“…Hence, from the perspective of safety and security, the development of simple, handy, and competent methodology to monitor these contaminants is the crucial need of the society [8]. To date, there have been a number of analytical instrumental techniques-such as colorimetric, X-ray, fluorescence emission spectroscopy, inductively coupled plasma spectroscopy, atomic absorption spectroscopy, mass spectroscopy, and chromatography-that have been employed for the detection of p-nitrophenol as well as hydrazine [9][10][11][12].…”

The current work reports the successful synthesis of ethylene glycol functionalized gadolinium oxide nanoparticles (Gd2O3 Nps) as a proficient electrocatalytic material for the detection of hydrazine and p-nitrophenol. A facile hydrothermal approach was used for the controlled growth of Gd2O3 Nps in the presence of ethylene glycol (EG) as a structure-controlling and hydrophilic coating source. The prepared material was characterized by several techniques in order to examine the structural, morphological, optical, photoluminescence, and sensing properties. The thermal stability, resistance toward corrosion, and decreased tendency toward photobleaching made Gd2O3 nanoparticles a good candidate for the electrochemical sensing of p-nitrophenol and hydrazine by using cyclic voltammetric (CV) and amperometric methods at a neutral pH range. The modified electrode possesses a linear range of 1 to 10 µM with a low detection limit of 1.527 and 0.704 µM for p-nitrophenol and hydrazine, respectively. The sensitivity, selectivity, repeatability, recyclability, linear range, detection limit, and applicability in real water samples made Gd2O3 Nps a favorable nanomaterial for the rapid and effectual scrutiny of harmful environmental pollutants.

Here, we reported on a one‐step fabrication of magnetite Fe3O4 nanoparticles/indium tin oxide (ITO) electrode based on the direct growing of Fe3O4 nanoparticles on the ITO surface by using a solvothermal process. The modified electrode was used as electrochemical methotrexate (MTX) biosensor with high sensitivity based on cyclic voltammetry and square wave voltammetry techniques. The results demonstrated a linear relationship between the MTX concentration and its oxidation current peak over a wide range from 10−5 to 10−14 mole/L with a limit of detection of 0.4×10−15 M based on the square wave voltammetry (SWV) technique. In addition, Fe3O4/ITO electrode showed a good capability for measuring very low concentrations of MTX drug dissolved in human serum solution. Also, Fe3O4/ITO electrode was used for detecting MTX in blood serum samples collected from patients after their treatment with MTX. The prepared electrode showed the higher sensitivity that higher than the Viva‐E instrument, which opens the door for developing a cheap, simple and higher sensitive MTX sensor.

“…During last few years, various electrochemical techniques have been reported in the literature where chemically modified electrodes like Au@Pd/CB-DPH/GCE, 18 CoS 2 nanomaterial/IL-graphene/GCE, 19 Cu 3 P@NH 2 -MIL-125(Ti), carbon fiber microelectrodes/rhodium, CeO 2 -ordered mesoporous carbon, CuO nanoarray 20 and rhodium nanoparticle/carbon nanofibers, 21 Pt/SPE, 22 PdNP's, 23 Au/Fe 3 O 4 / GO 24 to arrest the inactive electrochemical behavior of hydrazine with bare electrodes. For example, hydrazine oxidation in aqueous medium is reported at −0.33 V vs SCE using dropping Hg electrode and at +0.3 V vs SCE using Pt electrode.…”

In this work, a miniaturized platform for electrochemical detection of hydrazine, has been developed using droplet paper based three electrode system. Copper oxide cluster (CuO) immobilized on the surface of graphite sheet (Grp@CuO) is used as a working electrode. The developed Grp@CuO showed a surface-confined delayed redox response at an electrode potential (E1/2) −0.24 V vs Ag/AgCl in pH 7 phosphate buffer solution (PBS). The physicochemical characterization of the Grp@CuO revealed the electro deposition of CuO cluster on the surface of graphite sheet. Grp@CuO displayed selective electro-catalytic activity towards the detection of hydrazine in pH 7.0 PBS. A systematic linear increase in the oxidation current is observed in the range of 1 μM to 7 μM at an applied potential of −0.6 to 0.2 V vs Ag/AgCl with an excellent current sensitivity, lower detection limit (0.3482 μM). The fabricated miniaturized droplet-based sensor showed zero interference from other chemicals. Therefore, it is a viable option to be used in detection of hydrazine in real samples. Finally, the prepared platform was harnessed to real water samples for hydrazine detection.
