“…Based on the signal to noise ratio of 3, the detection limit of 0.1 μM was obtained. The fabricated PANI/ZnO/MWCNT sensor electrode shows better performance and higher sensitivity for the non-enzymatic determination of glucose in comparison to other previously reported non-enzymatic glucose biosensors that focused on carbon nanotubes, ZnO nanoparticles, and PANI nanofibers-modified electrodes [37][38][39]. Such enhanced sensitivity can be attributed to the unique properties of carbon nanotubes, zinc oxide nanoparticles, and polyaniline nanofibers and their synergistic effect which results in a significant improvement of the electrochemical activity of the modified electrode for the detection of glucose.…”

<p class="PaperAbstract">Novel polyaniline/zinc oxide/multi-walled carbon nanotube (PANI/ZnO/MWCNT) ternary nanocomposite was fabricated as a non-enzymatic glucose biosensor. Thermal chemical vapor deposition (CVD) process was employed to synthesize vertically aligned MWCNTs on stainless steel substrates coated by Co catalyst nanoparticles. In order to fabricate sensitive and reliable MWCNT-based biosensors, nanotubes density and alignment were adjusted by varying the CVD reaction time and cobalt sulfate concentration. The fabricated nanotubes were modified by ZnO particles through the potentiostatic electrodeposition technique. Optimal electrodeposition potential, electrodeposition time, and electrolyte concentration values were determined. The optimized ZnO/MWCNT nanocomposite was reinforced by polyaniline (PANI) nanofibers through the potential cycling technique, and the morphology, elemental composition, and phase structure of the fabricated nanocomposites were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD), respectively. The sensing mechanism of the PANI/ZnO/MWCNT electrode for the electrochemical detection of glucose was investigated, and the limit of detection and sensitivity values of the designed sensor were determined. The fast response time of the ternary nanocomposite-based sensor as well as its satisfactory stability and reproducibility, makes it a promising candidate for non-enzymatic detection of glucose in biomedical, environmental, and industrial applications.</p>

“…Recently, transition‐metal dichalcogenides (TMDs) emerged as interesting materials with widespread interest, because of their exceptional electrochemical properties . Traditional‐metal oxides (TMOs) and transition‐metal hydroxides (TMHs) have been extensively investigated for the development of non‐enzymatic glucose sensors. Relative to TMOs and TMHs, TMDs shows high electrical conductivity which can increase the kinetics of electron transport, an essential characteristic for an electrochemical reaction.…”

Abstract:We describe the preparation of NiCo2S4 (NCS) nanosheets on photolithographically patterned platinum electrodes by electrodeposition.The as-prepared nanosheets were systematically characterized by field emission scanning electron microscope (FESEM), energy dispersive X-ray (EDX) and X-ray photoelectron spectroscopy (XPS) techniques. The NCS modified Pt electrode was used as a non-enzymatic glucose sensor. The sensor response exhibited two linear regions in glucose concentration, with a limit of detection of 1.2 μM. The sensors showed that the asprepared NCS nanosheets have excellent electrocatalytic activity towards glucose with long stability, good reproducibility and excellent anti-interference property, thus demonstrating that this material holds promise for the development of a practical glucose sensor.

“…Enzyme-based sensors show good selectivity and high sensitivity, but their activity is affected by temperature, pH, and toxic chemicals [13] , [14] . In order to overcome these drawbacks of enzymatic glucose sensors, non-enzymatic glucose sensors have been designed and fabricated, which have several attractive advantages, such as good stability, selectivity and sensitivity and lower detection limit [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] .…”

In this work, carbon nanosheet (CNS) based electrode was designed for electrochemical biosensing of glucose. CNS has been obtained by the pyrolysis of barley at 600–750 °C in a muffle furnace; it was then purified and functionalized. The CNS has been characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopic techniques. The electrochemical activity of CNS-based electrode was investigated by linear sweep voltammetry (LSV) and square wave voltammetry (SWV), for the oxidation of glucose in 0.001 M H2SO4 (pH 6.0). The linear range of the sensor was found to be 10−4–10−6 M (1–100 µM) within the response time of 4 s. Interestingly, its sensitivity reached as high as ~26.002±0.01 μA/μM cm2. Electrochemical experiments revealed that the proposed electrode offered an excellent electrochemical activity towards the oxidation of glucose and could be applied for the construction of non-enzymatic glucose biosensors.
