Preparation, morphology, and structure characterization, composition, and cytotoxicity of mesoporous silica particles with controlled mesopore sizes. A) Schematic illustration of the overall preparation procedure for mesoporous silica particles with controlled mesoporous sizes. B) The nitrogen adsorption–desorption isotherm of the prepared mesoporous silica detected by BET. C) Particle size distribution curve of the prepared mesoporous silica detected by Nano Sizer and Zeta‐potential Tester. D) Morphology and structure characterization of the prepared mesoporous silica detected by SEM. E) Zeta potential distribution curve of the prepared mesoporous silica. F) FTIR and XRD analysis of the prepared mesoporous silica. G) TG‐DSC of the prepared mesoporous silica. H) Cytotoxicity test of the prepared mesoporous silica using CCK‐8. Data are presented as means ± s.d.; n = 5; *p < 0.05, **p < 0.01, ***p < 0.001 by two‐way ANOVA with Tukey's post hoc test.
