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.

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.
