Novel scheme for rapid synthesis of hollow mesoporous silica nanoparticles (HMSNs) and their application as an efficient delivery carrier for oral bioavailability improvement of poorly water-soluble BCS type II drugs.
TL;DR: In vitro studies conducted in the present work showed that compared with pure CAR and CAR loaded MSNs (CAR-MSNs) synthesized by Stober method, the drug-loaded HMSNs ( CAR-HMSNs), developed using a simple, quick, and inexpensive method, exhibit sustained drug release performance.
