Reversal of multidrug resistance in leukemia cells using a transferrin-modified nanomicelle encapsulating both doxorubicin and psoralen

Figure 1. Characterization of Tf-M-Dox/PSO nanomicelles. (A) Particle size distribution of nanomicelles. (B) A Photographs of M/DOX, Tf-M-Dox and Tf-M-Dox/PSO were taken using transmission electron microscopy after staining with 1% uranyl acetate. Scale bar = 50 nm. (C) A time course of DOX release from various formulations at 37{degree sign}C in PBS is shown (n=3/group).
