Dual-responsive targeted hollow mesoporous silica nanoparticles for cancer photodynamic therapy and chemotherapy J. Macromol. Sci. A (IF 2.5) Pub Date : 2023-05-26 Yuqi Chen, Xuelian Wang, Zhuhang Lu, Cong Chang, Yueli Zhang, Bo Lu
Abstract Surface modification of hollow mesoporous silica nanoparticles (HMSNs) with unique advantages are highly promising for drug delivery and have emerged for effective cancer treatment. In this study, functionalized nanoparticles for targeting and dual-responsive release of loaded doxorubicin hydrochloride (DOX·HCL) and indocyanine green (ICG) (labeled as ID@HCH). In addition, chitosan (CS) was
