Characterization of DA-P-SS-T/PTX nanomicelles and stimulus-responsive release of PTX. A TEM images of nanomicelles. B The changes in the zeta-potential of P-SS-T/PTX and DA-P-SS-T/PTX nanomicelles during incubation in PBS at pH 6.5 and 7.4. C The changes in the size of nanomicelles during incubation in PBS containing 10% FBS at 37 °C for 90 h. D In vitro PTX release from DA-P-SS-T/PTX nanomicelles in PBS in the presence of various GSH concentrations
