Green synthesis of quercetin-mediated ZnS quantum dots and their photocatalytic, antimicrobial, and cytotoxic performances.
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 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
In this study, ZnS quantum dots (QDs) were synthesized via a green, simple, cost-effective, and sustainable method using quercetin as a reducing and stabilizing agent. Successful synthesis was confirmed by UV-vis and Photoluminescence (PL) spectroscopy, revealing characteristic optical properties. Structural and morphological features were analyzed by ATR-FTIR, XRD, SEM-EDX, and TEM, showing crystallinity, surface functionalities, and nanostructure, with TEM confirming particle sizes ≤ 10 nm. The anti-biofilm activity was tested against E. coli ATCC 35218 and P. aeruginosa ATCC 27853, showing significant inhibition, especially against E. coli. Antifungal activity against C. albicans ATCC 10239 (agar disk diffusion) revealed larger inhibition zone (22 mm) than the reference antibiotic (20 mm). The MTT assay revealed high biocompatibility, with L929 fibroblast cell viability remaining above 75% across all test conditions. Under 24 h of UV irradiation, the photocatalytic degradation efficiency reached 85% for Brilliant Green (BG) and approximately 70% for Methylene Blue (MB). Photoluminescence stability was examined between 0-40 °C, showing good thermal stability with minimal structural degradation. These results suggest ZnS QDs possess promising antimicrobial, antifungal, photocatalytic, and biocompatible properties, supporting their potential in biomedical and environmental applications.
