Fig. 2. Time-dependent stability study of ZrMOF, ZrMOF-PAA, and ZrMOF-PAC in phosphate buffer saline.

Fig. 2.

(A), (C), and (E) are digital camera pictures of the supernatant of ZrMOF, ZrMOF-PAA, and ZrMOF-PAC at different time points after being suspended in 1X PBS. (B), (D), and (F) are corresponding UV-vis spectrum of the dissociated TCPP in the supernatant after suspending ZrMOF, ZrMOF-PAA, and ZrMOF-PAC in 1X PBS for different periods of time (0.1, 0.5, 1, 5, 10, and 24 h). (G) Standard curve of TCPP in 1X PBS for TCPP quantification. (H) Dissociation comparison of ZrMOF, ZrMOF-PAA, and ZrMOF-PAC in 1X PBS.
