| Abstract |
When the mesoporous silica nanoparticles are synthesized through self-assembly process, the cationic surfactant’s role is paramountly important. Cetyltrimethylammonium bromide (CTAB) or cetylpyridinium bromide (CTPB) are well-known ammonium-based surfactants frequently used for mesoporous silicas. Meanwhile, there is a cationic surfactant that has a fluorocarbon chain like FC-4, and the chain is neither hydrophilic nor hydrophobic and is insoluble in water. In this study, mesoporous silica vesicles (MSVs) were successfully synthesized by using a binary mixed template system, CTPB and FC-4. In addition, the mesopore expansion and template-removal were simultaneously achieved by Ca ion-etching method using the as-prepared MSVs. The Ca ion-etching process effectively generated large surface holes through partial collapse of several mesopores. The Ca ion-etched MSV (Ca-MSV) showed better abilities encapsulating proteins compared to the calcined MSV with smaller mesopores. The Ca-MSV was especially good at adsorbing large size proteins such as hemoglobin, ovalbumin, and bovine serum albumin. |
