In the past decade, scientists sought to engineer nanomaterials with natural enzymes-like biological function, and searched for newfangled applications. Herein, we show first example of utilizing a bimetal metal–organic framework (MOF-818) platform mimicking Cu/Zn-superoxide dismutase (Cu/Zn-SOD), an important antioxidant enzyme that specifically scavenges superoxide anions. Experimental data theoretical calculations reveal high Cu/Zn-SOD-like activity MOF-818 results from synergistic...

This mechanochemical circumvents the harsh conditions often necessary for frameworks' crystallization, and hence avoids denaturation during de novo encapsulation. The covalent-linked topology tailorable large pore...
