Structural characterizations of enzyme-incorporated composites. Scanning electron microscopy (SEM) images of nanocomposites without (a) and with (b) GOx enzyme. c High-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) image of the GOx-incorporated nanocomposite and energy-dispersive spectrum (EDS) analysis, showing the distribution of Zn and N. Scale bar is 10 nm. d Stochastic optical reconstruction microscopy (STORM) image of GOx-incorporated nanocomposites. GOx is labeled with switchable fluorescent dye, Cy5. Inset is a high-resolution image showing the distribution of GOx-Cy5 in a single nanocomposite. e, f Transmission electron microscopy (TEM) image and selected area electron diffraction (SAED) patterns of GOx-incorporated amorphous nanocomposite (e, scale bar in inset is 10 nm) and GOx-incorporated ZIF-8 (f, scale bar in inset is 20 nm). g X-ray diffraction (XRD) patterns of simulated ZIF-8, amorphous nanocomposite (am), GOx-incorporated amorphous nanocomposite (GOx-am), GOx-incorporated ZIF-8 (GOx-ZIF-8). h Pseudoradial distribution functions for ZIF-8, amorphous ZIF from experiment and corresponding fitting data. Data were extracted through Fourier transformation of the X-ray adsorption spectra (inset) obtained at the K edge of zinc. Source data are provided as a Source Data file
