Hollow silica nanoparticles

In this study, we used a new class of fluorinated surfactant as a soft template for the preparation of the hollow silica nanoparticles. The size of the hollow silica nanoparticles was enlarged by incorporating a variety of swelling agents (perfluorodecalin, perfluorotributylamine, perfluorooctane, and perfluorooctyl bromide) into the cores of the micelles of the fluorinated surfactant. However, once we used the perfluorinated acids (perfluorooctadecanoic acid and perfluorodecanoic acid) as swelling agents, the structure of silica nanoparticles is solid without the formation of hollow voids.

Mesoporous silica nanoparticles (MSNs) have attracted significant attention from researchers thanks to their high surface area and pore volume, which can increase drug loading capacity. Moreover, MSNs, with their biocompatibility and ease of surface functionalization, are seen as potential drug delivery system. However, the loading of drug into MSNs system still needs further improvement. In this study, hollow mesoporous silica nanoparticles (HMSNs) were fabricated in order to increase the drug loading capacity of nanosilica materials.
