However, the inherent bioinert properties of titanium implants result in insufficient osseointegration, making it important to develop an efficient surface modification strategy to provide titanium implants with enhanced osseointegration capabilities in diabetic conditions. Here, a micro/nanostructure was constructed on titanium through acid etching and anodic oxidation, followed by an addition of a multilayered film of chitosan (CHI), gelatin (GEL) and icariin (ICA) onto the surface of micro/nanostructured titanium using a layer-by-layer self-assembly technology. The characterization results indicated that the icariin-loaded multilayered film was successfully deposited onto titanium surface and achieved a long-term sustainable release of ICA. Cell experiments showed that the icariin-loaded multilayered films modified titanium promoted osteogenesis, inhibited osteoclast generation, and reduced inflammatory reaction under diabetic conditions. This study provides an avenue for treating fractures in patients with diabetes.</div></div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142528420","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}

In particular, CPCs with controllable optical properties are promising materials for advanced photonic applications. Principally, the optical properties of CPCs, i.e., reflection wavelengths and reflection intensities, are controllable. These two characteristics are closely related to the assembled structures of CPCs, especially interplanar spacing and regularity of the assembled structures. The reflection wavelength is proportional to the interplanar spacing of the structure; thus, uniform expanding/contracting of particle-to-particle distance causes red/blue shift of reflection peaks. On the other hand, the regularity affects the reflection intensity; reversible order–disorder transitions enable tuning of the reflection peak intensities. To control the structures of CPCs, various stimuli-responsive polymers and electromagnetic interactions of colloids have been employed. This review explains the above methods and clarifies the future perspectives.</p></div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2215038224000414/pdfft?md5=1a401ae7e9b68616a27dcb098314523e&pid=1-s2.0-S2215038224000414-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142148643","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}

However, transitioning AuNPs from lab to bedside faces challenges due to the inconsistent antibacterial outcomes and the need for a consensus on the optimal AuNP features that harness their potential as antibacterial agents. This review navigates through the interplay of AuNPs' surface and their antibacterial behavior, considering their surface charge, surface potential, surface coating, surface area, morphology, and antibiotic functionalization.

Under normal conditions, BP nanosheets exhibit no adverse effects on cells and worms. However, the ability of cells and worms to resist oxidative stress is significantly impaired by BP nanosheets. Mechanism studies show that hydroxyl radical overproduction is induced by the reaction between BP nanosheets and H<sub>2</sub>O<sub>2</sub>, which may disrupt mitochondrial integrity and promote the leakage of cytochrome <em>c</em> from mitochondria into cytoplasm. Meanwhile, BP nanosheets are degraded under oxidative stress conditions, providing opportunities for BP nanosheets to interact with cytochrome <em>c</em>, thereby disrupting the cellular antioxidant defense system and ultimately producing toxicity.
