本研究将水溶性荧光碳纳米点（CND）直接注射到烟草叶片中。在紫外-蓝光转换纳米材料的帮助下，在额外的6 W紫外线照射下，叶片的光合速率提高了18%。讨论了不同种类CNDs的光稳定性和毒性。结果表明，表面带有NH 2-基团的CND在植物叶片中能保持较好的荧光性，表面基团复杂的CND对植物的毒性较高。将具有无毒和良好光稳定性的NH 2功能化的CNDs用作直接利用太阳能中的紫外光的体内光转换材料。
In this study, water-soluble fluorescent carbon nanodots (CNDs) were directly injected into the leaf of nicotiana tabacum. With the help of UV-to-blue light conversion nanomaterial, the photosynthetic rate of the leaf was improved 18% upon additional 6 W UV irradiation. The photostability and toxicity of different kinds of CNDs were discussed. The results showed that CNDs functionalized with NH2-groups on their surfaces could maintain good fluorescence in plant leaf, and CNDs with complex surface groups tended to have high toxicity to the plant. The NH2-functionalized CNDs with non-toxicity and good photostability were used as in vivo light conversion material for direct utilization of UV light in the solar energy.
