Carbon quantum dots from silymarin extraction for multi-fluorescent sensors, photocatalysis, and anticancer activity applications.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
In this work, water-soluble fluorescent carbon quantum dots were prepared by a one-stage hydrothermal method via a green synthesis route using silymarin extract from milk thistle seeds as a single precursor. Various experimental techniques were used to characterize the synthesized silymarin-based carbon quantum dots (SM-CQDs), to confirm their structure and investigate their potential applications in fluorescent sensors, photocatalysis and anticancer activity. The prepared SM-CQDs exhibited amorphous graphitic structure with a spherical shape and an average particle size of 4.6 ± 0.7 nm, as indicated by XRD, Raman, and TEM measurements. The FTIR results indicate the presence of diverse functionalities on the surface of the SM-CQDs, which were further confirmed by XPS analysis. Fluorescence characterization of the prepared SM-CQDs revealed blue emission with a fluorescence quantum yield (QY) value of 4.9%. Furthermore, the prepared dots exhibit temperature-sensitive photoluminescence (PL) behavior, which has been interestingly used to design economical, green, and highly sensitive fluorescent probes for the detection of Fe
