Abstract
This study establishes structure-property relationships for four synthetic flavin molecules as bioinspired redox mediators in electro- and photocatalysis applications. The studied flavin compounds were disubstituted with polar substituents at the N1 and N3 positions (alloxazine) or at the N3 and N10 positions (isoalloxazines). The electrochemical behavior of one such synthetic flavin analogue was examined in detail in aqueous solutions of varying pH in the range from 1 to 10. Cyclic voltammetry, used in conjunction with hydrodynamic (rotating disk electrode) voltammetry, showed quasi-reversible behavior consistent with freely diffusing molecules and an overall global 2e(-) , 2H(+) proton-coupled electron transfer scheme. UV/Vis spectroelectrochemical data was also employed to study the pH-dependent electrochemical behavior of this derivative. Substituent effects on the redox behavior were compared and contrasted for all the four compounds, and visualized within a scatter plot framework to afford comparison with prior knowledge on mostly natural flavins in aqueous media. Finally, a preliminary assessment of one of the synthetic flavins was performed of its electrocatalytic activity toward dioxygen reduction as a prelude to further (quantitative) studies of both freely diffusing and tethered molecules on various electrode surfaces.

Abstract
A simple method to immobilize poly(neutral red) (PNR) and flavin adenine dinucleotide (FAD) hybrid film (PNR/FAD) by cyclic voltammetry is proposed. The PNR/FAD hybrid film can be easily prepared on an electrode surface involving electropolymerization of neutral red (NR) monomers and the electrostatic interaction between the positively charged PNR and the negatively charged FAD. It exhibits electroactive, stable, surface-confined, pH-dependent, nano-sized, and compatible properties. It provides good electrocatalytic properties to various species. It shows a sensitivity of 5.4 μA mM(-1) cm(-2) and 21.5 μA mM(-1) cm(-2) for hydrogen peroxide (H(2)O(2)) and nicotinamide adenine dinucleotide (NADH) with the linear range of 0.1 μM-39 mM and 5 × 10(-5) to 2.5 × 10(-4) M, respectively. It shows another linear range of 48.8-355.5 mM with the sensitivity of 12.3 μA mM(-1) cm(-2) for H(2)O(2). In particular, the PNR/FAD hybrid film has potential to replace some hemoproteins to be a cathode of biofuel cells and provide the biosensing system for glucose and ethanol.

Abstract
We report the synthesis and the electrochemical properties of hybrid films made of zinc oxide (ZnO) and Meldola's blue dye (MB) using cyclic voltammetry (CV). MB/ZnO hybrid films were electrochemically deposited onto glassy carbon, gold and indium tin oxide-coated glass (ITO) electrodes at room temperature (25+/-2 degrees C) from the bath solution containing 0.1 M Zn(NO3)2, 0.1 M KNO3 and 1x10(-4) MMB. The surface morphology and deposition kinetics of MB/ZnO hybrid films were studied by means of scanning electron microscopy (SEM), atomic force microscopy (AFM) and electrochemical quartz crystal microbalance (EQCM) techniques, respectively. SEM and AFM images of MB/ZnO hybrid films have revealed that the surfaces are well crystallized, porous and micro structured. MB molecules were immobilized and strongly fixed in a transparent inorganic matrix. MB/ZnO hybrid films modified glassy carbon electrode (MB/ZnO/GC) showed one reversible redox couple centered at formal potential (E0') -0.12 V (pH 6.9). The surface coverage (gamma) of the MB immobilized on ZnO/GC was about 9.86x10(-12) mol cm(-2) and the electron transfer rate constant (ks) was determined to be 38.9 s(-1). The MB/ZnO/GC electrode acted as a sensor and displayed an excellent specific electrocatalytic response to the oxidation of nicotinamide adenine dinucleotide (NADH). The linear response range between 50 and 300 microM NADH concentration at pH 6.9 was observed with a detection limit of 10 microM (S/N=3). The electrode was stable during the time it was used for the full study (about 1 month) without a notable decrease in current. Indeed, dopamine (DA), ascorbic acid (AA), acetaminophen (AP) and uric acid (UA) did not show any interference during the detection of NADH at this modified electrode.

Abstract
Thin films of TiO2 (anatase) nanoparticles are assembled at an electrode surface via a layer-by-layer deposition process employing phytic acid, pyromellitic acid, or flavin adenine dinucleotide (FAD) as molecular binders. With all three types of binders, layers of typically 30 nm thickness are formed each deposition cycle. FAD as an electrochemically active component immobilized at the surface of the TiO2 particles is reduced to FADH2 and reoxidized in a chemically reversible two electron-two proton redox process. Two distinct voltammetric signals are observed for the immobilized FAD redox system associated with (i) hopping of electrons at the TiO2 surface (reversible) and (ii) conduction of electrons through the TiO2 assembly (irreversible). The conduction of electrons through the TiO2 assembly is possible by diffusion over considerable distances as well as through a "spacer" layer of TiO2 phytate. An order of magnitude (upper limit) estimate for the diffusion coefficient of electrons through TiO2 phytate, D(electron) approximately 10(-6) m(2) s(-1), is obtained from voltammetric data. Finally, it is demonstrated that the calcination of TiO2 assemblies causes dramatic changes in the electron transfer kinetics for the immobilized FAD/FADH2 redox system.
