Microenvironment-Engineered Biocatalytic Metal-Organic Framework Nanomotors for Selective and Transformative Water Decontamination.

ABSTRACT: Catalytically powered micro-/nanomotors have become a compelling alternative to conventional catalysts for active and efficient removal of environmental pollutants in water remediation. We developed a novel biocatalytic nanomotor system by encapsulating catalase and peroxidase enzymes into metal-organic frameworks (MOFs), demonstrating exceptional speed and facilitated motion-induced convection and mass transfer. Leveraging a synergistic structural etching and surface engineering strategy using tannic acid (TA), we create a tailored microenvironment of the MOF's framework with charge-selective and nanoconfinement properties. Both experimental and simulation results indicate that microenvironment modulation of MOF matrix could act in synergy with the encapsulated enzymes and significantly i
