Protocol to assemble metal-phenolic framework nanoparticles based on polyphenol-mediated biomimetic mineralization for wound healing in rats

Summary: Here, we present a protocol for controllable biomimetic mineralization at the nano-scale, simulating natural ion-enriched sedimentary mineralization. We describe steps for treatment of metal-organic frameworks with polyphenol-mediated stabilized mineralized precursor solution. We then detail their use as templates to assemble metal-phenolic frameworks (MPFs) with mineralized layers. Furthermore, we demonstrate the therapeutic benefits of MPF delivery by hydrogel to the full-thickness skin defect model in rats.For complete details on the use and execution of this protocol, please refer to Zhan et al. (2022).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
