A facile two step synthesis of novel chrysanthemum-like mesoporous silica nanoparticles for controlled pyrene release

Abstract

Chrysanthemum-like mesoporous silica nanoparticles (MSNs) with large surface areas were successfully synthesized in the presence of ethyl ether by a facile two-step method under mild conditions. Pyrene was chosen to evaluate their drug loading and controlled release properties. The results showed that prepared MSNs exhibited excellent release rate.
