Current dressings for severe burns present significant challenges and are inadequate in effectively managing early burn wounds. To address the above challenges, a deoxyribonucleic acid-functionalized collagen dressing with aligned channels and interconnected porous structure (DNA-Cryo-ACol) was developed. The DNA-Cryo-ACol dressing demonstrated superior exudate drainage abilities: (i) draining excess exudate at a rate 50 times faster than commercial dressings; (ii) doubling the maximum exudate absorption capacity compared to commercial dressings; and (iii) preventing exudate maceration through evident capillary action. Furthermore, DNA-Cryo-ACol dressings exhibited the immunomodulatory property to regulate immune responses mediated by CD4 + T cells. Results indicated that the interaction between DNA-Cryo-ACol dressing and CD4 + T cells stimulated the production of scar-inhibiting cytokines while reducing the expression of α-smooth muscle actin. By effectively managing exudate drainage and immune response, DNA-Cryo-ACol dressings significantly promoted tissue regeneration in healed burn wounds, resulting in a sevenfold increase in hair regrowth and recovery of collagen components to levels comparable to unwounded skin. The findings from this study laid the groundwork for the development of smart materials aimed at early burn wound management to inhibit scarring.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 2","pages":""},"PeriodicalIF":23.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01295-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current treatment options, including antifungal medications and denture disinfectants, are often limited by adverse effects and reduced efficacy. To address these challenges, this study aims to develop a novel dendritic polymer coating for dentures, which incorporates hydrophobic quaternary ammonium salts (QAS), hydrophilic catechol functional groups, and aggregation-induced emission (AIE) fluorophores. QAS, known for their broad-spectrum antimicrobial activity, are integrated into the coating to enhance the adhesion and antimicrobial properties. Catechol functional groups, rich in the dendritic polymer structure, contribute to improved stability and adhesion of the coating, which is crucial for long-term efficacy in the dynamic oral environment. Additionally, AIE fluorophores enable real-time monitoring of coating integrity, overcoming limitations of traditional fluorescent dyes. The study focuses on optimizing coating construction techniques, with an emphasis on enhancing adhesion, antimicrobial functionality, and real-time monitoring capabilities. Investigations into the antimicrobial mechanism of the coating aim to elucidate its potential in combating DS and offering solutions for therapeutic dentures.

Despite numerous studies on multifunctional EMI shielding fabrics, research on developing such materials using resource-efficient and cost-effective strategies is scarce. The present study introduces a pioneering approach to crafting simulation-engineered carbonized cotton-based EMI shielding fabrics with diverse multifunctionality by leveraging the strategy of electromagnetic (EM) simulations and ferrite decoration. The exceptional conductivity of carbonized cotton stemming from plasmonic electronic states, together with ferrite integration, plays a significant role in enhancing the EMI shielding ability of the fabrics. Ferrite integration is found to be instrumental in reducing the reflection and enhancing the absorption of EM radiations. EM simulations based on a double-layer fabric model demonstrated ~ 60 dB shielding effectiveness for a fabric with 0.75mm thickness, which is further verified via experimental testing. A comprehensive analysis of the EM parameters of the shielding fabric unveiled the existence of unique high-frequency negative permittivity, the high dielectric loss of the order of 10, multiple dielectric-magnetic relaxations, and high attenuation constant in the order of 10<sup>3</sup>, which significantly contributed to the effective absorption of EM waves. Furthermore, the fabricated EMI shielding fabrics exhibit a plethora of desirable traits, including superior Joule heating performance, photo-thermal capabilities, efficient thermal management, and remarkable hydrophobicity.
