Synthesis and characterization of the DMSN antigen carrier. (A) Schematic representation of the study design. The DMSN served as a nanocarrier for delivering both the RBD and conserved T-cell epitope peptides of SARS-CoV-2. (B) Synthetic routes of the DMSN. CTAB and NaSal were utilized as the structure-directing agent, with TEOS as the source of silica, and TEA catalyzed the reaction. (C) The DMSN structure was examined by TEM. Scale bars, 200Â nm. (D) Hydrodynamic diameter of the DMSN was determined through DLS measurements
