(A) Cytotoxicity of micelles against C6 cells after 48 ​h of incubation; (B) cytotoxicity of micelles against Saos-2 ​cells ​after 48 ​h of incubation. (C) Antitumour activity of DOX-loaded SS-PU-SS-PEG micelles and SS-PU-b-PEG micelles as a function of drug concentration against C6 cells; (D) antitumour activity of DOX-loaded SS-PU-SS-PEG micelles and SS-PU-b-PEG micelles as a function of drug concentration against Saos-2 cells. DOX = doxorubicin; SS-PU-SS-PEG = PEG-sheddable reduction-sensitive polyurethane; SS-PU-b-PEG = PEG-unsheddable reduction-sensitive polyurethane.
