Fig. 6From: A novel pH- and glutathione-responsive drug delivery system based on in situ growth of MOF199 on mesoporous organic silica nanoparticles targeting the hepatocellular carcinoma nicheIn vivo distribution of the nanocomposites. Mice were injected with PBS (A), FITC (B), D/S@MM (C), and D/S@SPMM (D) via tail vein. In vivo imaging was performed on an in vivo imaging system at 1, 4, 8, 12, and 24Â h post-injectionBack to article page
