Sustainable Doped Carbon Dots as Antioxidant and Nanocarrier for Therapeutic Cargos.
Article in Journal of fluorescence, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Aside from their fluorescence sensing capabilities, carbon dots doped with heteroatoms show tremendous promise as nanocarriers for medicinal compounds and as antioxidants. We present a method for producing carbon dots from chitosan and lemon extract (CLCDs) using a one-step hydrothermal coupling synthesis. The as-synthesized CLCDs exhibited remarkable colloidal stability, antioxidant behavior, cytocompatibility, and nanocarrier for drug molecules. The nanoparticles was analyzed using advanced techniques such as Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), fluorescence spectroscopy, electron paramagnetic resonance (EPR) spectroscopy, and transmission electron microscopy (TEM) to determine the precise composition of their surface. In order to evaluate the drug transport properties of CLCDs, their surfaces were further modified with anticancer drug compounds. The drug release behavior was studied against physiologically simulated fluids and at different pH environments showing better delayed response in acidic condition. The plausible mechanistic pathways have been confirmed after fitting the results into Higuchi, Weibull and Korsmeyer-Peppas models. The goodness of fit was more than 95% for the Korsmeyer-Peppas model, with the release mechanism supported by anomalous transport. Moreover, the radical scavenging activity of CLCDs was also confirmed at low levels (1 mg/mL) which could be inferred > 85% efficacy against mostly employed testing agents (DPPH, ABTS, and hydroxyl radicals). Thus, the prepared CLCDs could be used as suitable nanovector in payload delivery with prominent antioxidant activity and low toxicity against living cell lines.
