(A) Schematic drawing of click-modifiable, DXR-encapsulated polymer-caged nanobins (PCNDXR). (B) Schematic drawing of the proposed acid-triggered drug release mechanism. (C-D) Transmission electron microscopy (TEM) image of (C) intact PCNs at pH 7.4 and (D) PCNs after 72 h-incubation in pH 5.0-buffered solution at 37 °C. Both samples are stained with aqueous uranyl acetate (4 wt%) for TEM measurements.
