纳米技术被认为是增强植物光合作用的新兴有效手段。然而，该领域仍有大量工作要做。在这里，我们将上转换纳米粒子（UCNP）应用在生菜叶子上，发现 UCNP 能够运输到生菜体内并与叶绿体共定位。事实证明，UCNPs可以收获太阳光的近红外光，增加光合作用过程中的电子传递速率，从而提高光合作用速率。基因表达分析表明，光合作用90%以上的基因表达上调。将UCNP溶液喷洒在生菜叶片上并置于阳光下放置1周后，叶片的湿/干重分别增加了53.33%和45.71%。这种光捕获 UCNP 的纳米工程可能在农业中具有巨大的应用潜力。
Nanotechnology is considered as an emerging effective means to augment plant photosynthesis. However, there is still a lot of work to be done in this field. Here, we applied the upconversion nanoparticles (UCNPs) on lettuce leaves and found that the UCNPs were able to transport into the lettuce body and colocalize with the chloroplasts. It was proved that UCNPs could harvest the near-infrared light of sunlight and increase the electron transfer rate in the photosynthesis process, thus increasing the photosynthesis rate. The gene expression analysis showed that more than 90% of gene expression in photosynthesis was upregulated. After spraying the UCNP solution on the leaves of lettuce and placing the lettuce under sunlight for 1 week, the wet/dry weight of the leaves increased by 53.33% and 45.71%, respectively. This nanoengineering of light-harvesting UCNPs may have great potential for applications in agriculture.
