Staphylococcus aureus infection and antimicrobial resistance (AMR) to antibiotics are two significant factors that pose escalating threats public health, potentially leading persistent pain or even death. Consequently, there is an urgent need for the development of alternative antibacterial materials. In this study, we have successfully developed a biocompatible nanosystem based on hollow spherical zeolitic imidazolate framework-67 (ZIF-67 HS), which exhibits remarkable bactericidal efficacy against Gram-positive S. both in vitro vivo. Importantly, our findings demonstrate prolonged exposure subminimum inhibitory concentrations ZIF-67 HS does not induce secondary as observed with conventional antibiotics; instead, it maintains sustained susceptibility toward antibiotic-resistant strains. Multiomics analyses (including transcriptomics, metabolomics, metalomics) indicated regulates 95 genes, 261 metabolites, 2 metal elements aureus. Through bioinformatics analysis combination bioassays, demonstrated disrupted multiple essential pathways pathogen, including amino acid metabolism, iron membrane transport, reactive oxygen species (ROS), pathways. Our suggest induces bacterial death through mechanisms rather than single target highlight its long-lasting properties. This study presents valuable insights into potential nanobiomedicine eradicating bacteria elucidates related molecular mechanism.

Layered double hydroxides (LDHs) are limited by a lack of adsorption active sites and low porosity, leading to suboptimal performance in antibiotic adsorption. In this study, LDH was used as templates obtain LDO through high-temperature calcination, creating rapid mass transfer channels for LVX, thereby enhancing capacity reducing time. Subsequently, small ZIF-67 crystals were grown situ between the layers on surface LDOs, providing additional area LDO@ZIF-67 composite material. LVX removal process, synergistic effect mainly depends "memory effect" interaction various mechanisms such metal complexation, hydrogen bonding, electrostatic attraction. exhibits rate toward reaching equilibrium within 40 min, with an high 268 mg/g, surpassing values reported some literature. The process more consistent Langmuir (R2 = 0.992) pseudo-second-order kinetic model 0.991). analysis thermodynamics results showed that gradually decreased increase temperature, which belonged spontaneous exothermicity reduced degree freedom. addition, still maintains good porous crystal structure after 5 cycles adsorption-desorption, can reach 214 mg/g. This study highlights significant potential from aqueous solutions its promising application wastewater treatment.
