Periodontitis is a chronic inflammatory disease caused by dental plaque, which leads to tooth loosening and shifting or even tooth loss. Current treatments, including mechanical debridement and antibiotics, often fail to eradicate recalcitrant biofilms and mitigate excessive inflammation. Moreover, these interventions can disrupt the oral microbiome, potentially compromising long‐term treatment outcomes. To address these limitations, an injectable nanoenzyme hydrogel composed of a dopamine (DA)‐modified hyaluronic acid (HA) scaffold and a graphdiyne‐iron (GDY‐Fe) complex, named GDY‐Fe@HA‐DA, exhibits excellent tissue adhesion, self‐healing, antibacterial properties, and biocompatibility. Under near‐infrared laser irradiation, GDY‐Fe@HA‐DA effectively eradicates a variety of pathogens, including Escherichia coli, Staphylococcus aureus, and Porphyromonas gingivalis, through a synergistic combination of chemodynamical and photothermal therapies. The hydrogel's efficacy is further validated in both bacterial‐infected skin wounds and rat periodontitis models. It effectively alleviates the inflammatory environment and promotes wound healing and periodontal tissue recovery. This findings highlight the potential of GDY‐Fe@HA‐DA as a promising therapeutic material for periodontitis and other tissue injuries.

Among the various fire‐retardants (FRs) known, phosphorus is vital to the development of effective FRs due to its flexibility. Additionally, the additives and combinations of phosphorus with various multicomponent moieties (e. g. P−Si, P−P, P−B, etc.) can serve the purpose in different phases to improve flame retardance properties. With an increased cognizance of recyclable, eco‐friendly, and bio‐based materials, phosphine oxide‐based materials/coatings can fulfill the criteria for flawless and future FRs. In this regard, the present review highlights the most promising organophosphorus‐based compositions as non‐intrusive FRs. The classification, synthetic methods, related mechanisms, and high‐end FR applications of various recently developed organophosphorus‐based molecules and materials are demonstrated. Among various organophosphorus compounds, the phosphorus‐based polyurethane materials display remarkable FR properties and non‐toxic behavior. Notably, the flame retardance of the epoxy resins is enhanced significantly with the presence of more P=O bonds and amino groups. The limitations and advantages of organophosphorus‐based materials are compared with the traditional FRs. Also, the challenges persisting in improving current flame‐retardant materials need to be addressed. However, the success of these materials and treatment methods strongly depends on the ability to impart desired functionality, durability, and scalability without compromising environmental problems.
