Glutathione and pH serial responsive functional mesoporous silica nanoparticles for drug delivery

In this work, a novel glutathione and pH serial dual-responsive drug delivery system has been developed, which was constructed with chitosan (CS), carbon dots (CDs) and hyaluronic acid (HA) modified the mesoporous silica nanoparticles (MSNs). The system showed excellent drug loading efficiency, controlled release and targeted delivery. In addition, the platform (MSN-CS@HA-CDs) exhibited fluorescence imaging property. The prepared drug delivery system appeared to be a promising cancer treatment platform.
