氧化还原酶和电极表面之间的有效电子转移可以通过使用例如聚合物结合的氧化还原继电器连接氧化还原酶来获得，这已经被证明是电流生物传感器、逻辑门或传感器阵列的设计基础，并且更一般地被证明是“生物电化学”的中心方面。相关装置允许利用酶的独特催化性质，其中光合酶由于在用光照射时触发氧化还原反应的可能性而特别有吸引力。光催化性质，如光驱动的光系统2分解水，使它们成为开发半人工装置的独特候选者，这些装置将光能转化为稳定的化学产品，如氢气。本文综述了光系统1和光系统2整合到生物电化学器件的最新概念，特别关注氧化还原酶和导电载体之间的电子转移途径的设计策略。
The efficient electron transfer between redox enzymes and electrode surfaces can be obtained by wiring redox enzymes using, for instance, polymer-bound redox relays as has been demonstrated as a basis for the design of amperometric biosensors, logic gates or sensor arrays and more general as a central aspect of "bioelectrochemistry". Related devices allow exploiting the unique catalytic properties of enzymes, among which photosynthetic enzymes are especially attractive due to the possibility to trigger the redox reactions upon irradiation with light. Photocatalytic properties such as the light-driven water splitting by photosystem 2 make them unique candidates for the development of semiartificial devices which convert light energy into stable chemical products, like hydrogen. This review summarizes recent concepts for the integration of photosystem 1 and photosystem 2 into bioelectrochemical devices with special focus on strategies for the design of electron transfer pathways between redox enzymes and conductive supports.
