Fig. 1. Characterization of OVA@ZIF. (A) SEM images of μ-OVA@ZIF and (B) n-OVA@ZIF. (C) PXRD diffractogram of OVA@ZIF composites. (D) Encapsulation efficiency of μ-OVA[Cy7]@ZIF and n-OVA[Cy7]@ZIF as measured by Cy7 fluorescence in the supernatant (λex = 756 nm and λem = 779 nm). (E) CLSM images of μ-OVA[Cy7]@ZIF and (F) n-OVA[Cy7]@ZIF. Brightfield images are shown on the left, fluorescent in the middle, and merged channels on the right.
