In order to achieve a controlled release drug delivery system (DDS) for cancer therapy, a pH\nand redox dual-responsive mesoporous silica nanoparticles (MSN)-sulfur (S)-S- chitosan (CS) DDS was\nprepared via an amide reaction of dithiodipropionic acid with amino groups on the surface of MSN\nand amino groups on the surface of CS. Using salicylic acid (SA) as a model drug, SA..................
