“…Overall, the results obtained with these COF composite-based electrochemical sensors show detection limits in micromolar (μM) values and wide linear ranges, which are promising for clinical chemistry and biomedical uses, especially for separate or simultaneous AA, DA, and UA detection in human fluid samples. Compared with their MOF counterpart, COF-based electrochemical sensors presented a similar performance in the detection of UA, DA and AA in a simultaneously way, however, MOFs display the particularity of provide a way to detect each analyte individually in function of pore size and redox activity of metal centres, [92][93][94] which is difficult with COFs materials. On the other hand, the comparison with metallic oxide composites demonstrate a superior performance with low detection limits under 0.25 μM in most cases, whereas metallic oxides presented high LODs, and null capability of detecting these analytes individually.…”

Covalent organic frameworks (COFs) have emerged as a ground-breaking class of porous crystalline materials, offering unparalleled potential in the realm of electrochemistry. Their exceptional properties, including high surface area, tunable porosity, chemical stability, and redox properties make COFs uniquely suited for advanced electrochemical sensors. This review delves into the main aspects of COFs, exploring their synthesis methods, intrinsic properties, and pivotal role in enhancing electrochemical sensor performance. Moreover, the latest advancements in COF-based electrochemical sensors will be discussed, highlighting their versatile applications in detecting a wide array of analytes such as biomolecules, metal ions, and organic pollutants. By summarizing the significant challenges and promising opportunities in this field, we underscore the transformative potential of COFs in electroanalytical chemistry and their seamless integration into next-generation electronic devices.

Micro‐/nanomotors (MNMs) in water remediation have garnered significant attention over the past two decades. More recently, metal‐organic framework‐based micro‐/nanomotors (MOF‐MNMs) have been applied for environmental remediation; however, a comprehensive summary of research in this research area is yet to be reported. Herein, a review is presented to cover the recent advances in MOF‐MNMs and their various applications in wastewater remediation. The review presents a comprehensive introduction to MNMs, including different propulsion approaches, fabrication, and functionalization strategies, in addition to the unique features of MOF‐MNMs. The conception and various synthetic routes of MOF‐MNMs are extensively covered and the implementation of MOF‐MNMs in water‐related applications, including adsorption, degradation, sensing, and disinfection of different pollutants, is in depth discussed. Meanwhile, the propulsion and mechanism of action behind each MOF‐MNM are systematically studied. Finally, the review provides insights into the challenges and perspectives to build more effective MOF‐MNMs to cover versatile applications for wastewater treatment.
