“…Conforme a los datos de literatura [18][19][20][21][22][23][24][25][26], en la mayoría de los casos, la detección electroquímica del ácido úrico se da en medio neutro, o ligeramente alcalino, según el mecanismo: (1) Y esta reacción hace que el sistema conjugado en el producto se establezca sin interrupciones.…”

“…Se han usado varios modificadores de electrodos para la detección del ácido úrico, como los polímeros conductores [18][19][20][21], nanopartículas metálicas y sus compósitos [22][23][24], derivados ferrocénicos [25,26], y el oxihidróxido de cobalto, un semiconductor del tipo p, visto por algunos investigadores como una alternativa al dióxido de titanio [27,28] y usado para detectar las sustancias, cuya oxidación se da en condiciones semejantes [29,30], también puede ser una buena alternativa.…”

289Evaluación teórica del desempeño del electrodo, modificado por el oxihidróxido de cobalto (III) en la detección del ácido úrico Recibido para evaluación: 24 de noviembre de 2016 Aceptado para publicación: 27 de abril de 2018 Resumen La posibilidad del empleo de oxihidróxido de cobalto como modificador del electrodo en la detección del ácido úrico se investigó desde el punto de vista teórico. Se sugiere el mecanismo del desempeño del compuesto inorgánico en el proceso, y el modelo, correspondiente al proceso, se analizó mediante la teoría de estabilidad lineal y análisis de bifurcaciones. Se concluye que el oxihidróxido de cobalto puede servir como un modificador eficiente, facilitando la oxidación del analito en medio neutro en el modo galvanostático. La inestabilidad monotónica para este caso no puede realizarse, y la oscilatoria es causada por el único factor.Palabras clave: ácido úrico, sensores electroquímicos, electrodos químicamente modificados, oxihidróxido de cobalto (III), estado estacionario estable.

SummaryTheoretical evaluation of the work of the electrode, modified by cobalt (III) oxyhydroxide, in the uric acid detectionThe possibility of use of cobalt oxyhydroxide as an electrode modifier in the uric acid determination has been investigated from the theoretical point of view. The mechanism of the use of the inorganic compound in the process has been suggested, and the model, correspondent to the process, has been analyzed by means of linear stability theory and bifurcation analysis. It has been concluded that the cobalt oxyhydroxide may serve as an efficient modifier, making easier the analyte oxidation in neutral media in galvanostatic mode. The monotonic instability for this case isn't capable to realize, and the oscillatory behavior is caused by the unique factor.

A new supramolecular electrochemical sensor for highly sensitive detection of dopamine (DA) was fabricated based on supramolecular assemblies of mixed two surfactants, tetra-butylammonium bromide (TBABr) and sodium dodecyl sulphate (SDS), on the electrodeposition of gold nanoparticles on graphene oxide modified on glassy carbon electrode (AuNPs/GO/GCE). Self-assembled mixed surfactants (TBABr/SDS) were added into the solution to increase the sensitivity for the detection of DA. All electrodes were characterized by scanning electron microscopy (SEM), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The supramolecular electrochemical sensor (TBABr/SDS⋅⋅⋅AuNPs/GO/GCE) showed excellent electrocatalytic activity toward the oxidation of DA. Under the optimum conditions, the concentration of DA was obtained in the range from 0.02 µM to 1.00 µM, with a detection limit of 0.01 µM (3s/b). The results displayed that TBABr/SDS⋅⋅⋅AuNPs/GO/GCE exhibited excellent performance, good sensitivity, and reproducibility. In addition, the proposed supramolecular electrochemical sensor was successfully applied to determine DA in human serum samples with satisfactory recoveries (97.26% to 104.21%).

“…Ni catalyst shows better urea oxidation activity in urea fuel cells than noble metals, such as Pt, Ir, Rh etc. ; although there is a problem due to the degradation of nickel catalysts, suggesting an easily deactivated catalytic surface during urea electro‐oxidation, for this reason, noble metals are incorporated into the nickel catalyst ,. Nickel oxide nanoparticles have high electrocatalytic activity, fast electron transport property, high surface energy, chemical stability, low cost and biocompatibility, meaning it can be used for the oxidation of urea, but in the case of this evaluation the double layered hydroxides presented a better catalytic power for the oxidation of the urea.…”

NiAl Layered Double Hydroxides and PdNiO as Multifunctional Anodes for Prospective Self‐Powered Lab‐on‐a‐Chip Dopamine Sensors

et al. 2018

The purpose of this work is the evaluation of two bimetallic materials, PdNiO and NiAl-layered double hydroxides (NiAl-LDHs) for their prospective use in Lab-on-a-Chip devices, in which urea contained in human urine is used as fuel to provide the energy required by the device and dopamine in the sample is detected. A urea microfluidic fuel cell, using human urine as fuel and NiAl-LDHs and PdNiO as anodes, was constructed and evaluated, resulting in a cell potential of 1 V with 50.19 mW/cm 2 power density for NiAl-LDHs and 0.9 V and 32.94 mW/cm 2 for PdNiO. The multifunctionality of these anodes was extended for detecting dopamine with detection limits of 7.38 10 À8 M and 5.46 10 À6 M for NiAl-LDHs and PdNiO, respectively. The higher content of hydroxides on NiAl-LDHs than PdNiO material allowed a better activity for urea oxidation and dopamine detection. These results show the prospects for self-powered biomedical Lab-on-a-Chip device development.
