荧光碳点调控植物光合作用研究进展

Progress of Carbon Dots Regulating Plant Photosynthesis

碳点(CDs)作为一种碳基纳米材料,因其粒径小、水溶性好、生物相容性高、无毒性、制备简便、原料来源广等优势,吸引了众多研究人员的关注,已在医学成像技术、环境监测、化学分析、催化剂制备、能源开发等诸多领域表现出较好的应用前景。近些年,CDs开始被应用于农业领域,尤其对植物光合作用具有优异的调控作用。一方面,CDs具有良好的光学性能,可以向叶绿体传递能量或转换光能,提高光合电子的传递速率,进而加快光合作用中光能向活跃的化学能的转化。另一方面,CDs还可以促进植物叶绿素的合成、上调光合作用相关酶的活性,提高植物对光能的捕获能力以及对CO_(2)的固定速率。鉴于CDs在农业生产中的应用前景,本文从CDs的性质和植物的生理过程出发,系统地综述了CDs在调控植物光合作用中的研究进展,并对目前限制CDs应用的问题进行了总结,为其未来的发展提供了参考。

Carbon dots(CDs),a kind of carbon nanomaterials,have various superiorities,such as small size,good water solubility,high biocompatibility,non-tixicity,simple preparation,and wide raw material sources,thereby attracting more and more attentions from researchers in medical imaging technology,environmental monitoring,chemical analysis,catalyst preparation,energy development.In recent years,CDs have begun to be applied in the field of agriculture,especially in regulating the plant photosynthesis.On the one hand,CDs,due to their good optical properties,can transfer energy or convert light to chloroplasts to improve the electron transport rate,thus accelerating the transformation of light energy to active chemical energy in photosynthesis.On the other hand,CDs can also promote the synthesis of chlorophyll and the activity of photosynthesis-related enzymes,thereby improving the ability of plants to capture light energy and CO_(2) assimilation.In view of the application prospect of CDs in agriculture,this paper systematically reviewed the research progress of CDs in regulating plant photosynthesis based on the property of CDs and the physiological process of plants.Subsequently,the current problems restricting the application of CDs were summarized.This paper provides reference for the future development of CDs in agriculture.
