Current biomaterials are designed to promote M2 macrophage polarization by manipulating various physical properties. However, this approach lacks precision in controlling the initiation of immunomodulation, potentially leading to premature immune suppression. In this study, the photothermal effect of Ti3C2Tx MXene nanosheets under near-infrared (NIR) irradiation was employed to achieve remote regulation of macrophage M2 polarization. Ti3C2Tx exhibited excellent photothermal properties and biocompatibility. The mild thermal stimulation produced by photothermal conversion of Ti3C2Tx under NIR irradiation promoted macrophage M2 polarization in vitro. Subsequently, these photothermal-polarized macrophages increased the secretion of IL-10 and facilitated the osteogenic differentiation of BMSCs. The synergistic application of Ti3C2Tx MXene nanosheets and NIR presents an innovative strategy for remotely modulating macrophage polarization in a temporally controlled manner, thereby paving the way for the development of advanced osteoimmunomodulatory biomaterials.</div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":null,"pages":null},"PeriodicalIF":4.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their biocompatibility remains a crucial concern. Here, we investigated the cytotoxicity of hexagonal BN (h-BN) nanodots (BNNDs) on HUVEC cells, assessing their effects on viability, morphology, proliferation, cell cycle, genes, and protein expression. BNNDs had limited impact on HUVECs viability, even at high concentrations (200 μg/mL, 48 h). Yet, they hindered cell proliferation and caused cell cycle arrest in the S phase in a dose−/time-dependent manner. Cytotoxicity primarily resulted from disturbances in cell proliferation and DNA replication-related genes (e.g., GADD45A) and proteins (e.g., GADD45A). BNNDs also induced oxidative stress, enhancing cytotoxic effects. Therefore, cautious evaluation of long-term cytotoxicity is crucial before employing BNNDs in biological systems. Additionally, certain dye-based cytotoxicity assessment methods may not accurately reflect the cytotoxicity of BNNDs. Understanding these new cytotoxic mechanisms can aid in designing safer BN-based nano-medicines/devices.</div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":null,"pages":null},"PeriodicalIF":4.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bottom PDMS layer for support can provide excellent mechanical properties.
