Fig. 2: Structural characterization of ZAF(Ser).

a SEM images of ZAF(Ser). The experiment was independently repeated three times with similar results. b HAADF-STEM images of ZAF(Ser) and the corresponding EDX elemental mapping images for C, N, O and Zn. The experiment was independently repeated three times with similar results. c PXRD patterns for ZAF(Ser), ZAF and ZnSer. d Nitrogen sorption curves for ZAF, ZAF(Ser), ZAF(Cys) and Ser@ZAF. The inset shows confocal laser scanning microscopy images of fluorescein molecules entering the pores of ZAF(Ser) (left) and ZAF (right). The experiment was independently repeated three times with similar results. High-resolution Zn 2p XPS spectra (e) and N 1s XPS spectra (f) of ZAF(Ser), ZAF and ZnSer. Normalized Zn K-edge XANES spectra (g) and corresponding Fourier transform EXAFS fitting curves (h) of ZAF(Ser) and ZAF. i Wavelet transforms for the k3-weighted Zn K-edge EXAFS signals of ZAF(Ser) and ZAF. Source data are provided as a Source Data file.
