Fig. 2

a Synthetic procedure of Pt-iNOS@ZIF nanoreactor. b, c TEM images of the synthesized Pt NPs and Pt-iNOS@ZIF nanoreactor. d, e Elemental mapping and size distribution of Pt-iNOS@ZIF nanoreactor analyzed by dynamic laser scattering (DLS), scale bar: 50 nm. f X-ray diffraction (XRD) patterns of ZIF-8 and iNOS@ZIF-8 NPs. g Zeta potentials of different NPs (ZIF-8, Pt@ZIF, iNOS@ZIF and Pt-iNOS@ZIF) (n = 3 independent samples). Experiments were performed twice (d) or three times (b, c), with similar results. Data presented as means ± s.d.
