Benefit from the unique surface properties of skin, the skin-based nanofiber membrane demonstrated improved roughness and enhanced air permeability.

The cryogels feature a porous and loose structure that facilitates water and gas exchange, as well as the absorption of wound exudate. Additionally, ATP-2Na-coordinated cryogel (G-ATP) stimulates cellular proliferation and migration, while exhibiting anti-inflammatory properties, thus creating an optimal environment for wound repair. In vivo experiments in a full-thickness wound model showed accelerated healing with the G-ATP group, which outperformed control groups in wound contraction and collagen deposition.

Although bone tissue has a certain capacity for self-repair, artificial substitute materials of bone are still required to facilitate the repair, especially for large-scale bone defects. At present, tissue engineering-related materials that mimic the structure, mechanical properties, and biological characteristics of natural bone have been widely used for addressing bone defects and promoting in situ bone regeneration. Hydrogels that emulate the properties of the extracellular matrix are prevalent materials in bone tissue engineering, with a particular emphasis on those crosslinked through HRP-mediated, which have garnered considerable interest due to their high efficiency of preparation, mild reaction conditions, controllable properties, and excellent biocompatibility. However, the suboptimal osteogenic capability inherent in HRP-mediated crosslinked hydrogels necessitates the integration of additional osteogenic activity materials, such as biological calcium phosphates, biomimetic scaffolds, growth factors, synthetic peptides, and nanomaterials, to bolster the hydrogel scaffolds' osteogenic potential. This manuscript provides a concise overview of the standard methodologies for crafting injectable hydrogels, highlighting the HRP catalytic reaction mechanism, and strategies for modulating hydrogel attributes. Furthermore, this paper delves into the recent advancements in HRP-mediated crosslinked hydrogel scaffolds, highlighting their role in bone defect repair within the realm of bone tissue engineering. These insights establish a robust foundation for the innovation, development, and clinical application of bone tissue substitutes that prioritize biosafety.</div></div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":"66 ","pages":"Article 100828"},"PeriodicalIF":4.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143578358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ongoing efforts to reduce these side effects are hampered by the generally poor understanding of its mode of action and behavior in solution. A key question that has been debated is whether colistin self-assembles into micelles or remains as unimers in solution.
