Photothermal-responsive MXene/curcumin-copper composite hydrogel with antioxidant, immunoregulatory, and angiogenic functions for diabetic wound healing.
Article in Journal of nanobiotechnology, 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
Diabetic wounds are a critical clinical challenge due to chronic inflammation, impaired tissue regeneration, and bacterial infection. The absence of multifunctional therapeutic systems that can address these pathological barriers simultaneously is a major obstacle in managing diabetic wounds. In this study, we developed a versatile photothermal-responsive hydrogel (HPCT) by incorporating Ti3C2 MXene nanosheets and Cur-Cu nanoparticles (NPs) into a dual-network polymer matrix. This hydrogel exhibits robust physicochemical stability, efficient photothermal conversion, and on-demand release properties. Due to the synergistic effects of its components, HPCT effectively scavenges ROS/RNS, reprograms macrophages, and promotes fibroblast and endothelial proliferation and migration. Additionally, it exhibits potent antibacterial activity. Transcriptomic analysis reveals that the bioactive material activates the PI3K-AKT and Wnt signaling pathways, providing a mechanistic basis for its regenerative potential. In vivo, HPCT significantly accelerates wound closure in diabetic mice by reducing inflammation and oxidative stress, enhancing angiogenesis, and improving collagen deposition while maintaining good biocompatibility. Overall, this multifunctional hydrogel is a promising therapeutic strategy for treating diabetic and other chronic wounds.
