“…Numerous techniques such as adsorption, oxidation, membrane separation and flocculation have been developed nowadays for water treatment. [186][187][188] PHMB is typically used as a disinfectant/biocide to kill the microorganisms in water. 189,190 Ma and colleagues developed a dual-functional magnetic porous microsphere chemically modified with PHMB for highly efficient and recyclable water disinfection and dye removal.…”

“…Total organic synthesis was used to construct 2D (graphene nanorods) GNR with lengths up to 12 nm [ 126 ]. The restricted size range of PAHs, however, may impact graphene quality by lowering graphene solubility and causing side reactions as a consequence of increased molecular weight [ 127 ]. It was shown by Yan et al [ 128 ] that the resultant graphene possesses stable dispersibility despite its huge size, which solved these problems.…”

Wearable sensors and invasive devices have been studied extensively in recent years as the demand for real-time human healthcare applications and seamless human–machine interaction has risen exponentially. An explosion in sensor research throughout the globe has been ignited by the unique features such as thermal, electrical, and mechanical properties of graphene. This includes wearable sensors and implants, which can detect a wide range of data, including body temperature, pulse oxygenation, blood pressure, glucose, and the other analytes present in sweat. Graphene-based sensors for real-time human health monitoring are also being developed. This review is a comprehensive discussion about the properties of graphene, routes to its synthesis, derivatives of graphene, etc. Moreover, the basic features of a biosensor along with the chemistry of sweat are also discussed in detail. The review mainly focusses on the graphene and its derivative-based wearable sensors for the detection of analytes in sweat. Graphene-based sensors for health monitoring will be examined and explained in this study as an overview of the most current innovations in sensor designs, sensing processes, technological advancements, sensor system components, and potential hurdles. The future holds great opportunities for the development of efficient and advanced graphene-based sensors for the detection of analytes in sweat.

“…Therefore, the development of a fast, convenient, and cost-effective detection and adsorption method is extremely necessary. Many advanced sensory and adsorption materials, including polymeric probes, quantum dots, supramolecular assemblies, AIE-Active compounds, graphene oxides, and carbon nanomaterials, have already been developed. − However, most of these materials have issues, such as tough synthesis, efficiency, and selectivity challenges. In this context, metal–organic frameworks (MOFs) are believed to be one of the promising materials for diminishing these challenges as a result of their noteworthy structural features like high surface area and wide range of pore environment modulation, which could favor host–guest supramolecular interactions. − However, some concerns, especially signal-to-noise ratio and chemical/water stability, should also be taken into account before application.…”

With increasing global industrialization, it is urgent and challenging to develop multifunctional species for detection and adsorption in the environment. For this purpose, a novel anionic heterometallic organic framework, [, is hydrothermally synthesized based on chelidamic acid (H 3 CAM). Single crystal analysis shows that CaEuCAM features two different oxygenrich channels along the c-axis in which one CAM 3− bridges two sextuplecoordinated Ca 2+ and two octuple-coordinated Eu 3+ with a μ 4 -η 1 : η 1 : η 1 : η 1 : η 1 : η 1 new chelating and bridging mode. The characteristic bright red emission and superior hydrostability of CaEuCAM under harsh acidic and basic conditions benefit it by acting as a highly sensitive sensor for Fe 3+ and 3nitrophenol (3-NP) with extremely low LODs through remarkable quenching. The combination of experiments and theoretical calculations for sensing mechanisms shows that the competitive absorption and interaction are responsible for Fe 3+ -induced selective emission quenching, while that for 3-NP is the result of the synergism of host−guest chemistry and the inner filter effect. Meanwhile, the assimilation of negative charge plus channels renders CaEuCAM a highly selective adsorbent for methylene blue (MB) due to a synergy of electrostatic affinity, ion-dipole interaction, and size matching. Of note is the reusability of CaEuCAM toward Fe 3+ /3-NP sensing and MB adsorption besides its fast response. These findings could be very useful in guiding the development of multifunctional Ln-MOFs for sensing and adsorption applications in water media.
