“…It was found that all three types of CDs triggered the antioxidant defense systems (SOD, POD, CAT) [ 82 ]. The available literature has recently been reviewed by [ 83 ]. Furthermore, in a comparative study, the most significant promoting effect of functional CDs (FCNs), possessing the largest number of functional groups and a small size, on the growth of Arabidopsis thaliana seedlings, was observed.…”

Due to recent active research, a large amount of data has been accumulated regarding the effects of different nanomaterials (mainly metal oxide nanoparticles, carbon nanotubes, chitosan nanoparticles) on different plant species. Most studies have focused on seed germination and early seedling development, presumably due to the simplicity of these experimental systems. Depending mostly on size and concentration, nanomaterials can exert both positive and negative effects on germination and seedling development during normal and stress conditions, thus some research has evaluated the phytotoxic effects of nanomaterials and the physiological and molecular processes behind them, while other works have highlighted the favorable seed priming effects. This review aims to systematize and discuss research data regarding the effect of nanomaterials on germination and seedling growth in order to provide state-of-the-art knowledge about this fast developing research area.

“…Composite materials based on CDs have been often reported to have phosphorescence observed at room temperature, which is a useful property for data encryption [ 20 , 21 , 22 ]. CDs even found some applications in agriculture, where they were used to improve plant growth and production [ 23 ]. Due to their strong absorption [ 24 ], CDs were used as sensitizers in solar cells [ 25 , 26 ].…”

Carbon dots (CDs) are an attractive class of nanomaterials due to the ease of their synthesis, biocompatibility, and superior optical properties. The electronic structure of CDs and hence their optical transitions can be controlled and tuned over a wide spectral range via the choice of precursors, adjustment of the synthetic conditions, and post-synthetic treatment. We summarize recent progress in the synthesis of CDs emitting in different colors in terms of morphology and optical properties of the resulting nanoparticles, with a focus on the synthetic approaches allowing to shift their emission to longer wavelengths. We further consider formation of CD-based composite materials, and review approaches used to prevent aggregation and self-quenching of their emission. We then provide examples of applications of CDs in optoelectronic devices, such as solar cells and light-emitting diodes (LEDs) with a focus on white LEDs.

“…There have been some attempts to apply these nanoparticles in plants [ 68 ], but they are still at an early stage, and these nanoparticles have not been used for single-molecule imaging. The absorption, accumulation, and imaging of UCNPs [ 69 , 70 ], PDots [ 71 ], FNDs [ 72 ], and CDots [ 73 ] in plants have been studied. Similar to QDs, their specific labeling is also a major problem.…”

Single-molecule imaging is emerging as a revolutionary approach to studying fundamental questions in plants. However, compared with its use in animals, the application of single-molecule imaging in plants is still underexplored. Here, we review the applications, advantages, and challenges of single-molecule fluorescence imaging in plant systems from the perspective of methodology. Firstly, we provide a general overview of single-molecule imaging methods and their principles. Next, we summarize the unprecedented quantitative details that can be obtained using single-molecule techniques compared to bulk assays. Finally, we discuss the main problems encountered at this stage and provide possible solutions.
