Abstract

Nanophotoresponsive technology has emerged as a promising way to enhance plant photosynthesis, but it faces limitations in light absorption and electron transfer efficiency. This study presents a photoresponsive nanosystem, LDNPs@Fe,Cu-CDs, combining lanthanide-doped nanoparticles (LDNPs) and Fe/Cu dual single-atom-doped carbon dots (CDs). Fabricated via hydrothermal synthesis, the nanosystem can regulate plant growth through light absorption, photothermal effects, photoelectron generation, and photocatalysis. Using a simple surface spraying method, the LDNPs@Fe,Cu-CDs can be absorbed by leaves and transported into N. benthamiana. LDNPs@Fe,Cu-CDs can harvest both near-infrared and ultraviolet light for photosynthesis and promote electron transfer in the photosynthetic chain by 33.2%. The nanosystem increased chlorophyll levels by 28.4% and enhanced photosynthesis by 67.5%. Additionally, it can alleviate the limitations of reactive oxygen species and cold environments, improving plant growth. The wet and dry weight of N. benthamiana were increased by 57.7% and 50.5%, respectively. LDNPs@Fe,Cu-CDs show great potential as a “nanophotofertilizer” for agricultural applications.

用于植物多调控生长的高光子收获纳米光肥

纳米光响应技术是一种很有前途的增强植物光合作用的方法，但它在光吸收和电子转移效率方面存在局限性。本研究提出了一种光响应纳米系统LDNPs@Fe，Cu-CDs，结合了镧系掺杂纳米粒子（LDNPs）和Fe/Cu双单原子掺杂碳点（CDs）。通过水热合成法制备的纳米系统可以通过光吸收、光热效应、光电子产生和光催化来调节植物的生长。采用简单的表面喷涂方法，LDNPs@Fe，Cu-CDs可被叶片吸收并转运到benthamiana中。LDNPs@Fe，Cu-CDs可以收集近红外光和紫外光用于光合作用，促进光合链中的电子转移33.2%。纳米系统使叶绿素含量提高28.4%，光合作用提高67.5%。此外，它还可以缓解活性氧和寒冷环境的限制，促进植物生长。处理后，本拟虫的湿重和干重分别提高了57.7%和50.5%。LDNPs@Fe，Cu-CDs作为一种“纳米光肥”在农业上的应用显示出巨大的潜力。
