New and enhanced functions were potentially imparted to the plant organelles after interaction with nanoparticles. In this study, we found that ∼ 44% and ∼ 29% of the accumulated graphene in the rice leaves passively transported to the chloroplasts and thylakoid, respectively, significantly enhanced the fluorescence intensity of chloroplasts, and promoted about 2.4 times higher adenosine triphosphate production than that of controls. The enhancement of graphene on the photophosphorylation was ascribed to two reasons: One is that graphene facilitates the electron transfer process of photosystem II in thylakoid, and the other is that graphene protects the photosystem II against photo-bleaching by acting as a scavenger of reactive oxygen species. Overall, our work here confirmed that graphene translocating in the thylakoid promoted the photosynthetic activity of chloroplast in vivo and in vitro, providing new opportunities for designing biomimetic materials to enhance the solar energy conversion systems, especially for repairing or increasing the photosynthesis activity of the plants grown under stress environment.

与纳米粒子相互作用后，可能会将新的和增强的功能赋予植物细胞器。在这项研究中，我们发现分别被动转移到叶绿体和类囊体的水稻叶片中分别约有44％和29％的积累的石墨烯显着增强了叶绿体的荧光强度，并比三磷酸腺苷的产量提高了约2.4倍。控件。石墨烯在光磷酸化上的增强归因于两个原因：一个是石墨烯促进类囊体中光系统II的电子转移过程，另一个是石墨烯通过充当活性氧清除剂来保护光系统II免受光致漂白。种类。总体，在体内和体外，为设计仿生材料以增强太阳能转换系统提供了新的机会，特别是修复或增加了在胁迫环境下生长的植物的光合作用活性。
