“…Except for the instrumental methods, colorimetry has been focused, owing to cheapness, sensitivity, simplicity, convenience (no need for sophisticated instruments), etc. In recent years, many efforts have been motivated for the detection of H 2 O 2 based on peroxidase mimics, including oxides [8], sulfide [9], metal nanoparticles [10], and carbon nanomaterials [11]. In addition, various GSH sensors based on peroxidase mimics have been reported, such as MnO 2 nanosheets [12], Co 3 O 4 nanotubes [13], and dipyrromethene (BODIPY) derivatives [14].…”

In the present study, a facile method was proposed to prepare nickel sulfide (NiS) nanoparticles well-dispersed on the surface of montmorillonite/graphene oxide (MMT/GO). The NiS/MMT/GO nanocomposites were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), fluorescence spectrophotometry, etc. Significantly, the novel NiS/MMT/GO nanocomposites exhibited high peroxidase-like activity toward the typical chromogenic substrate, 3,3′,5,5′-tetramethylbenzidine (TMB). However, glutathione (GSH) could inhibit the peroxidase-like activity of NiS/ MMT/GO along with a visible color variation. Based on the color change of the system of nanocomposites-H 2 O 2 -TMB, a novel colorimetric sensor was designed and conveniently used to quantitatively detect H 2 O 2 as well as GSH. The limit of detection (LOD) of H 2 O 2 and GSH is 9.73 and 0.5043 μM, respectively. The proposed H 2 O 2 sensor has potential application in the field of biosensing, food, and environment.

“…The oxidation of glucose on the CuS/S‐rGO is measured by the Cu(I)/Cu(II) redox couple, based on the following reactions: Cu(I)→Cu(II)+e − and Cu(II)+glucose→Cu(I)+gluconolactone. Radhakrishnan and Kim used NiS‐decorated rGO (NiS‐rGO) as an active material for electrochemical oxidation of glucose. The mechanism of glucose oxidation on the NiS‐rGO can be described as follows: NiS+OH − →NiSOH+e − and NiSOH+glucose→NiS+glucolactone.…”

With the increasing demand for highly sensitive and selective glucose sensors in industrial, clinical and pharmaceutical sectors, sensing materials for glucose detection have attracted much attention worldwide. Due to the large surface area, fascinating physical and electrochemical properties, graphene‐based materials have been widely used as a unique class of promising electrode materials in electrochemical sensing applications, with the continuously growing academic and technological developments. In this review, we summarize the different preparation strategies for the synthesis of graphene‐based materials and the application in electrochemical detection of glucose, including enzymatic and nonenzymatic glucose sensors.
