Soft tissue is characterized by high dynamic strain and a complex immune microenvironment, imposing stringent requirements on the mechanical properties, biocompatibility, and surface characteristics of implanted materials. Therefore, compared to the success in implant/hard tissue integration, implant/soft tissue integration remains challenging, and failure to form a stable implant/soft tissue interface is often observed, leading to inflammation, tissue rejection, or even implant failure. To address this issue, we developed acrylic resin/bioactive glass composites. It was found that compositing bioactive glass significantly improved the soft tissue integration of the acrylic resin and effectively reduced its inflammatory response. A demonstration of the obtained composite in subgingival dentin defect restoration showed improved gingival covering and biological seal, highlighting its potential applications in cases where soft tissue integration is essential.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":"6100-6108"},"PeriodicalIF":4.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these critical barriers, we developed a methacrylated silk fibroin (Sil-MA) bioink that combines high biocompatibility with enhanced printability. By systematically optimizing material formulation, printing parameters and MN geometry, we successfully fabricated DLP-printed Sil-MA MNs with precise architecture control and superior mechanical performance. These MNs demonstrated no cytotoxicity and enabled efficient transdermal delivery of three distinct dermatological therapeutics. Comprehensive in vitro and in vivo assessments indicated that the DLP-printed Sil-MA MNs also acted as mechanical stimulators, significantly promoting epidermal keratinocyte proliferation. This engineered platform offers a versatile strategy for developing multifunctional MN systems for therapeutic delivery and tissue engineering applications.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":"6025-6039"},"PeriodicalIF":4.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photothermal therapy (PTT) has been a high-potential method in antibacterial therapy on account of its noninvasion and avoiding bacterial resistance. However, high temperatures and nonselectivity related to PTT would cause serious damage to the surrounding healthy tissue. Herein, a surface-adaptive gold-based nanoplatform (AuNPs@GalNAc/DMMA-Cys) by conjugating N-acetylgalactosaminoside (GalNAc) and maleimidized cysteine (DMMA-Cys) on gold nanoparticles for low-temperature photothermal antibacterial therapy was proposed. The AuNPs@GalNAc/DMMA-Cys was characterized by the pH-activated photothermal effect on account of the translation from negative property to zwitterionic structure of DMMA-Cys and high adhesion toward UPEC originating from the recognition of GalNAc to FmlH protein. It can kill UPEC under low photothermal temperature but perform poorly against <i>S. aureus</i>. This approach may develop a promising tool for low-temperature photothermal antibacterial treatment.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":"5680-5688"},"PeriodicalIF":4.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
