DNA delivery into plant tissues using carbon dots made from citric acid and β-alanine.
Article in Frontiers in chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Agriculture and food security face significant challenges due to population growth, climate change, and biotic and abiotic stresses. Enhancing crop productivity and quality through biotechnology is crucial in addressing these challenges. Genome engineering techniques, including gene cassette delivery into plant cells, aim to meet these demands. However, conventional biomolecule delivery methods have limitations such as poor efficacy, low regeneration capability, and potential cell damage. Nanoparticles, known for their success in drug delivery in animals, hold promise as DNA nanocarriers in plant sciences. This study explores the efficacy of carbon dots (CDs), synthesized rapidly and cost-effectively from citric acid monohydrate and β-alanine using a microwave-assisted method, as carriers for plasmid DNA delivery into plant tissues. The detailed characterization of carbon dots, evaluation of their binding ability with plasmid DNA, and phytotoxicity assessments were systematically conducted. The delivery and expression of plasmid DNA were successfully demonstrated in canola leaves via needleless syringe infiltration and in soybean root cells and protoplasts through passive diffusion. Additionally, the particle bombardment method facilitated the efficient delivery of plasmid DNA of varying sizes (4 kb, 11 kb, and 17 kb) into onion epidermal cells, as well as the successful delivery of plasmid DNA containing the GUS reporter gene into soybean embryos, using carbon dots as a binding agent between plasmid DNA and tungsten microcarrier. To our knowledge, this is the first study to report the use of carbon dots as a substitute for spermidine in such applications. Overall, our research presents a rapidly synthesized, cost-effective platform for efficient plasmid DNA delivery, establishing a foundation for using carbon dots as carriers for CRISPR and RNAi constructs in gene knockout and knockdown applications in plant tissues, with a comparison of their transformation efficiency against traditional delivery techniques.
