Synthesis and characterization of antibacterial CMC/AAc/ZnO nanocomposite superabsorbent using gamma radiation.
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
CMC/AAc/ZnO, a novel antimicrobial superabsorbent hydrogel, was prepared via the copolymerization of carboxymethyl cellulose (CMC) and acrylic acid (AAc) by incorporating zinc oxide nanoparticles through gamma radiation. The morphological and structural properties were investigated with the aid of characterization techniques such as scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) analysis. In addition, the swelling behaviour analysis displayed superior pH-responsive performance in distilled water than in saline solutions. XRD confirmed that the ZnO nanoparticles were present in a crystalline state in the polymer matrix. EDX mapping was also used to study the elemental distribution of ZnO, carbon, and oxygen in the nanocomposite. TGA provided evidence of substantial thermal stability; hence, the strength of the material could be very efficient. Besides, the highly effective antibacterial property of CMC/AAc/ZnO against Escherichia coli is confirmed through different assays, such as leaching and nonleaching tests. Unlike conventional methods, this technique avoids the need for chemical crosslinkers or initiators, as gamma radiation induces polymerization and incorporation of the nanoparticles. The resulting nanocomposite exhibits better swelling capacity, thermal stability, and antibacterial activity against Escherichia coli. Such properties make it a promising and novel candidate for biomedical and environmental applications. This research emphasizes the great possibilities of using CMC/AAc/ZnO nanocomposite superabsorbent polymers for manifold biomedical applications and opens up new pathways in the growth of eco-friendly antibacterial material.
