“…The reversible redox conversion of 3-hydroxylamine tyrosine to its nitroso form leads to a superior cathodic current response for the MoS 2 @BiVO 4 /GCE at a lower peak potential of −0.58 V. The small redox peak corresponds to the reversible conversion of 3-hydroxylamine tyrosine to 3-nitroso tyrosine (Scheme 2). 10 Effect of Catalyst Loading Amount. The reaction conditions were refined by experimenting with different quantities of MoS 2 @BiVO 4 nanocomposite used to coat the working electrode surface coverage area.…”

The quantification of 3-nitro-l-tyrosine (NO2-Tyr), an in vivo biomarker of nitrosative stress, is indispensable for the clinical intervention of various inflammatory disorders caused by nitrosative stress. By integrating the unique features of BiVO4 and MoS2 with matching bandgap energies, electrode materials with amplified response signals can be developed. In this regard, we introduce a hydrothermally synthesized bismuth vanadate sheathed molybdenum disulfide (MoS2@BiVO4) heterojunction as a highly sensitive electrode material for the determination of NO2-Tyr. Excellent electrochemical behavior perceived for the MoS2@BiVO4 augments the performance of the sensor and allows the measurement of NO2-Tyr in biological media without any time-consuming pretreatments. The synergistic interactions between BiVO4 and MoS2 heterojunctions contribute to low resistance charge transfer (R ct = 159.13 Ω·cm2), a reduction potential E pc = −0.58 V (vs Ag/AgCl), and a good response range (0.001–526.3 μM) with a lower limit of detection (0.94 nM) toward the detection of NO2-Tyr. An improved active surface area, reduced charge recombination, and high analyte adsorption contribute to the high loading of the biomarker for improved selectivity (in the presence of 10 interfering compounds), operational stability (1000 s), and reproducibility (six various modified electrodes). The proposed sensor was successfully utilized for the real-time determination of NO2-Tyr in water, urine, and saliva samples with good recovery values (±98.94–99.98%), ascertaining the reliability of the method. It is noteworthy that the electrochemical activity remains unaffected by other redox interferons, thus leading to targeted sensing applications.

Amnio acids are essential for body life, and thus, introducing novel simples/sensitive techniques/catalyst for detecting their low levels, especially in real samples and mixtures, is a great issue in analytical/bioanalytical chemistry. Thus, NiO nanoparticles were synthesized and used for the modification of a carbon paste electrode (CPE) for the square wave voltammetric (SqW) determination of tyrosine (Tyr) in the presence of tryptophan (Tryp), phenylalanine (PhA), and cysteine (Cis) amino acids (AA), all having the À CH 2 À CH(NH 2 )À COOH functional group. The calibration sensitivity was increased in interfering AA species which caused the decreased detection (for example, detection limit (DL) 1.32 μM to 0.88 μM Tyr) and quantification limits. For different concentrations of interfering AA species, the linear range (LR) was decreased that was more intense with an increase in AA amount. For example, the LR of 5-1800 μM Tyr in the absence of other AA species was changed to 80-800, 90-850, and 70 À 1000 μM Tyr in the presence of 20 mM Tyr, Csy, and PhA, respectively. A g-value of 0.487 < g 0.05,6,5 = 0.5875 confirmed the long-term stability of the electrode for 4 months. The electrode showed good selectivity towards Tyr in the presence of some amino acids and inorganic salts. Recovery experiments also confirmed the good capability of the electrode in Tyr quantification in a complex matrix such as six human serums used.

This report presents a new application for yttrium oxide (YOX) in the modification of carbon paste electrodes with excellent electroactivity for the independent detection of dopamine (DA) and ascorbic acid (AA). The surface of the YOX‐modified electrode was characterized with SEM and EDS. The electroactive properties of DP and AA were studied with cyclic voltammetry (CV), square wave voltammetry (SWV) and amperometry (Am). The activity of DA and AA increased by more than 100 % when YOX/CPE was used, which allowed us to obtain detection limits of 0.04 and 0.06 μmol/L for DA and AA, respectively. The usefulness of YOX/CPE was tested with real human urine, fresh orange juice and vitamin C tablets, and the results were acceptable.
