It is vital to maintain the cornea’s integrity and transparency throughout the healing process, alongside achieving exceptional biocompatibility. Unfortunately, corneal injuries often result in the excessive production of reactive oxygen species (ROS), which can significantly hinder the healing process. To meet the increasing demand for advanced biomaterials that integrate high transparency, strong adhesion, and effective ROS-scavenging properties for corneal regeneration, this study presents an innovative multifunctional composite hydrogel named GOH-S. This hydrogel is formulated using a careful sequential crosslinking strategy that combines gelatin methacrylate (GelMA), oxidised dextran (ODEX), and thiolated hyaluronic acid (HA-SH). The GOH-S hydrogel features an interconnected porous microstructure and impressive mechanical properties. Its exceptional adhesive strength allows it to securely bond to the wound site, effectively resisting blinking or tear flow and natural eye movements. In testing, GOH-S demonstrated over 85% transparency, minimising visual obstruction for patients while facilitating clinical observation and monitoring. The remarkable potential of the GOH-S hydrogel for corneal repair and regeneration is attributed to its dual functionality: efficient scavenging of harmful ROS and outstanding biocompatibility. This advancement presents a significant opportunity to enhance corneal treatment and improve patient outcomes.","PeriodicalId":12524,"journal":{"name":"Frontiers in Materials","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://public-pages-files-2025.frontiersin.org/journals/materials/articles/10.3389/fmats.2025.1698044/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While nitric oxide (NO) demonstrates dual antibacterial and immunomodulatory potential, the therapeutic application of BNN6—a near-infrared-responsive NO donor—in CVC materials requires systematic validation. This study developed a BNN6-integrated polyurethane-polydopamine (PU-PDA) composite coating for CVCs, assessing its structural stability, biosafety, antimicrobial efficacy, and immunoregulatory capacity. Methods The PU-PDA matrix was engineered to encapsulate BNN6 for controlled release of NO. Material characterization included hemocompatibility profiling (hemolysis/coagulation assays) and antibacterial validation against Gram-positive/negative strains. Immunomodulatory effects were evaluated through scratch wound healing, transwell migration, and inflammatory mediator expression assays, with intracellular NO dynamics quantified via fluorescence imaging. Results The composite coating exhibited optimal biocompatibility with negligible hemolytic activity (<2%). Bacterial proliferation was suppressed through NO-mediated metabolic disruption, while inflammatory cell motility demonstrated dose-dependent inhibition. Concurrently, upregulated intracellular NO correlated with reduced expression of pro-inflammatory cytokines (IL-6, TNF-α) and endothelial adhesion markers. Conclusion The BNN6-PU-PDA system achieves spatiotemporal NO delivery, effectively attenuating microbial colonization and host inflammatory cascades through modulation of inflammatory mediators. This dual-action mechanism positions the material as a promising strategy for infection-resistant CVC development.","PeriodicalId":12524,"journal":{"name":"Frontiers in Materials","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods SLA titanium specimens stored in air and 0.9% NaCl solution were served as controls and stored in three different concentrations of baicalin-containing saline solution were served as experimental groups to investigate the effects of the new storage methods. The specimens were examined for surface microstructure, surface element composition, surface wettability and roughness by field emission scanning electron microscopy, X-ray photoelectron spectroscopy (XPS), water contact angle measurement and laser confocal microscopy, respectively. In addition, the osteoblasts proliferation assay was used to investigate the bioactivity of the SLA titanium surfaces preserved in different conditions. Results The micron-scale crystals of different diameters were observed on surfaces stored in three different concentrations of baicalin-containing saline solution. XPS analyses revealed that the amount of titanium dioxide (TiO 2 ) decreased and the carbon (C) increased with the concentration of baicalin increasing. Compared to the control groups, specimens stored in baicalin-containing saline solution exhibited better hydrophilicity. The roughness results showed that specimens stored in 10 µM BA and 100 µM BA solutions displayed lower surface roughness. Moreover, the preservation of specimens in the 100 µM BA solution greatly enhanced the proliferation of osteoblasts.

Inspired by the concept of the whale’s skin self-repair ability and the influence of gut microbiota on the skin, this study ingeniously utilized the acidic properties of the lactic acid bacteria fermentation broth to dissolve chitosan (CS), forming a hydrogel while simultaneously incorporating the cell-free probiotic metabolites (CFPM) of Lactiplantibacillus plantarum HJ-S2 into a stable three-dimensional network structure.
