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 catalysis, which is analogous Cu/Zn-SOD. Such biomimetic process allows much higher SOD-like activity, compared reported monometallic MOFs mimics. Moreover, displays excellent stability against heating, organic solvents, denaturant treatments, should inactivate enzymes. Based on catalytic mechanism, also construct MOF-818-based colorimetric sensing phosphorylated peptides proteins detection. This work provides new insight engineering, may expedite scale-up applications nanozymes in various fields.

Abstract The deployment of metal–organic frameworks (MOFs) in a plethora analytical and bioanalytical applications is growing research area. Their unique properties such as high but tunable porosity, well-defined channels or pores, ease post-synthetic modification to incorporate additional functional units make them ideal candidates for sensing applications. This possible because the interaction analytes with MOF often results change its structure, eventually leading intrinsic physicochemical which then transduced into measurable signal. porosity allows adsorption very efficiently, while pore sizes/nature and/or installation specific recognition groups allow modulating affinity towards different classes compounds, turn lead good sensor sensitivity selectivity, respectively. Some figures are given illustrate potential MOF-based sensors most relevant application fields, future challenges opportunities their translation from academia (i.e., laboratory testing properties) industry real-world devices) critically discussed.
