Abstract

Mesoporous silica nanoparticles (MSNs) with closed pores have significant potential for applications such as lowdielectric-constant materials and bio-imaging owing to their controlled accessibility. In this study, we successfully prepared MSNs with closed pores by a simple hydrothermal treatment in ethanol. The mesostructure changed from open to closed mesopores through hydrothermal treatment. This simple method enabled the preparation of closed pores with encapsulated guest species.
