“…A comparison between similar research is represented in Table 1 , in terms of sensitivity, linear dynamic range and detection limit [ 64 , 65 ]. It observes that the fabricated sensor probe is selective towards target CA in enzyme-less sensing with low-dimensional nano-formulated ternary CMNO NMs by using electrochemical methods, which related other reports in enzyme-less CA detection with different sensing matrixes such as nanomaterials or nanocomposites [ 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 ].…”

The facile wet-chemical technique was used to prepare the low-dimensional nano-formulated porous mixed metal oxide nanomaterials (CuO.Mn2O3.NiO; CMNO NMs) in an alkaline medium at low temperature. Detailed structural, morphological, crystalline, and functional characterization of CMNO NMs were performed by X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-vis), Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), and energy-dispersive X-ray spectroscopy (EDS) analyses. An efficient and selective creatine (CA) sensor probe was fabricated by using CMNO NMs decorated onto glassy carbon electrode (GCE) as CMNO NMs/GCE by using Nafion adhesive (5% suspension in ethanol). The relation of current versus the concentration of CA was plotted to draw a calibration curve of the CMNO NMs/GCE sensor probe, which was found to have a very linear value (r2 = 0.9995) over a large dynamic range (LDR: 0.1 nM~0.1 mM) for selective CA detection. The slope of LDR by considering the active surface area of GCE (0.0316 cm2) was applied to estimate the sensor sensitivity (14.6308 µAµM−1 cm−2). Moreover, the detection limit (21.63 ± 0.05 pM) of CMNO MNs modified GCE was calculated from the signal/noise (S/N) ratio at 3. As a CA sensor probe, it exhibited long-term stability, good reproducibility, and fast response time in the detection of CA by electrochemical approach. Therefore, this research technique is introduced as a promising platform to develop an efficient sensor probe for cancer metabolic biomarker by using nano-formulated mixed metal oxides for biochemical as well as biomedical research for the safety of health care fields.

“…4(b) exhibits a pattern to increase the I-V intensity with the increasing concentration of 4-NPHyd from lower to higher. This patter has described by previous authors in the detection of toxic chemicals in earlier [52][53][54][55][56][57] NPs. It happens due to the combinational effects of both metal oxides.…”

The 4-NPHyd (4-nitrophenylhydrazine) electrochemical sensor assembled using wet-chemically prepared ZnO/SnO2 nanoparticle (NPs) decorated a glassy carbon electrode (GCE) with conductive Nafion binder. The synthesized NPs characterized by XPS, ESEM, EDS, and XRD analysis. The calibration of the proposed sensor obtained from current versus concentration of 4-NPHyd found linear over a concentration (0.1nM~0.01mM) of 4-NPHyd, which denoted as the dynamic range (LDR) for detection of 4-NPHyd. The 4-NPHyd sensor sensitivity calculated using the LDR slope considering the active surface of GCE (0.0316 cm2), which is equal to be 7.6930 µAµM-1cm-2, an appreciable value. The detection limit (LOD) at signal/noise (S/N=3) estimated, and outstanding lower value at 94.63±4.73 pM perceived. The analytical parameters such as reproducibility, long-term performing ability and response time are found as appreciable. Finally, the projected sensor shows exceptional performances in the detection of 4-NPHyd in environmental samples.

“…As binding agent, it was used the 5% nafion suspended in the ethanol, which was enhanced the binding strength between GCE and CdSe/ZnS QDs. Thus, the applied nafion was improved the binding strength in addition to increase the electron transport rate of the proposed electro-chemical sensor [72][73][74][75][76][77] . To test the proposed selectivity of chemical sensor, the number of environmental contaminants with the concentration of 0.1 µM and applied potential ranging from 0 to +1.5 V were investigated in phosphate buffer solution at neutral pH.…”

Quantum dots (QDs) are semiconducting inorganic nanoparticles, tiny molecules of 2-10 nm sizes to strength the quantum confinements of electrons. The QDs are good enough to emit light onto electrons for exciting and returning to the ground state. Here, CdSe/ZnS core/shell QDs have been prepared and applied for electrochemical sensor development in this approach. Flat glassy carbon electrode (GCE) was coated with CdSe/ZnS QDs as very thin uniform layer to result of the selective and efficient sensor of 3-CP (3-chlorophenol). The significant analytical parameters were calculated from the calibration plot such as sensitivity (3.6392 µA µM −1 cm −2) and detection limit (26.09 ± 1.30 pM) with CdSe/ZnS/ GCE sensor probe by electrochemical approach. The calibration curve was fitted with the regression coefficient r 2 = 0.9906 in the range of 0.1 nM ∼ 0.1 mM concentration, which denoted as linear dynamic range (LDR). Besides these, it was performed the reproducibility in short response time and successfully validated the fabricated sensor for 3-CP in the real environmental and extracted samples. It is introduced as a noble route to detect the environmental phenolic contaminants using CdSe/ZnS QDs modified sensor by electrochemical method for the safety of healthcare and environmental fields at broad scales. Semiconductor quantum dots (QDs), in particular those of cadmium chalcogenides (CdS, CdSe, CdTe), have received steadily growing attention due to their high potential for various applications, such as sensing 1,2 , biological labeling 3-12 , light-emitting devices (LED) 13-17 , lasers 18,19 , and solar cells 20-22. Recently, the number of interest has been developed in the area of electrochemical sensors and biosensors in which CdSe are employed for the determination of clinical markers 23 and food 24 and environmental pollutants 25,26. CdSe have been using as electrochemical signal tracers to exploit the oxidation potentials of the metal ions forming them. This can also be attributed to some of the characteristics of CdSe, such as a large surface area-to-volume ratio, good interfacial properties with high surface reaction activity, high electron-transfer efficiency, excellent biocompatibility, and feasibility for surface modification 27-30. Moreover, metallic QDs also constitute a feasible option for electrochemical multiplexed assays due to their different stripping peak potentials 31,32. This is particularly true for the development of efficient, reliable, rapid, and cost-affordable analytical procedures for the determination of anthropogenic and natural substances of either organic or mineral nature that have toxic, persistent, and bio-accumulative properties. Due to the prevalent pollution of ground and surface water by chloro-organic chemicals such as chlorophenol derivatives, the public concern has been growing over the several few decades. Because, the chlorophenols (including 3-CP) have high toxicity and able to produce mutagenic, estrogenic and carcinogenic effects in human beings 33-36 and even unsafe for t...
