“…It is evident from the cyclic voltammograms that quercetin is oxidized at GCE at 478 mV with an anodic peak current of 6.17 µA, and quercetin is detected at Co@MO/GCE at a greater current response of 7.35 µA with a lower peak potential of 342 mV. Karuppusamy et al suggested that the GCE modified with 6 µL of CdTe/BS-RGO/GCE exhibited greater response when tested under 50 µM QR with 0.1 M PB (pH 7.0) at 50 mV [ 27 ]. Muthamizh et al observed that quercetin was oxidized and also exhibited a higher response with a lower peak potential [ 28 ].…”

Background: The pressing need for precise, quick, and affordable detection of diverse biomolecules has led to notable developments in the realm of biosensors. Quercetin, a biomolecule rich in flavonoids predominantly found in our diet, is sensed by the electrochemical method. The electrochemical properties show remarkable improvement when Mn 2 O 3 (MO) is doped with cobalt (Co). Aim: This study aimed to investigate the biomolecule sensing of quercetin using Co-doped MO by electrochemical method. Materials and methods: Co-doped MO nanospheres were prepared by hydrothermal method. The crystal structure of the synthesized material was evaluated by using X-ray diffraction analysis. The sample morphology was assessed by using field emission scanning electron microscopy (FE-SEM) techniques. The cyclic voltammetry technique was used for the detection of quercetin biomolecules. Results: The synthesized Co-doped MO appeared to be spherical in morphology in FE-SEM. Energy-dispersive X-ray spectroscopy showed the only presence of Co, Mn, and O, which confirmed the purity of the sample. The modified electrode sensed the biomolecule with a higher current of 7.35 µA than the bare glassy carbon electrode of 6.1 µA. Conclusion: The Co-doped MO exhibited enhanced conductivity, reactivity, and electrochemical performance. This tailored approach will help in the optimization of material properties toward specific biomolecule sensing applications.

“…To reduce the cost on fabrication the biosensors, other metals with relatively low cost like Cu, Co, Ni have attracted extensive attentions for their combinations with graphene [126d, f, i, 134]. For these metals, the materials with different morphologies have been well developed.…”

“…The studies on fabrication of Cu NPs with different structures (shown in Figure 8a) demonstrated that the dendritic Cu NPs displayed higher electrochemical performance on the glucose sensing over that of Cu NPs with the cubic, spherical and quasidendritic structure [134]. In addition, fabrication bimetallic NPs also have been proposed as an efficient method to enhance the electrochemical performance, as the two metals can provide different kinds of active sites [126c, d, i, 135]. As displayed in Figure 8b, the bimetallic NPs like Cu−Co modified graphene biosensors demonstrated excellent catalytic activity toward the glucose oxidation.…”

Graphene, a honeycomb lattice of carbon material with single‐atom‐layer structure, demonstrates extraordinary mechanical, thermal, chemical and electronic properties. Thus, it has sparked tremendous interests in various fields, such as energy storage and conversion devices, field‐effect transistors (FET), chemical sensors and biosensors. In this review, we will first focus on the synthesis method of graphene and the fabrication strategy of graphene‐based materials. Subsequently, the construction of graphene‐based biosensors are introduced, in which three kinds of biosensors are discussed in details, including the FET, electrochemical biosensors and electrochemiluminescence (ECL) biosensors. The performances of the state‐of‐the‐art biosensors on the detection of biomolecules are also displayed. Finally, we also highlight some critical challenges remain to be solved and the development in this field for further research.

“…Since R ct controlled the electron transfer kinetics of the redox probe at the electrode interface when bare GCE was modified with Au-BSN-rGO (curve a), Au-BSN-rGO had the smallest half-circle diameter, and its charge transfer resistance value is 5.87 Ω, indicating that Au-BSN-rGO had good conductivity. 47 When anti-Aβ 1-42 (curve b), BSA (curve c), and Aβ 1-42 (curve d) were sequentially modified onto the surface of Au-BSN-rGO, their corresponding semicircular diameters sequentially increased as anti-Aβ 1-42, BSA and Aβ 1-42 delayed the electron transfer capability between the electrochemical bilayer and the redox probe, resulting in higher R ct values for the redox probe in the electrochemical bilayer and their corresponding semicircular diameters. The impedance test results were in good agreement with the CV test results, which further confirmed the successful fabrication of the electrochemical immunosensor.…”
