Chemical warfare agents represent a severe threat to mankind and their efficient decontamination is a global necessity. However,traditional disposal strategies have limitations, including high energy consumption, use of aggressive reagents and generation of toxic byproducts. Here, inspired by the compartmentalized architecture and detoxification mechanism of bacterial microcompartments, we constructed oil-in-water Pickering emulsion droplets stabilized by hydrogen-bonded organic framework immobilized cascade enzymes for decontaminating mustard gas simulant(2-chloroethyl ethyl sulfide, CEES) under sweet conditions. Two exemplified droplet systems were developed with two-enzyme(glucose oxidase/chloroperoxidase) and threeenzyme(invertase/glucose oxidase/chloroperoxidase) cascades, both achieving over 6-fold enhancement in decontamination efficiency compared with free enzymes and >99% selectivity towards non-toxic sulfoxide. We found that the favored mass transfer of sugars and CEES from their respective phases to approach the cascade enzymes located at the droplet surface and the facilitated substrate channeling between proximally immobilized enzymes were key factors in augmenting the decontamination efficacy. More importantly, the robustness of immobilized enzymes enabled easy reproduction of both the droplet formation and detoxification performance over 10 cycles, following long-term storage and in far-field locations.

Dear Editor,Free spike protein of SARS-CoV-2 alone can cause abnormal energy metabolism(Table S1 in Supporting Information), and limited research suggested a potential correlation between spike-induced mitochondrial damage and the ACE2 receptor(Lei et al., 2021; Yang et al., 2023). In order to further explore the mechanisms involved, we observed that the wild-type S1 protein of SARS-CoV-2 exerts a more potent inhibitory effect on host cell ATP compared to the wild-type S protein, S2protein, the Omicron variant S1 protein and HCoV-NL63 S1protein in HLMVEC and 293T cell lines(Figure 1A and B),indicating the importance of exploring the mechanism by which the S1 protein causes ATP decrease. Meanwhile, the S1protein did not lead to significant changes in cellular lactate levels, indicating that its primary mechanism involves impairing oxidative phosphorylation and mitochondrial damage(Figure 1C and D).
