“…One of the main problems in the realization of efficient amperometric sensors lies in the stability of the anchoring of a similar soluble redox mediator on the electrode surface. Stable chemical bonds can be obtained by using some o-quinone derivatives, mainly consisting of 3,4-dihydroxybenzaldehyde [4], caffeic acid (CFA; see Figure 1) [5,6] or chlorogenic acid [7]. They all undergo reversible charge transfer processes, according to the mechanism described in Figure 1 for the case of CFA.…”

Screen-printed electrode (SPE) modified with carbon black nanoparticles (CB) has been tested as a new platform for the stable deposition of caffeic acid (CFA) on the electrode surface. The electrochemical performance from varying the amount of CFA/CB composite has been tested with respect to NADH determination. The electrocatalytic activity of CFA/CB has also been compared with that of SPEs modified by a single component of the coating, i.e., either CFA or CB. Finally, glycerol dehydrogenase, a typical NADH-dependent enzyme, was deposited on the CFA/CB coating in order to test the applicability of the sensor in glycerol determination.

In this study, the composite material that made up polyglycine/3d-4f hybrid-metallic cyano-bridged mixed coordination polymers (CyMCP) was successfully decorated onto a glassy carbon rotating disk electrode (GC RDE) using electrodeposition. The voltammetric behavior of NADH showed typical direct electrooxidation characteristics on the modified GC electrode. Our polyglycine/CyMCP-modified GC RDE was able to measure the apparent heterogeneous electron transfer rate constant of NADH during its direct electrooxidation by preventing fouling effects on the working electrode, which would generally cause a decrease in the oxidative peak current of NADH. In addition, differential pulse voltammetry provided a large linear range between the oxidative peak current and the concentration of NADH from 2-1500 μM at the polyglycine/CyMCP/GC electrode. Finally, the apparent heterogeneous electron transfer rate constant (k s NADH ) of NADH was determined to be 1.73 × 10 −2 cm · s −1 using the polyglycine/CyMCP-modified GC RDE. Both reduced and oxidized forms of β-nicotinamide adenine dinucleotide (NADH and NAD + , respectively) are the coenzymes for a large number of dehydrogenase enzymes (>300) and components of biomarker systems.1 In fact, because of its very important role in the field of analytical electrochemistry, 2,3 bioelectrocatalysis 4-6 and biofuel cells, 7,8 the electrochemical investigation for the formal potential of NADH/NAD + redox couple has attracted much attention. 9,10Therefore, direct oxidation of NADH at untreated or unmodified classical solid electrodes is known to appear poor reversibility and occurs with considerable overpotential (e.g., 1.1 V on carbon and 1.3 V on platinum). [11][12][13][14][15][16] Furthermore, accumulation of oxidation products involving radical intermediates, such as dimer from the one-electron oxidation product NAD +. , 17,18 can cause deactivation and fouling of the electrode surface. Such contamination of the working electrode can largely lower the sensitivity and reproducibility of voltammetric measurements. Consequently, considerable effort has been devoted with a strategy of surface modification on the substrate of conventional materials electrode to attain the electrode's long term stability for determination of NADH at a lower potential. 2,[19][20][21] Over the last few decades, various carbon nanomaterial 22-24 and redox-active mediator materials [25][26][27][28][29][30][31][32][33][34][35] have been modified onto the electrode surface in order to alleviate and/or prevent higher overpotential and fouling problems of the electrode. Therefore, there exist two kinds of catalytic model for the electrooxidation of NADH: one is a direct electro-catalysis 13,15,16,36 and the other is called a redox mediator electro-catalysis. [25][26][27][28][29][30][31][32]37 Though these redox mediators are very efficient electron shuttles for NADH oxidation processes, hydrodynamic voltammetry on the mediator-modified electrode remains a challenge for examining the kinetic parameters of NADH elect...

Voltammetric Detection of NADH Free from Interference of Ascorbic Acid Using a Glassy Carbon Electrode Modified with an Electropolymerized Porphyrin Film

Two square‐wave voltammetric (SWV) peaks, at potentials of ca. 0 and 500 mV (vs. Ag/AgCl) are observed at a porphyrin polymer modified glassy carbon (GC) electrode in Tris buffer solution (pH 8.3), that correspond to the electrooxidation of ascorbic acid (AA) and NADH, respectively. Additionally the proposed electrode is free of fouling problems, that are notorious at other modified electrodes. An interesting observation was that the peak associated with the AA electrooxidation was attenuated as the concentration of NADH increased, indicating a competition in the electron transfer reaction between the two analytes studied. The NADH peak current was directly related to its concentration below 5 mM with a proportionality constant of 92 µA cm−2 mM and with the detection limit of 0.5 µM.
