Enhanced urease inhibitory activity of quercetin via conjugation with silver nanoparticles: synthesis, characterization, and DFT study.
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 4 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
Urease plays a crucial role in the survival and colonization of Helicobacter pylori (H. pylori). Consequently, urease inhibitors are important in managing various diseases associated with H. pylori infection. Given the widespread use of silver nanoparticles (AgNPs) as antibacterial agents and quercetin's known urease inhibitory properties, we sought to develop a potent urease inhibitor by conjugating quercetin onto AgNPs. In fact, this study aimed to enhance the urease inhibitory activity of quercetin through its conjugation with AgNPs. Quercetin-loaded silver nanoparticles (Ag@QNPs) were successfully synthesized using the Frens method and characterized using various techniques, including UV-Vis spectroscopy, FT-IR spectroscopy, XRD analysis, DLS, and TEM. The urease inhibitory activity of Ag@QNPs was significantly higher (approximately 250 times) than that of pure quercetin, demonstrating a synergistic effect. In contrast, AgNPs alone exhibited minimal inhibitory activity against urease. Density functional theory (DFT) calculations revealed a favorable interaction energy between quercetin and the silver surface. These findings suggest the potential of Ag@QNPs as promising nanomaterials for applications in urease-related diseases.
