Figure 3. Evaluation of MOF ZIF-8 biocompatibility using hepatic organoids. Hepatic organoids at (A) 0 h and (B) 96 h after a series of ZIF-8 concentration loading; (C) Assessment of the Histological assessment (H&E staining) of hepatic organoids at 96 h after a series of ZIF-8 concentrations. All bright-field images were acquired at 4× magnification with a 500 μm scale bar. MOF: Metal–organic framework; ZIF-8: zeolitic imidazolate framework-8; H&E: hematoxylin and eosin.
