Background The Fenton-like reaction is a highly potential advanced oxidation process. The photo-Fenton-like reaction formed by the combination of photocatalytic advanced oxidation process, which combines their advantages, breaks the original Fenton-like reaction rate bottleneck. Methods In this study, an ultra-thin MOF (Cu-TCPP(BA)-MOF) with porphyrin as the ligand and copper as the metal node was synthesized via a simple one-pot method for the first time. Significant Findings It activates Peroxymonosulfate (PMS) under visible light to degrade 10 mg/L Rhodamine B which can be completely degraded within 40 min. The pseudo-first-order rate constant of RhB is 0.9011 min −1 , being 5 folds larger than this for CuO as catalysts. ESR analysis shows that Cu-TCPP(BA)-MOF/PMS/vis system produces a large amount of non-radical 1 O 2 . Also under visible light, with E. coli concentration of 10 7 cfu/mL, it can be completely inactivated within 50 min. Dilution spreading plate method and Fluorescence spectroscopy confirmed the complete death of bacteria. In terms of mechanism, the ultra-thin MOF provides a large number of Cu 2+ active sites. Under visible light, the cycle between Cu 2+ and Cu + is accelerated and the pathways that produce reactive oxygen species (ROS) is changed, thereby improving the performance of contaminant treatment and sterilization.

Owing to the internal correction function and good resistance to complex factors, dual-signal electrochemical sensors have abilities to avoid false positives. In this work, Cu-MOF and MnCO 3 were combined and further prepared the Cu 2+ and Hg 2+ dual-signal electrochemical sensor for ultra-sensitive detection of Hg 2+ . Notably, beyond the commonness of the general MOFs, Cu-MOF could undergo oxidation–reduction to provide an internal reference signal. MnCO 3 , a porous structure with good electrocatalysis, exhibits an obvious signal amplification effect on the detection of Hg 2+ . Differential pulse voltammetry was applied for the detection of Hg 2+ . The current signal of Cu 2+ and Hg 2+ reduced regularly with Hg 2+ concentration decreased. Under optimized conditions, the LOD of Hg 2+ was calculated around 6.82 nM with a linear range of 0.10 ∼ 2.50 μM. The proposed sensor was proven to show satisfactory anti-interference, stability, and reliability, which is promising for the ultra-sensitive detection of Hg 2+ in real life.

In this study, the activation of peroxymonosulfate (PMS) and selective degradation of nonsteroidal anti-inflammatory drugs were investigated using hydrophobically modified Fe 3+ @Cu-MOF. The Fe 3+ @Cu-MOF-CTAB/PMS system demonstrated high-efficiency, achieving near-complete degradation of diclofenac within 120 min. The degradation rate constants for diclofenac, ibuprofen, and naproxen were 0.0048, 0.00103, and 0.00046 min −1 , respectively, positively correlated with their hydrophobicity. Longer hydrophobic surfactant chains in Fe 3+ @Cu-MOFs lead to greater initial adsorption of diclofenac, enhancing degradation efficiency upon the introduction of PMS. The Fe 3+ @Cu-MOF-CTAB/PMS system removes over 80 % of diclofenac in various water matrices, showing optimal efficiency in acidic environments but reduced effectiveness with competing anions. Post-degradation changes in the oxidation states of copper and iron in the MOF structure indicated a synergistic redox mechanism essential for PMS activation. The hydroxylation and C-N bond cleavage in diclofenac were key degradation pathways. This study highlights the potential of hydrophobically modified Fe 3+ @Cu-MOFs in water treatment, providing insights into the interplay between material design, hydrophobic interactions, and catalytic performance.

As an alternative to natural enzymes , artificial enzymes based on nanomaterials have attracted a lot of attention owing to their outstanding catalytic activity and high stability as well as low cost. Cu-MOF loaded with platinum nanoparticles (labeled Cu-MOF@Pt) was prepared by simple one-step wrapping method using platinum nanoparticles, copper nitrate trihydrate and 1,3,5-tricarboxybenzene. It was confirmed that Cu-MOF@Pt exhibits peroxidase-like activity, which can quickly catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) and produce blue oxidized TMB (oxTMB) in the presence of hydrogen peroxide (H 2 O 2 ). Additionally, steady-state kinetics showed that Cu-MOF@Pt exhibits stronger appetency to TMB and H 2 O 2 compared with horseradish peroxidase . Thanks to the peroxidase-like activity of Cu-MOF@Pt, a highly selective colorimetric method for glucose detection has been successfully established, the linear range is 2–15 mM (R 2 =0.9999) and the Limit of Detection (LOD) is 0.42 mM, with a detection range that meets clinical needs. Moreover, its good intra- and inter-assay precision and excellent stability make the results of glucose detection very reproducible. The detection performance of 90.09% was still maintained at 4 ℃ for 2 months. In conclusion, a new nanocomposite was successfully prepared and its selective detection ability for glucose was proved, which established a good basis for the clinical development of new enzymes for biosensors .

“Green Synthesis” has been broadly applied in drug synthesis and nanomaterial preparation. The integration of automated micro-synthesis and high-throughput screening systems is a key way to achieve the goal of green manufacturing. Here, a one-click green synthesis platform is designed that integrates droplets arrays-based micro-synthesis for Raman enhancement performance high-throughput screening of MNPs@Cu-MOF (AuNPs@, AgNPs@, PtNPs@Cu-MOF) under room temperature and normal pressure. The fully integrated ultrasound units can achieve rapid multi-component mixing in the droplet array systems, and significantly accelerate materials growth as well as enhance encapsulation of noble metal nanoparticles into Cu-MOF structures. Based on such integrated systems, structures with high Raman enhancement performance can be high-throughput evaluation and easily screened out. The results indicated that the AgNPs@Cu-MOF exhibited the best Raman enhancement performance, which is ≈8 times higher than pure AgNPs. Such a green and integrated platform provides a way for automated multi-type composites fabrication, which can be expanded to multiple fields in the future via combined robotic platforms and artificial intelligence technology.

The performance of aqueous zinc-ion batteries is frequently hindered by anode-related issues such as uncontrolled dendrite formation and side reactions. Metal–organic frameworks (MOFs), characterized by their highly ordered porous structures, remarkably large specific surface areas, and tunable active sites, offer a promising solution by regulating Zn2+ flux and promoting uniform Zn deposition. In this study, a Cu-MOF was synthesized in situ on carbon cloth (CM-C) and functioned as an ion-buffering layer within the battery. This innovative configuration significantly mitigates side reactions, achieving an extended cycle life of nearly 800 h at a high current density of 10.0 mA cm–2 (areal capacity: 10.0 mA h cm–2) and nearly 1200 h at 5.0 mA cm–2. After 2000 cycles at 5.0 mA cm–2, the battery demonstrated an average Coulombic efficiency of 99.3%. Additionally, the full battery containing CM-C demonstrated enhanced capacity and stability. This simple and novel structure provides new possibilities for enhancing the cycling stability of zinc-ion batteries.

Due to the high toxicity of aflatoxin B1 and its risks to human health, we developed a click reaction-mediated automated fluorescent immunosensor (CAFI) for sensitive detection of aflatoxin B1 based on the Cu(I)-catalyzed click reaction. With its large specific surface area, a copper-based metal–organic framework (Cu-MOF) was synthesized to adsorb and enrich the copper ion (Cu(II)) and then load the complete antigen (BSA-AFB1). After the immunoreaction, Cu(II) inside the Cu-MOF-Antigen conjugate would be reduced to Cu(I) in the presence of sodium ascorbate, which triggered the click reaction between the fluorescent donor-modified DNA and the receptor-modified complementary DNA to lead to a fluorescence signal readout. The whole reaction steps were finished by the self-developed automated immunoreaction device. This CAFI method showed a limit of detection (LOD) of 0.48 pg/mL as well as a 670-fold enhancement in sensitivity compared to conventional ELISA, revealing its great potential in practical applications and automated detection.

Developing a reliable detection method with high performance for pefloxacin (PFL) is crucial for environmental protection and food safety. However, this remains a challenge. In this study, a new portable electrochemical sensor with a smartphone readout system based on a modified Cu-MOF was designed for PFL detection. The modified Cu-MOF was prepared using a two-step post-synthetic modification strategy. Firstly, thiourea (Th) was doped into the Cu-MOF framework using a solvothermal method, and then the Th-Cu-MOF was further functionalized with MWCNTs using a self-assembly method. X-ray photoelectron spectroscopy combining with chronocoulometry technique and electrochemical impedance measurements revealed that Th not only increased the Cu-MOF’s affinity to PFL but also acted as a bridge, enhancing the interaction between Cu-MOF and MWCNTs. This led to a MOF-based nanocomposite with significantly improved conductivity and specific catalytic properties for PFL. After optimizing detection conditions, the portable sensor showed wide linearity range (9 nM–2.5 μM), excellent selectivity, good stability and a low detection limit (2.6 nM) surpassed that of HPLC in the detection of PEL by utilizing square wave voltammetry technique. In real sample analysis of pond water, shrimp flesh and pork, the portable sensor showed good recoveries (87.92 %–104.4 %), which were comparable to those of HPLC and an electrochemical sensor with a classical three-electrode configuration. This demonstrates that the sensor holds excellent potential for on-site monitoring of PFL in aquaculture.

Solid-state lithium batteries using solid composite polymer electrolytes (CPEs) with great thermal and mechanical stabilities are believed to be the next-generation advanced electrochemical devices, but they suffer from low ionic conductivity at room temperature and a poor interface between the electrode and the electrolyte. Herein, we present a poly(ethylene oxide) (PEO)-based CPE allowing rapid Li+ migration enabled by coordinating the anions on the exposed metal sites of a metal–organic framework (MOF). The CPE contains MOF-74 fillers, a PEO matrix, and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). Owing to the strong anchoring effect of MOF-74 fillers on TFSI– verified by calculations and measurements, the CPE exhibits a high ionic conductivity (5.5 × 10–5 S·cm–1 at 30 °C), a wide electrochemical stability (4.8 V), and an improved Li+ transference number (0.36). Besides, the adjusted local current density promotes the interfacial stability against the Li anode in a Li symmetric battery, which performed well at a current density of both 0.2 and 0.4 mA cm–2. With these advantages, the all-solid-sate LiFePO4 battery fabricated exhibited stable cycling performances (161 mA h g–1 and maintained 152 mA h g–1 after 300 cycles at 0.5 C). This strategy gives fresh reference to the utilization of different MOFs and polymers in building high-performance solid-state lithium batteries.

Unpredictable pandemics are likely to pose a significant global threat in the future, and biologically protective textiles will play critical roles in controlling the spread of pathogens during outbreaks. Herein, we present a novel metal–organic framework (MOF) composed of repeating units of a Cu(II)/(L-Cys) 2 complex formed through coordination bonds between Cu(II) and L-Cys, while being interconnected by ionic bonds involving Cu(II) and the carboxylate group of L-Cys. After covalently embedding the MOF nanofibers onto cotton fiber surfaces, the resulting fabrics exhibit remarkable virucidal and antibacterial capabilities. Remarkably, even after 200 friction or 50 laundering cycles, the high antiviral ability to inactivate all phi- × 174 within 10 min was maintained, and the bacterial reduction rate against E. coli and S. aureus remained nearly at 100%. The remarkable virucidal effect of the L-Cys@Cu MOF structure is elucidated through a series of α-amylase denaturation simulation tests, providing the first experimental demonstration of the antiviral mechanism, whereby MOF nanofibers induce protein denaturation to inactivate viruses. Moreover, cytotoxicity assessments confirm that the fabrics adorned with MOF nanofibers are safe for human skin. These advantages are promising for the development of protective textiles, highlighting the great potential of nanoscience in combating pandemics. Graphical Abstract

Disruptions in metal balance can trigger a synergistic interplay of cuproptosis and ferroptosis, offering promising solutions to enduring challenges in oncology. Here, we have engineered a Cellular Trojan Horse, named MetaCell, which uses live neutrophils to stably internalize thermosensitive liposomal bimetallic Fe-Cu MOFs (Lip@Fe-Cu-MOFs). MetaCell can instigate cuproptosis and ferroptosis, thereby enhancing treatment efficacy. Mirroring the characteristics of neutrophils, MetaCell can evade the immune system and not only infiltrate tumors but also respond to inflammation by releasing therapeutic components, thereby surmounting traditional treatment barriers. Notably, Lip@Fe-Cu-MOFs demonstrate notable photothermal effects, inciting a targeted release of Fe-Cu-MOFs within cancer cells and amplifying the synergistic action of cuproptosis and ferroptosis. MetaCell has demonstrated promising treatment outcomes in tumor-bearing mice, effectively eliminating solid tumors and forestalling recurrence, leading to extended survival. This research provides great insights into the complex interplay between copper and iron homeostasis in malignancies, potentially paving the way for innovative approaches in cancer treatment.

A chromogenic system utilizing a novel bacteriophage-integrated nanozyme was established for Proteus penneri detection. Initially, a novel bacteriophage PpZDSS02 was isolated and identified, demonstrating exceptional biological properties and harboring genes that exhibit specific recognition ability. Afterwards, a PpZDSS02-integrated Cu-MOF nanozyme (Cu-MOF@PpZDSS02) with peroxidase-mimicking activity was prepared, catalyzing 3, 3′, 5, 5′-tetramethylbenzidine (TMB) chromogenic reaction. Its peroxidase-mimicking activity can be modulated by P. penneri . Interestingly, low concentration of P. penneri can enhance its activity and high concentration of P. penneri inhibits its activity. Based on it, a visual quantification method with high sensitivity and specificity for P. penneri was achieved, offering a low limit of detection (3.3 CFU·mL −1 ). Moreover, Cu-MOF@PpZDSS02-based chromogenic system shows exceptional performance in the detection of authentic food samples, achieving ideal recoveries (89.00 % ∼ 111.81 %). These results indicate the potential application of Cu-MOF@PpZDSS02-based chromogenic system for colorimetric detection of P. penneri .
