“…Remarkably, it was displayed that there was a clear reduction in faradaic-current response of MoS 2 -GCE modified substrate owing to remarkable reduction in R ct value (17.29 Ω), revealed effective immobilization of MoS 2 at GCE surface ( Figure 2 A; curve b). After functionalization of GCE by MoS 2 -GCE, the R ct value of modified sensing interface there is appearance of rapid heterogeneous faster electron transfer kinetics, 32 which is mainly attributed to its high surface conductivity and higher charge/discharge capacitance of deposited MoS 2 . The enhanced catalytic performance can be attributed to many causes, including the abundance of edge sites that expose S edge atoms and the significant degree of exfoliation, which results in a decreased number of layers.…”

The growing requirement for real-time monitoring of health factors such as heart rate, temperature, and blood glucose levels has resulted in an increase in demand for electrochemical sensors. This study focuses on enzyme-free glucose sensors based on 2D-MoS 2 nanostructures explored by simple hydrothermal route. The 2D-MoS 2 nanostructures were characterized by powder X-ray diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and XPS techniques and were immobilized at GCE to obtain MoS 2 −GCE interface. The fabricated interface was characterized by electrochemical impedance spectroscopy which shows less charge transfer resistance and demonstrated superior electrocatalytic properties of the modified surface. The sensing interface was applied for the detection of glucose using amperometry. The MoS 2 −GCE-sensing interface responded effectively as a nonenzymatic glucose sensor (NEGS) over a linearity range of 0.01−0.20 μM with a very low detection limit of 22.08 ng mL −1 . This study demonstrates an easy method for developing a MoS 2 -GCE interface, providing a potential option for the construction of flexible and disposable nonenzymatic glucose sensors (NEGS). Moreover, the fabricated MoS 2 −GCE electrode precisely detected glucose molecules in real blood serum and urine samples of diabetic and nondiabetic persons. These findings suggest that 2D-MoS 2 nanostructured materials show considerable promise as a possible option for hyperglycemia detection and therapy. Furthermore, the development of NEGS might create new prospects in the glucometer industry.

“…In ECL research, luminol, tris(2,2′-bipyridyl)ruthenium(II) [Ru(bpy) 3 2+ ], quantum dots, and so forth are commonly used ECL emitters in ECL. Among them, Ru(bpy) 3 2+ can be used as the most classical ECL light-emitting carrier due to its low excited state, high ECL quantum yield, and reversible electrochemical behavior .…”

In this work, we propose a novel double-quenching electrochemical luminescence (ECL) strategy; this strategy is based on the double-quenching effect of Ru(bpy)3 2+-functionalized three-dimensional (3D) metal–organic framework (MOF) by MnO2/PDA. An ECL immunosensor for ultrasensitive detection of alpha-fetoprotein (AFP) has been designed. TMU-3 with a rich mesoporous structure can be used to encapsulate Ru(bpy)3 2+, which can effectively reduce the leakage of Ru(bpy)3 2+. Moreover, the ultraviolet–visible (UV–vis) absorption spectrum of the lamellar MnO2/PDA nanomaterials with a nanometer scale of about 1 μm overlaps with the ECL emission spectrum of the porous bamboo leaf-like Ru(bpy)3 2+@TMU-3 with a nanometer scale of about 1 μm. Thus, an ECL resonance energy transfer (ECL-RET) mechanism between Ru(bpy)3 2+@TMU-3 (donor) and MnO2/PDA (recipient) is formed. In this way, an ECL immunosensor with a dual-quenching strategy for ECL signal is developed. In order to test the practicability of this method in clinical analysis, the detection target marker AFP content ranged from 0.01 pg/mL to 5 ng/mL and the detection limit was set to 10.7 fg/mL. In summary, this work demonstrates the detection and application of a signal-quenched ECL immunosensor and ECL immunoassay based on a luminescence-functionalized MOF system for biomarker detection. It indicates a great prospect in the analysis of other biomarkers and clinical analysis.
