Luminescent heparin-functionalized carbon dots with potential applications in nanoparticle-protein interactions and cell imaging.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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, we report the synthesis and comprehensive characterization of heparin-capped carbon dots (Hep-C-dots) prepared using D-glucose as a carbon precursor and heparin, a negatively charged polysaccharide belonging to the glycosaminoglycan family, as a capping and stabilizing agent. The obtained Hep-C-dots exhibited a uniform nanoscale size distribution with an average diameter of 2.5 ± 0.5 nm and a high negative surface charge (- 36.8 mV). Full characterization of as-synthesized Hep-C-dots has been done by several state-of-the-art analytical techniques, such as transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-visible spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and zeta potential analysis. The interactions between Hep-C-dots and key human proteins, namely human methemoglobin (HB) and human serum albumin (HSA), were investigated via fluorescence spectroscopy, demonstrating significant binding affinities with K
