“…The DNA damaging effect of ZIF-8@RMSN was further investigated through gel electrophoresis analysis. [52,53] The results are shown in Figure S13A. Compared with the clearly visible DNA bands of the untreated group and the BAC/ZIF-8 treated group, after ZIF-8@RMSN treatment, almost no band was observed.…”

Bacterial infection is a major threat to public health. Nanotechnology offers a solution by combining nanomaterials with antibacterial agents. The development of an effective nanocomposite against drug‐resistant bacteria such as methicillin‐resistant Staphylococcus aureus (MRSA) is highly important yet challenging. Here, an anti‐MRSA core–shell structure is designed, containing antibacterial zeolitic imidazolate framework‐8 (ZIF‐8) as the core and bactericidal benzalkonium chloride (BAC) templated rough‐surface mesostructured silica nanocomposite (RMSN) as the shell. The resultant ZIF‐8@RMSN nanocomposite exhibits sustained release of BAC and zinc ions, effective disruption of the bacterial membrane, generation of oxidative damage of bacterial DNA, leakage of intracellular components, and finally bacterial death. Furthermore, the synergistic antibacterial mechanisms lead to enhanced biofilm elimination performance. In addition, the ZIF‐8@RMSN‐modified band‐aid effectively combats MRSA infection in vivo. This work has provided a promising nanocomposite against MRSA‐related infections.

“…Shekhawat et al [150] showed that the combined UV and chlorine (2.5 mg/ L of chlorine and 27 mJ/cm 2 UV) significantly decreased the concentrations of total tri-halomethanes (THMs) and total haloacetic acids (THAAs) in wastewater, curbing the potential harmful impacts of their presence in aquatic environments. Chlorination and UV can effectively remove ARB from wastewater effluents, but ARGs cannot be removed on large a scale [151,152]. The combination of UV and chlorine produces hydroxyl radicals (HO•) and radicals of reactive chlorine species (RCS) (Cl•; E h = 2.4 V, Cl 2 • − ; E h = 2.0 V, ClO•; E h = 1.5-1.8 V), and these RCS were found to be responsible for the removal of ARGs [153].…”

Antimicrobial resistance (AMR) is a serious problem for modern society, not only associated with clinical environments, but also the natural environment. Conventional wastewater treatment plants (WWTPs) are important nodes for the dissemination of antibiotic resistance to the aquatic environment since they are reservoirs of antibiotic-resistant bacteria (ARB), antibiotic resistance genes (ARGs), and antibiotic residues. WWTPs are not designed to remove these antibiotic resistance determinants from wastewater, and as a result, they are present in treated effluent, leading to environmental and public health concerns regarding wastewater disposal and reuse. Additional treatments combined with conventional WWTPs can be barriers to the spread of AMR to the environment. In order to understand the effect of wastewater treatment methods on the removal of ARB and ARGs, an extensive bibliographic study was conducted. This review summarizes the efficiency of conventional disinfection methods, tertiary wastewater treatment, and advanced oxidation processes (AOPs) to remove ARB and ARGs from wastewater. In the context of the revised Urban Wastewater Treatment Directive 91/271/EEC, further studies are needed on the removal potential of AOPs on a full-scale, as they offer great potential for the removal of ARB and ARGs with a low formation of toxic by-products compared to conventional disinfection methods.

“…The library of IME for OEOR should be more enriched. Despite many progress have been achieved in recent years, exploration of its application potential toward other kinds of organics with rich functional groups and complicate structures (e.g., degradation of antibiotics, [194][195][196] synthesis of medicines including quinolines, [197] finerenone, [198] narural products, [199] and peptides, [65] and of fine chemicals like indole derivatives [67] ) is still highly desirable and necessary. Properties of these reactants vary vastly from polarity, chain length, and configuration, hydrophilicity and hydrophobicity, solubility to adsorption strength etc.…”

Conventional designing principal of electrocatalyst is focused on the electronic structure tuning, on which effectively promotes the electrocatalysis. However, as a typical kind of electrode–electrolyte interface reaction, the electrocatalysis performance is also closely dependent on the electrocatalyst interfacial micro‐environment (IME), including pH, reactant concentration, electric field, surface geometry structure, hydrophilicity/hydrophobicity, etc. Recently, organic electro‐oxidation reaction (OEOR), which simultaneously reduces the anodic polarization potential and produces value‐added chemicals, has emerged as a competitive alternative to oxygen evolution reaction, and the role IME played in OEOR is receiving great interest. Thus, this article provides a timely review on IME and its applications toward OEOR. In this review, the IME for conventional gas‐involving reactions, as a contrast, is first presented, and then the recent progresses of IME toward diverse typical OEOR are summarized; especially, some representative works are thoroughly discussed. Additionally, cutting‐edge analytical methods and characterization techniques are introduced to comprehensively understand the role IME played in OEOR. In the last section, perspectives and challenges of IME regulation for OEOR are shared.
