基于宏观研究。为了克服这种情况，最近开发了一种带有正μ子的标记电子方法，并成功地应用于直接探索代表性蛋白质（如细胞色素c、肌红蛋白和细胞色素c氧化酶以及DNA）中的微观电子转移现象。的原则，每个实验的一些细节和未来的前景进行了描述。
Electron-transfer phenomena in biological macromolecules are among the most important processes of life science. So far, a limited number of microscopic studies exist, and most knowledge is based on macroscopic studies. In order to overcome this situation, a labelled electron method with positive muons was recently developed and successfully applied to directly explore microscopic electron-transfer phenomena in representative proteins, such as cytochrome c, myoglobin and cytochrome c oxidase, and DNA. The principle, some details of each experiment and future perspectives are described.
