“…The preparation and functionalization of CDs-gl&al were based on CDs-gl. 27 To investigate the changes in the CDs before and after functionalization, we first observed the size and lattice morphology of the CDs using high-resolution transmission electron microscopy (TEM). It could be observed from Figure 2a,b that the particles of CDs-gl and CDs-gl&al were uniformly dispersed and microspherical, with average diameters of around 2.08 nm for CDs-gl and 1.61 nm for CDs-gl&al.…”

“…In the preparation of CDs, the selection of carbon sources is crucial, which is related to the performance, sustainability, and safety of CDs. , Biomass, as an environmentally friendly material, is an excellent precursor for preparing CDs, and using it to produce CDs can solve the problems of safety and sustainability. , In our previous work, we prepared a bioactive CD material using biomass and furthermore demonstrated that compounds with amino groups could be well involved in the preparation of CDs from biomass and improve the properties of biomass CDs. Therefore, in solving the problem of CD synthesis, biomass materials containing bioactive components can be selected, and CDs can be modified by introducing molecules with specific structures to optimize their properties.…”

The application of carbon dot (CD) nanomaterials in the agricultural field has shown unique advantages, among which preparing an efficient CD material is the key to its popularization and applications. In this work, a biomass CD material (CDs-gl&al) that can be used for efficient improvement of plant photosynthesis was prepared. Compared with the control, the electron transport rate and actual photosynthetic efficiency of lettuce leaves treated with CDs-gl&al increased by 43.5 and 40.1%, respectively, and the contents of chlorophyll a and chlorophyll b increased by 23.9 and 21.0%, respectively, significantly enhancing the photosynthetic capacity of lettuce. After being absorbed by leaves, CDs-gl&al was mainly transported to other parts through leaf veins. In the assay of superoxide dismutase (SOD) and malondialdehyde (MDA) levels, CDs-gl&al was able to increase the SOD content and decrease the MDA level in the leaves, thus enhancing the lettuce resistance and improving the growth status of lettuce. In experiments with fruit trees, CDs-gl&al had a similar effect in promoting photosynthesis in fruit tree leaves. The coculture experiments with various cells such as mouse small intestine epithelial cells proved that this material had good biosafety. CDs-gl&al would help to further promote the application of CDs in the agricultural field.
