利用各种光谱技术研究了附着于金属表面的干光系统蛋白质I的光电性质。化学吸附后的蛋白质被发现是光学活性。此外，能量分辨光电测量表明，光系统I与金属表面的相互作用导致新的分子/底物状态，产生不同于单个组分的能量状态。这种相互作用增加了光谱I-响应范围超出光系统I的吸收光谱，并有望提高基于该系统的器件的能量转换效率。
The photoelectronic nature of a dried photosystern I protein attached to a metal surface is studied using various spectroscopic techniques. The proteins are found to be optically active after the chemical adsorption. In addition, energy-resolved photoelectronic measurements indicate that the interaction of photosystem I with the metal surface leads to new molecule/substrate states, yielding energy states different from those of the individual components. Such interactions increase the spectra I-response range beyond the absorption spectrum of photosystem I and are expected to improve the energy-conversion efficiency of devices based on this system.
