Traditional methods for cartilage treatment often involve complex surgical procedures with limited efficacy. Alternatively, implantable drug-loaded scaffolds are an increasingly attractive cartilage treatment option. To address the challenges of structural and functional compatibility between scaffolds and native cartilage, as well as issues related to drug loading, we design a novel cartilage scaffold with a four-region hollow porous fiber network structure. Using an extrusion-based 3D printing platform, a biphasic silicone ink composed primarily of liquid-phase silicone and solid particles was employed to construct the hollow porous fiber network. Mechanical compression tests demonstrate that the cartilage scaffold has mechanical characteristics similar to those of native cartilage tissue, and ultraviolet spectrophotometry measurements confirm its ability to control drug release. These results showcase the feasibility and effectiveness of the proposed cartilage substitute structure.","PeriodicalId":17508,"journal":{"name":"Journal of Zhejiang University-SCIENCE A","volume":"26 11","pages":"1070-1082"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This produced chemically bonded interacting composite photocatalysts of FA-SiO2 and graphitic-phase carbon nitride (g-C3N4). Compared with the spherical silicon dioxide prepared using tetraethyl orthosilicate (TEOS-SiO2), the mesoporous structure of FA-SiO2 allowed DCDA to react in a smaller space, which facilitated the transformation of DCDA to melamine by the thermal degradation kinetics of FA-SiO2/DCDA. This ultimately boosted the formation of an N-atom-removed triazine ring structure and a multistage structure combining lumps and rods in the composite photocatalysts of g-C3N4 and FA-SiO2, which led to a higher visible-light utilization efficiency, a suitable valence-band position, and the photocatalytic activity for methylene blue reaching 3.56 times that of g-C3N4. The findings indicate that mesoporous FA-SiO2 has the potential to improve the structural and photocatalytic properties of g-C3N4-based materials.","PeriodicalId":17508,"journal":{"name":"Journal of Zhejiang University-SCIENCE A","volume":"26 7","pages":"694-706"},"PeriodicalIF":0.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
