To address the serious threat of bacterial infection to public health, great efforts have been devoted to the development of antimicrobial agents for inhibiting bacterial growth, preventing biofilm formation, and sterilization. Very recently, metal–organic frameworks (MOFs) have emerged as promising materials for various antimicrobial applications owing to their different functions including the controlled/stimulated decomposition of components with bactericidal activity, strong interactions with bacterial membranes, and formation of photogenerated reactive oxygen species (ROS) as well as high loading and sustained releasing capacities for other antimicrobial materials. This review focuses on recent advances in the design, synthesis, and antimicrobial applications of MOF-based materials, which are classified by their roles as component-releasing (metal ions, ligands, or both), photocatalytic, and chelation antimicrobial agents as well as carriers or/and synergistic antimicrobial agents of other functional materials (antibiotics, enzymes, metals/metal oxides, carbon materials, etc.). The constituents, fundamental antimicrobial mechanisms, and evaluation of antimicrobial activities of these materials are highlighted to present the design principles of efficient MOF-based antimicrobial materials. The prospects and challenges in this research field are proposed.

“…There were smaller zones of inhibition for Gram‐positive bacteria than for Gram‐negative bacteria. This could be related to high peptidoglycan thickness of the cell wall in Gram‐negative bacteria reported in many studies (Shrivastava et al ; Hajibabaei et al ). The MIC results revealed that the antimicrobial activity increased by the three types of metal loading, where TM‐NZY had a higher antibacterial efficiency compared to BM‐NZY and MM‐NZY.…”

Keywords air sampling, antibacterial, indoor air quality, metal ion, nano filter, nano zeolite Y. Correspondence AbstractAims: Fibre membranes containing metals have attracted great attention because of their high antibacterial efficiency. However, comparison of antibacterial activity of fibres with multi-metals in air samples has remained understudied. Methods and Results: Different ion exchanged nano-zeolite Y (IE-NZY) of Ag, Zn and Cu was studied. Polyvinylpyrrolidine/polyvinylidene fluoride nanofibres containing various IE-NZY were synthesized according to electrospinning technique. The presence of metal ions was confirmed using XRF. The morphological properties of nanofibres were characterized by SEM. Zone of inhibition was seen between 10Á1 and 12 mm against Staphylococcus aureus and 11Á5-14Á57 for Escherichia coli. IE-NZY containing Ag, Zn and Cu had the highest antibacterial efficiency. In the air samples, there were any colonies on the media under the Ag/Cu-NZY and Zn/Cu/Ag-NZY nanofibres. Conclusions: The bacterial inhibition for nanofibres containing a three metal nano-zeolite Y (TM-NZY) is higher than bimetals (BM-NZY) types while for monometals nano-zeolite Y (MM-NZY), it was lower compared to the others. Significance and Impact of the Study: The results indicate significant antibacterial activity of ion-exchanged NZY in air sampling.

Building airtightness for acquiring greater energy efficiency have impacted indoor air quality. The control of pollution requires air filtration. Bioaerosols serve as an essential quality indicator of indoor air. The contamination of bioaerosols is a filtration barrier. The present study proposes a novel metal-organic framework (MOFs) antimicrobial air filter. This study is the first to employ Ag/MOFs/IMI in order to build an air filter for the deactivation and removal of indoor airborne microbes. The media of the Ag/MOFs/IMI/EPA filter was fabricated using the dip-coating of Ag/MOFs/IMI by imidazole and silver NPs. The deactivation and removal efficiency of the Ag/MOFs/IMI/EPA filter was assessed by bioaerosols, including "Escherichia coli" (E. coli) and "Staphylococcus aureus" (S. aureus) within a closed-loop chamber at the RH degrees of 30% and 70%. The findings suggested that the Ag/MOFs/IMI filter's removal efficiency by nearly 17.88% without significant increase in pressure drop in comparison to the raw EPA filter for the bioaerosol of S. aureus. Furthermore, the Ag/MOFs/IMI filter media's deactivation efficiency under 3% loading was obtained to be 95.62% ± 1.2% and 99.4% ± 3.25% for the bioaerosol of S. aureus at an RH of 30% and 70%, respectively. Moreover, the E. coli deactivation efficiency under an Ag/MOFs/IMI loading of 1% was found to be 68.33% ± 1.98% and 96.27% ± 3.04% for an RH of 30% and 70%, respectively. The findings indicated the Ag/MOFs/IMI filter's media to be able to effectively inactivate bioaerosols and prevent their spread from the air filter into the indoor place. Furthermore, these findings provide a pioneer contribution to the antibacterial quality development of commercial filters.
