“…Figure 2 shows the EDXS spectrum of the MoS 2 /ZnO nanocomposite sample and confirms the presence of Mo, S, O, and Zn without any other impurities from the source ingredients. The HR-TEM images and analysis provided strong evidence for the formation of flower-structured MoS 2 with a nano sheet-like structure, while the MoS 2 /ZnO nanocomposite was confirmed to contain Mo, S, O, and Zn without any other impurities through EDXS spectrum analysis [ 39 ].…”

In order to support biomolecule attachment, an effective electrochemical transducer matrix for biosensing devices needs to have many specialized properties, including quick electron transfer, stability, high surface area, biocompatibility, and the presence of particular functional groups. Enzyme-linked immunosorbent assays, gel electrophoresis, mass spectrometry, fluorescence spectroscopy, and surface-enhanced Raman spectroscopy are common techniques used to assess biomarkers. Even though these techniques provide precise and trustworthy results, they cannot replace clinical applications because of factors such as detection time, sample amount, sensitivity, equipment expense, and the need for highly skilled individuals. For the very sensitive and targeted electrochemical detection of the salivary oral cancer biomarker IL8, we have created a flower-structured molybdenum disulfide-decorated zinc oxide composite on GCE (interleu-kin-8). This immunosensor shows very fast detection; the limit of detection (LOD) for interleukin-8 (IL8) detection in a 0.1 M phosphate buffer solution (PBS) was discovered to be 11.6 fM, while the MoS2/ZnO nanocomposite modified glassy carbon electrode (GCE) demonstrated a high catalytic current linearly from 500 pg to 4500 pg mL−1 interleukin-8 (IL8). Therefore, the proposed biosensor exhibits excellent stability, high accuracy sensitivity, repeatability, and reproducibility and shows the acceptable fabrication of the electrochemical biosensors to detect the ACh in real sample analysis.

“…The diffraction peaks at 16.5°, 32.8° and 57.2° correspond to the (002), (100) and (110) reflection planes of MoS 2 . 44 For COF-Ph, the significant peak at 17.5° was assigned to the reflection (200) plane. Moreover, there were two broad diffraction peaks at 24.8° and 25.2°, which were from the (001) facet of COF-Ph.…”

“…This excellent removal efficiency was likely due to the petal structure of MoS 2 NFs (obtained from SEM and TEM results), which prevented coagulation and resulted in less flexibility of contaminant molecules on the surfaces. 74 Therefore, this petal-like morphology favored the high removal of contaminants. The BET analysis, which revealed a high surface area and monolayer formation (from type IV isotherm), also contributed to this higher removal rate by MoS 2 NFs.…”

“…Without any major loss, the MoS 2 NFs showed a comparable removal capability with recyclability for up to 4 cycles. This was probably due to the flower-like morphology of MoS 2 , which exposed sufficient nanopetal intercalations on the surface and greatly enhanced the active sites on the edges, 74 as well as the involvement of physisorption in the removal process, which made retrieval of MoS 2 NFs much easier than involvement of chemisorption. This flower-like morphology of MoS 2 was considered best for the degradation of dyes 74 and was in line with the SEM-EDS analysis for the spent MoS 2 NF (Supporting Information S7).…”

Two-dimensional (2D) nanomaterial-MoS 2 (molybdenum disulfide) has gained interest among researchers, owing to its exceptional mechanical, biological, and physiochemical properties. This paper reports on the removal of organic dyes and an emerging contaminant, Ciprofloxacin, by a 2D MoS 2 nanoflower as an adsorbent. The material was prepared by a green hydrothermal technique, and its high Brunauer-Emmett-Teller-specific area of 185.541m 2 /g contributed to the removal of 96% rhodamine-B dye and 85% Ciprofloxacin. Various characterizations, such as X-ray diffraction, scanning electron microscopy linked with energydispersive spectroscopy, and transmission electron microscopy, revealed the nanoflower structure with good crystallinity. The feasibility and efficacy of 2D MoS 2 nanoflower as a promising adsorbent candidate for the removal of emerging pollutants was confirmed in-depth in batch investigations, such as the effects of adsorption time, MoS 2 dosages, solution pH, and temperature. The adsorption mechanism was further investigated based on thermodynamic calculations, adsorption kinetics, and isotherm modeling. The results confirmed the exothermic nature of the enthalpy-driven adsorption as well as the fast kinetics and physisorptioncontrolled adsorption process. The recyclability potential of 2D MoS 2 exceeds four regeneration recycles. MoS 2 nanoflower has been shown to be an effective organic pollutant removal adsorbent in water treatment.
