In this study, the surface of mesoporous silica nanoparticles (MSN) was functionalized with the phosphonate group (-PO3) to facilitate the adsorption and targeted delivery of curcumin to cancer cells, concurrently significantly enhancing the stability of the nanomaterial. Methodologies including scanning electron microscopy, Fourier transform infrared spectroscopy, N2 adsorption isotherms, and thermal gravimetric analysis were systematically employed to characterize the features of the nanomaterials. The assessment of curcumin loading efficiency within both MSN and phosphonate-functionalized MSN (MSN-PO3) was conducted, predicated upon interactions with the loading solvent and the material's stability. Notably, stability assays revealed that unmodified particles exhibited agglomeration within a 96-h period, while their modified counterparts maintained their structural integrity. Moreover, discerning outcomes from in vitro cytotoxicity assays unveiled the potent efficacy of curcumin-loaded materials against colorectal cancer cells (C-26), with minimal impact on fibroblast cells (L929).

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.

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.
