“…The electrocatalytic performances for our prepared glucose sensors are better than those reported sensors, such as CuS nanotubes (9.9005 μA μmol L −1 , 0.25 μmol L −1 ), ZnS‐NiS nanospheres (26.4 μA mM −1 , 0.125 μM), PtNi nanoparticles/Graphene (20.42 μA mM −1 cm −2 , 0.01 mM) and Cu nanoblets (44.3 μA mM −1 cm −2 , 10 μM) ,. However, some reported non‐enzymatic sensors are better than our glucose sensors, such as rose‐like α‐Ni(OH) 2 (418.8 μA mM −1 cm −2 , 0.08 μM) and NiO/C (149.1 μA mM −1 , 9.12 nM) ,. Based on these results, it can be demonstrated that the as‐prepared hierarchical MnCo 2 S 4 nanotubes are promising sensor materials for detection glucose.…”

Hierarchical MnCo2S4 nanotubes have been successfully prepared via a facile self‐template approach. The as‐prepared hierarchical MnCo2S4 nanotubes are evaluated as electrode materials for supercapacitors, which exhibits a specific capacitance of 705.2 F g−1 at 0.5 A g−1 and a remarkable cycling performance. Moreover, the hierarchical MnCo2S4 nanotubes are also applied in non‐enzymatic glucose sensors, which possesses good electrocatalytic performances with a low determination limit (0.1 μM) and good selectivity. In addition, yolk‐shelled MnCo2O4 prisms were also prepared via the self‐template method. The electrochemical performance of the yolk‐shelled MnCo2O4 prisms were also studied. It is found that the as‐prepared hierarchical MnCo2S4 nanotubes show better electrochemical performances than yolk‐shelled MnCo2O4 in this work.

“…Mapped by X‐ray photoelectron spectroscopy (XPS), a full‐survey‐scan spectrum in Figure d revealed the peaks of elements Ni, O, Au and C. C 1s peak was attributed to the contaminated carbonaceous that accumulated during the storage of the sample from the environment 17b. The typical high‐resolution XPS spectrum of Ni (Figure e) showed two main peaks at 855.9 and 873.5 eV with a 17.6 eV spin‐energy separation, which were attributed to the Ni 2p 3/2 and Ni 2p 1/2 components . Those main peaks were accompanied by the broad peaks located at 861.4 and 879.6 eV, which are the satellite peaks of Ni 2p 3/2 and Ni 2p 1/2 .…”

Simple, low-cost and yet accurate, sensitive, and quantitative detection of a broad range of analytical targets by means of small footprint sensing devices has the potential to revolutionize medical diagnostics, food safety, and environmental monitoring. This work demonstrates a functional nucleic acids (FNAs) tethered AuNPs/β-Ni(OH) 2 nanosheets (NS)/Ni foam nanocomposite as a miniaturized electrode. Through the rational design of a low-barrier ohmic contact of AuNPs to β-Ni(OH) 2 NS and a target mediated nanochannel electron transfer effect, a variety of analytical targets, ranging from a disease marker (thrombin, 16.3 × 10 −12 m detection limit) to an important biological cofactor (adenosine, 3.2 × 10 −12 m detection limit), and to a toxic metal ion (Hg 2+ , 3.1 × 10 −12 m detection limit), are detected with ultrasensitivity. The presence of target triggers the conformational change of FNAs, introducing strong steric hindrance and electrostatic repulsion to the diffusion of electron indicators toward the electrode surface, ultimately leading to the changes in impedance. A novel equivalent circuit considering the capacitive reactance is proposed to describe the 2D NS-based impedance DNA bioelectrode. This sensing platform is easily applicable to the detection of many other targets in diverse sample matrices through the use of other suitable FNAs materials.

“…The selectivity of Ni based electrodes towards glucose determination respect to typical interfering species in alkaline solution, has been widely demonstrated . Figure shows the amperometric response of PF/Ni30 based sensor during successive additions of 1 mM glucose, 0.1 mM ascorbic acid (AA), 0.1 mM uric acid (UA), 0.1 mM dopamine (DA) and again 1 mM glucose in 0.1 M KOH at an applied potential of 0.6 V. This investigation demonstrates that the determination of glucose by the reported sensor is not relevantly affected by these electroactive molecules, therefore it may be suitable for glucose monitoring in real physiological samples.…”

Non‐enzymatic Glucose Sensor Based on Nickel/Carbon Composite

et al. 2018

View full text Add to dashboard Cite

Nickel/carbon composites (Ni−C) have been synthesized by a pyrolysis treatment carried out at the temperature of 675 °C, of NiO incorporated into a pyrogallol‐formaldehyde organic wet gel. Structural and morphological characterizations of the Ni−C samples were performed by XRD and SEM analysis, respectively. Electrochemical non‐enzymatic glucose sensors were fabricated modifying the working electrode surface of screen printed carbon electrodes. Cyclic voltammetry and amperometric tests were performed in order to investigate the electrocatalytic activity of differently Ni loaded carbon towards the oxidation of glucose in alkaline 0.1 M KOH solution. The sensor based on 30 % Ni/carbon showed the best sensing performance towards glucose monitoring with a sensitivity of 670 μA/mM cm−1 in the a liner range from 20 to 500 μM, and a detection limit lower than 8 μM at S/N=3.
