Fig. 3: Characterization of various MOF nanoparticles.

A FTIR spectra of ZIF-8, ZIF-8/PEG200 and ZIF-8/PEG200@Mg NPs. B XRD characterization of three different MOF NPs (a.u.= arbitrary unit). C TEM and EDS elemental mapping of C (red), N (green), O (blue), Zn (purple) and Mg (yellow) for ZIF-8/PEG200 and ZIF-8/PEG200@Mg NPs. Representative image from n = 3 biologically independent experiments with similar results. D XPS spectra of C 1 s, N 1 s, Zn 2p, O 1 s and Mg 1 s (a.u.= arbitrary unit). E N2 adsorption/desorption isotherms of ZIF-8/PEG200 and ZIF-8/PEG200@Mg NPs. F Pore width distribution of ZIF-8/PEG200 and ZIF-8/PEG200@Mg NPs. Source data are provided as a Source Data file.
