In this work, surface molecularly imprinted polymers Co-MOF/CNT@MIPs were prepared based on metal-organic framework (MOF) and muti-walled carbon nanotubes (MWCNTs) as matrix, and norfloxacin (NOR) as template molecular. The structural characteristics of molecular imprinted polymer Co-MOF/CNT@MIP were confirmed by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS). The adsorption and selective recognition performances of Co-MOF/CNT@MIP for NOR were also investigated. The adsorption of Co-MOF/CNT@MIP for NOR reaches equilibrium at 300 min, and pseudo-second-order (PSO) model is more fit for adsorption kinetic. The adsorption capacity of Co-MOF/CNT@MIP for NOR reaches 78.6 mg/g with 1.5 mg/mL at 25℃ via the hydrogen bond interaction and “lock-key” imprinted cavities, and the D-R model is fit for adsorption isotherm. The adsorption amount decreases as increasing the temperature, which is an exothermic and spontaneous process. The imprinted polymer exhibits an excellent imprinted factor of 2.08 and high selective factor above 1.93, and it is satisfactory reusability for five cycles.

Solar-driven atmospheric water harvesting (SAWH) holds significant promise for decentralized water supply. However, its widespread application is hindered by two critical limitations: underutilization of high-humidity adsorption windows during nighttime and insufficient desorption during daytime due to the high desorption temperature requirement of conventional sorbents. To overcome these challenges, this study proposes a composite sorbent strategy by synergistically combining the low enthalpy of vaporization of LiCl with the robust adsorption capacity and stability of a metal‒organic framework (MOF, specifically Ni 2 Cl 2 (BTDD), H 2 BTDD = bis(1 H −1,2,3-triazolo[4,5- b ],[4′,5′- i ])dibenzo[1,4]dioxin). This design leverages the complementary properties to achieve lower desorption temperatures ( e.g ., < 60 o C in device level) compared to typical MOF-based systems (usually >90 o C in device level), thereby significantly reducing the energy consumption for desorption. Concurrently, the composite exhibits extended adsorption duration within the high-humidity window. Field validation across diverse climatic regions demonstrates the composite’s exceptional wide-range environmental stability and performance. The resulting SAWH device achieves a solar-to-water generation improvement up to 91% in a continental field test. This work presents a generalizable and effective pathway for enhancing SAWH performance through synergistic material engineering, enabling efficient water production and thermal control under varying environmental conditions.

Exploring CO 2 adsorption under humid conditions is crucial for practical applications. Herein, ZJU-521(Al) was synthesized using low-toxicity helical secondary building units (SBUs, [Al 5 (OH) 7 (−COO) 8 ] ∞ ) and tetrakis (4-carboxyphenyl)methane (H 4 MTTB) ligand, with excellent chemical stability. Saturated CO 2 adsorption capacities of ZJU-521(Al) reach 6.19 mmol/g at 273 K and 4.52 mmol/g at 298 K, respectively, and moderate isosteric heat of 28.23 kJ/mol, enabling low-energy regeneration. Simulation results reveal two CO 2 adsorption sites on ZJU-521(Al): site I, located near the helical SBUs and interwoven with the helical SBUs, and site II, situated near the H 4 MTTB ligand. ZJU-521(Al) can effectively separate CO 2 from the CO 2 /N 2 mixture, as identified by the ideal adsorbed solution theory values of 28.81 at 273 K and 40.83 at 298 K for CO 2 /N 2 (15/85) mixture, respectively. Dynamic adsorption experiments reveal dynamic CO 2 adsorption of 0.59 mmol/g under dry conditions and 0.54 mmol/g at 80% relative humidity (RH) for ZJU-521(Al), highlighting its moisture-resistant behavior for CO 2 adsorption under humid conditions. Most adsorbed CO 2 is readily desorbed by argon purging at 14 min (dry) and 12 min (80% RH) at 298 K, respectively. Therefore, ZJU-521(Al) emerges as a promising candidate for efficient CO 2 adsorption, separation, and desorption even under humid conditions.

Background Glutathione (GSH), the most abundant cellular non-protein thiol and a central antioxidant, plays essential roles in regulating redox homeostasis, signal transduction, and detoxification processes. Altered GSH levels are closely associated with various pathological conditions, including neurodegenerative disorders, and liver injury . Notably, tumor tissues exhibit markedly elevated GSH concentrations (up to 4-10 times higher than in normal cells), where it promotes tumor proliferation, invasion, and chemoresistance by sustaining a reduced microenvironment, these characteristics make GSH an important biomarker and therapeutic target in oncology. Results We developed a novel "switch-on" near-infrared (NIR) fluorescence nanoprobe, Ag 2 S-CH@Cu-TCPP, for the highly sensitive and selective detection and imaging of GSH. The nanoprobe was constructed by conjugating histidine-rich CH peptides to carboxyl-capped Ag 2 S quantum dots (Ag 2 S QDs), which were then self-assembled onto two-dimensional Cu-TCPP metal-organic framework (MOF) nanosheets via coordination between Cu 2+ and imidazole groups. In this design, Cu-TCPP acts as an efficient quencher for the Ag 2 S-CH fluorescence via a fluorescence resonance energy transfer (FRET) mechanism. Upon encountering GSH, the reduction of Cu 2+ to Cu + disrupts the FRET process, leading to the recovery of the NIR fluorescence signal. This nanoprobe demonstrated a low detection limit of 5.33 μM and a wide linear range from 0.625 to 10 mM for GSH quantification, with excellent selectivity, high reproducibility, and favorable biocompatibility. We successfully applied the platform for monitoring intracellular GSH levels and distinguishing between cancer cells and normal cells based on their differential GSH expression. Significance and Novelty The "switch-on" probe demonstrates excellent biocompatibility and is applicable for cellular imaging. It enables discrimination between normal and cancer cells while supporting semi-quantitative analysis of both endogenous and exogenous GSH. This work provides a novel and reliable strategy for tumor diagnosis and advanced investigations into GSH-related biological processes.

Chronic pancreatitis (CP) is a lifelong progressive fibrotic inflammatory disorder for which no effective cure is currently available. Persistent and recurrent inflammatory stimulation induced by reactive oxygen species (ROS) is a key driver of pancreatic fibrogenesis, making oxidative stress a promising therapeutic target to halt disease progression. In this study, we developed a nanosystem, HC@CeMOF, consisting of a small-sized cerium-based metal–organic framework (CeMOF) core loaded with curcumin and coated with hyaluronic acid (HA), enabling precise targeting of inflamed pancreatic tissue. HC@CeMOF exhibits a small-sized particle size along with favorable cellular and biological safety profiles. Once administered in vivo , the nanosystem exploits the specific binding affinity of HA to CD44 receptors on macrophages to selectively accumulate at inflamed pancreatic sites. Subsequently, the cerium-based nanozyme efficiently scavenges ROS through the reversible redox cycling between Ce 3+ and Ce 4+ , while the slow release of curcumin further suppresses the NF-κB signaling pathway and modulates inflammatory cytokine levels, thereby achieving synergistic anti-inflammatory and antioxidant effects. Collectively, these mechanisms substantially attenuate CP progression. This targeted ROS-scavenging and anti-inflammatory strategy holds promise as an alternative therapeutic approach for chronic pancreatitis.

Designing a reasonable structure for electrode materials is critical to increase the performance of supercapacitor . Herein, the 3D hierarchical structure composite materials contained carbon cloth, cobalt carbonate hydroxide nanorod and metal-organic frameworks derived layered double hydroxide cage hybrid arrays (CC@CCH-MOF-LDH HAs) are designed. This unique hierarchical structure and the synergistic effect of the bimetallic system improve the electrical conductivity of the material, provide more active sites and shorten the ion transport path, which are beneficial to increase the electrochemical performance of the composite material. Electrochemical measurements show that CC@CCH-MOF-LDH HAs have high specific capacitance of 1700 F g −1 at current density of 2 A g −1 , superior rate capability (even the current density was increased to 50 A g −1 , the capacitance retention rate reached 78.2%) and good cycling stability, which indicate that the CC@CCH-MOF-LDH HAs with 3D hierarchical structure is a very promising supercapacitor electrode material.

The spatial organization of enzymes in natural cells enables efficient metabolic cascades through localized microenvironments and controlled intermediate diffusion. Mimicking this compartmentalized architecture in artificial systems remains a key challenge in biocatalysis. Here, we introduce a DNA-mediated self-assembly strategy to construct the biomimetic core-satellite structure of metal-organic frameworks (MOFs) that spatially organize multiple enzymes into defined compartments. In this system, DNA bridges larger “core” MOFs and smaller “satellite” MOFs, forming ordered assemblies with tunable microenvironments tailored for individual enzymes. Using glucose oxidase (GOx) and horseradish peroxidase (HRP) as a model cascade, we demonstrate that the core-satellite structure facilitates substrate diffusion, mitigates inhibition by intermediates, and enhances overall catalytic efficiency. This platform was further applied to support multi-enzyme cascades, including the two-enzyme system of N -acetyl hexosamine 1-kinase (NahK)/UDP- N -acetylgalactosamine pyrophosphorylase (GlmU) for glycosyl donor synthesis, and the three-enzyme system of β-galactosidase (β-Gal)/GOx/HRP for sequential cascade catalysis. Compared to the single MOF system, spatially compartmentalized MOFs exhibit up to 34-fold higher activity and improved thermal, solvent, and operational stability. This work provides a versatile platform for the design of cell-inspired biocatalytic systems and underscores the potential of DNA-guided MOF assembly in constructing programmable multi-compartment enzyme reactors.

The widespread use of toltrazuril (TOL) as a low-toxicity anticoccidial agent in livestock production necessitates sensitive monitoring of its persistent metabolite, toltrazuril sulfone (TOS), which exhibits hepatotoxic and reproductive risks at subchronic exposure levels. Here, we proposed a novel electrochemical immunosensor for the ultrasensitive detection of TOS in eggs, utilizing a decorated amino-functionalized cerium metal-organic framework-gold nanoparticle (NH₂-Ce-MOF/AuNPs) nanocomposite. The NH₂-Ce-MOF was synthesized via a hydrothermal crystallization of (NH₄)₂Ce(NO₃)₆ and 2-aminoterephthalic acid, exhibiting exceptional stability and an expansive surface area. Compared to conventional electrodes, NH₂-Ce-MOF-modified electrodes promoted AuNPs nucleation and provided more active sites for HAuCl₄ deposition, while also enhancing antibody binding, thereby improving the detection sensitivity of electrochemical immunosensors. Subsequently, electrodeposited HAuCl₄ enhanced both electron transfer kinetics (charge transfer resistance decreased by 68% to a bare electrode) and bioreceptor loading capacity. Electrochemical evaluation demonstrated superior sensor performance, achieving a wide linear range of 0.05 ng/mL–100 ng/mL (R²=0.998) with an ultralow limit of detection of 33.2 pg/mL (S/N=3), representing a 3-fold improvement over conventional enzyme-linked immunosorbent assays. The electrochemical immunosensor exhibited excellent selectivity and reproducibility (relative standard deviation<10%). This platform establishes a robust foundation for TOS residues and other hazardous contaminant monitoring in complex food matrices.

Following the "MOF-protected pyrolysis" strategy, a dense carbon shell derived from ZIF tightly encapsulated MIL-53(Fe) during pyrolysis. This approach effectively prevented the high-temperature collapse of MIL-53 pore walls, thereby constructing a robust "MIL-53-carbon skeleton" composite. Furthermore, cetyltrimethylammonium bromide (CTAB) was introduced to regulate ZIF crystal growth and tailor the microporous structure. Ultimately, this process yielded nanoscale dual-MOF hybrid materials, which thus exhibit outstanding activity for both the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). In alkaline media, its ORR half-wave potential (E 1/2 = 0.926 V) significantly surpasses that of commercial Pt/C (E 1/2 = 0.826 V). For OER, the overpotential required to reach 10 mA cm −2 (η = 349 mV) is lower than that of RuO 2 (η = 368 mV). The ORR/OER potential gap (ΔE = E j10 - E 1/2 ) is only 0.653 V, which is narrower than that of the Pt/C + RuO 2 mixture (m:m = 1:1, ΔE = 0.772 V) under the same conditions. The optimally prepared composite also demonstrated excellent performance in assembled zinc-air batteries, offering a promising strategy for designing efficient bifunctional electrocatalysts.

Metal–organic frameworks (MOFs), with ultrahigh surface areas and tunable pore architectures, are promising for advanced separation membranes; however, despite advances in defect engineering for catalysis and adsorption, its potential in membrane separations remains largely unexplored. Here, we introduce a defect engineering strategy for the Zr-MOF MIP-202(Zr) through precise regulation of defect density. The defective MIP-202(Zr) was integrated with graphene oxide (GO) nanosheets via vacuum-assisted self-assembly to form hierarchical composite membranes. Notably, the defective composite membrane exhibited a two-fold increase in water permeability (up to 36.74 L m −2 h −1 bar −1 ) compared to the defect-free counterpart, while maintaining high rejection (>95%) for multiple model dyes, overcoming the conventional permeability–selectivity trade-off. The introduced defects created open sites and enhanced mass transport, collectively improving membrane hydrophilicity and water permeability. This work demonstrates defect engineering as a transformative strategy for designing high-efficiency MOF-based membranes, with significant implications for sustainable wastewater treatment and resource recovery.

High-entropy alloy (HEA) catalysts derived from metal-organic frameworks (MOFs) pave the way for efficient electrochemical energy conversion. Herein, we report the synthesis of C@FeCoNiMnMo/NF, C@FeCoNi/NF and C@FeCoNiMn/NF catalysts via a one-step hydrothermal process coupled with subsequent calcination. Structural and morphological characterizations (XRD, XPS, SEM, and TEM) verifies the successful formation of a carbonized MOF-derived high-entropy alloy with uniform metal dispersion. Among these catalysts, C@FeCoNiMnMo/NF exhibits superior urea oxidation reaction (UOR) activity, achieving E 10 = 1.24 V and E 100 = 1.32 V (corresponding to 10 and 100 mA·cm −2 , respectively), with excellent durability over 30 h of continuous operation. The enhanced adsorption of key intermediates induced by Mo doping, as evidenced by both electrochemical analysis and DFT calculations, is identified as the primary factor responsible for the accelerated UOR kinetics. This work establishes an innovative approach for the rational design of MOF-derived HEA catalysts, which boosts the efficiency of urea-assisted hydrogen production from water.

A sensitive voltammetric platform for determination of pefloxacin. • UiO-67/MWCNT-COOH exhibited significant synergistic effect toward pefloxacin. • Wide linear range (0.01–10 μM), low LOD (5.0 nM) and good stability (30 days). • High sensitivity in the detection of pefloxacin in lake water and honey. Developing a simple and efficient detection method for pefloxacin (PEF) is crucial for environmental monitoring and food safety assurance. In this study, we designed a novel electrochemical sensor for PEF detection by integrating zirconium-based metal-organic frameworks (UiO-67 MOFs) with carboxylated multi-walled carbon nanotubes (MWCNT-COOH) through a two-step hydrothermal and ultrasonic-assisted strategy. The coordination of the carboxyl groups of MWCNT-COOH with the unsaturated metal sites on the zirconium clusters of UiO-67, and the strong electrostatic attraction between PEF and the negatively charged composite surface, as well as strong π-π stacking interactions between the aromatic ring of PEF and the benzene rings of the organic ligands in UiO-67 and the graphite surface of MWCNT-COOH, collectively contribute to the efficient accumulation and sensitive detection of PEF. The sensor demonstrated a wide linear range (0.01–10 μM), an ultralow detection limit (0.005 μM), and outstanding overall sensing performance. When applied to real-world samples, including lake water and honey, the method achieved satisfactory recovery (94.48% − 108.9% and 100.9% to 106.4%, respectively), confirming its practical applicability for monitoring PEF in environmental and food matrices. A sensitive electrochemical sensing platform was developed for the detection of trace pefloxacin residues in lake water and honey by integrating zirconium-based metal-organic frameworks (UiO-67 MOFs) with carboxylated multi-walled carbon nanotubes (MWCNTs-COOH).
