A peptide nanotube platform that integrates both light-harvesting and catalytic units was successfully engineered for artificial photosynthesis. Peptide nanotubes not only serve as a hub for physically combining both units, but also work as mediators that transfer the energy from photo-excited chromophores to catalytic centers. The direct conversion of NAD(+) to NADH upon light illumination was demonstrated. This represents a promising step towards efficient and fully integrated artificial photosynthesis systems.
成功设计了一种将光捕获和催化单元集成在一起的肽纳米管平台，用于人工光合作用。肽纳米管不仅作为物理结合这两个单元的中心，还作为将能量从光激发的生色团转移到催化中心的介质。证明了在光照射下 NAD(+)直接转化为 NADH。这是朝着高效、完全集成的人工光合作用系统迈出的有希望的一步。
