Fig. 2. (a) UV-vis spectra of ethanolic solutions of void ZIF-8, OMC@ZIF-8, BMDM@ZIF-8 and OMC + BMDB@ZIF-8. For each OMC-containing sample the OMC concentration was 5 μg mL−1, and for each BMDM-containing sample, the BMDM concentration was 5 μg mL−1. (b) Fluorescence spectra under 228 nm excitation (c) powder XRD patterns and (d) FTIR spectra of ZIF-8, OMC@ZIF-8, and BMDM@ZIF-8 nanocapsules.
