通过在肌红蛋白晶体中积累氧化还原辅因子，构建了人工光诱导电子转移系统。晶体空间允许建设一个网站特定的密集阵列，和不同的氧化还原辅因子有低重组能量，在本地光合作用中观察到的。实现了电荷分离态，其半衰期比先前报道的有机溶液中的半衰期长2800倍。
An artificial photoinduced electron-transfer system has been constructed by accumulating redox cofactors in a myoglobin crystal. The crystal space allowed the construction of a site-specific dense array, and the different redox cofactors had low reorganization energies, as observed in native photosynthesis. A charge-separated state with a half-life 2800 times longer than that of one previously reported in organic solution was achieved.
