GSH stimulated the drug release from DOX-loaded CET-capped MP-SiO2 NP.

(a) Absorbance spectra corresponding to the released DOX from CET-capped MP-SiO2 NP treated with different concentrations of GSH for 1 hr. (b) Time-dependent absorbance changes observed upon the DOX release from CET-capped MP-SiO2 NP without and with 1 mM GSH. Bars represent mean ± SEM (n = 3).
