As an endocrine disruptor, bisphenol A (BPA) has many adverse effects on environmental safety and human health. Aiming at the existing problems at the current detection methods, herein, a 3D metal‐organic framework (Ni‐MOF) was fabricated as a carrier to achieve BPA aptamers immobilization inside its array channels under Mg2+ regulation. Based on the reversible quenching of 6‐FAM (6‐carboxyfluorescein) fluorescence labeled on the BPA aptamers during the encapsulation process, a fluorescent aptamer sensing platform was constructed for the quantitative detection of BPA in water. Morphology analysis, VASP (Vienna ab‐initio simulation package) and other kinetic simulations were performed to elaborate the mechanism of the influence of pore size, medium ions, etc. on the recognition process. Due to the in‐hole fixation strategy of aptamers, Ni‐MOF played an obvious protection aptamers. Not only the activity of BPA aptamer@MOF composite was maintained more than 50 % in complex environments such as pH 3.0–11.0, 30–70 °C and organic solvents, but also the aptamer was protected from nuclease hydrolysis under physiological conditions. The stability and application range of the sensor are greatly improved, detection limit of 0.34 μM. The result was expected to provide theoretical guidance for the rapid detection of pollutants in complex environments.

The present study focuses on the synthesis of copper‐based benzene dicarboxylic acid (Cu BDC) metal‐organic frameworks (MOF) and its application as a catalyst in the synthesis of 6H‐chromeno[4,3‐b] quinoline derivatives via Aza–Diels–Alder reactions. Aromatic amines and derivatives of O‐propargylated salicylaldehyde are employed in this synthetic strategy. The synthesized Cu BDC MOFs were studied using powder X‐ray Diffraction (PXRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and energy‐dispersive X‐ray (EDX). The Cu BDC MOF's efficiency and reusability as catalysts have been demonstrated in the Aza‐Diels‐Alder reaction for the first time. Additionally, we proposed a mechanism for the Cu BDC MOF‐mediated synthesis of chromenoquinolines, considering experimental results and literature reports.

The increasing prevalence of health concerns has sparked a demand for advanced health monitoring tools, which is a significant challenge for researchers. Analysis of biofluid samples and biomarker monitoring is vital for comprehensive health assessment. In this context, metal–organic frameworks (MOFs) have emerged as one of the leading materials for developing cutting‐edge artificial sensors. These unique MOFs have been developed from metallic and organic linkers and consist of tunable pores and dynamic surface areas, attracting various guest molecules to participate in developing advanced electrochemical devices. This study is a gateway to a world where MOF designs transcend mere inventions, morphing into electric marvels that revolutionize urine sample monitoring. From the inception and design to the fabrication of MOF sensors tailored for electrochemical applications, this study prides itself on elucidating the factors affecting MOF‐based electrical devices and sensors. Moreover, the focus is placed on conductivity, electrode properties, and recent state‐of‐the‐art urine sample analysis, highlighting the pivotal role biomarkers play in honing the resilience and performance of the sensors. Finally, this study is specific to electrochemical sensors used for urine analysis. It will attract researchers to develop new portable tools for health monitoring by analyzing urine samples.
