Dynamic covalent chemistry provides a compelling foundation for such materials by combining covalent stability with reversible bond exchange, enabling adaptability, self-healing, and stimulus-responsive behavior. Dynamic covalent biomaterials have therefore emerged as promising platforms for tissue scaffolds, wound healing, and controlled delivery applications. Although many existing systems respond to a single stimulus, such as pH, redox conditions, or enzymatic activity, biological environments are inherently multiresponsive, integrating mechanical, chemical, and biochemical cues simultaneously. As a result, single-stimulus dynamic materials often fail to achieve predictable performance in vivo. This review focuses on chemical strategies for engineering multistimuli responsive dynamic covalent materials that more closely reflect the complexity of native regenerative processes. We discuss key reversible covalent motifs, their thermodynamic and kinetic characteristics, and how these can be combined through orthogonal chemistries, multicomponent networks, and hierarchical architectures to achieve tunable mechanics, stress relaxation, degradation, and biofunctionality. Finally, we outline current challenges and opportunities, emphasizing the need for expanded biocompatible chemistries and rational design principles to advance multistimuli responsive dynamic covalent materials toward translational regenerative medicine.</p>","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":"15 38","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adhm.71721","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148987194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While modulating immunometabolism is a promising therapeutic avenue, achieving subcellular-targeted delivery of bioactive molecules remains a formidable challenge. Here, we report a mitochondria-targeted nanozyme designed to concurrently scavenge mtROS and reprogram DC metabolism for effective anti-inflammatory therapy in periodontitis. This system is constructed based on Prussian blue nanoparticles (PB NPs) loaded with manganese carbonyl, a high oxidative stress-responsive carbon monoxide (CO) donor, and further modified with triphenylphosphine for mitochondrial targeting. This nanozyme efficiently accumulates in the mitochondria of activated DCs, where it efficiently scavenges mtROS and concurrently delivers controlled CO release, synergistically modulating DC function. Metabolomics analysis reveals that CO suppresses DC maturation by reprogramming cellular metabolism, including inhibiting the tricarboxylic acid cycle, modulating glycolysis, and disrupting fatty acid synthesis. Consequently, the synergistic action of PB NPs and CO effectively reverses the pro-inflammatory phenotype of DCs, reshapes the immune microenvironment, and ultimately alleviates periodontal inflammation in vivo.
