(A) Schematic representations of the different FCAT/ZIF bio-composites formed by encapsulation of enzyme molecules via biomimetic mineralization or surface adsorption within/on hydrophobic (orange) or hydrophilic (blue) frameworks. (B) Confocal laser scanning micrographs showing fluorescence of different FCAT/ZIF bio-composites. (C) Catalytic activity of FCAT and different FCAT/ZIF composites. The assay was performed with FCAT concentration of 20 nM and H₂O₂ concentration of 0.20 mM. Reproduced from Liang et al. (2019) with permission from the American Chemical Society, copyright 2019.
