Abstract
Redox enzymes can work as efficient electrocatalysts. The coupling of redox enzymatic reactions with electrode reactions is called enzymatic bioelectrocatalysis, which imparts high reaction specificity to electrode reactions with nonspecific characteristics. The key factors required for bioelectrocatalysis are hydride ion/electron transfer characteristics and low specificity for either substrate in redox enzymes. Several theoretical features of steady-state responses are introduced to understand bioelectrocatalysis and to extend the performance of bioelectrocatalytic systems. Applications of the coupling concept to bioelectrochemical devices are also summarized with emphasis on the achievements recorded in the research group of the author.

Abstract
The commonly required properties of diffusive electron mediators for point-of-care testing are rapid dissolubility, high stability, and moderate formal potential in aqueous solutions. Inspired by nature, various quinone-containing electron mediators have been developed; however, satisfying all these requirements remains a challenge. Herein, a strategic design toward quinones incorporating sulfonated thioether and nitrogen-containing heteroarene moieties as solubilizing, stabilizing, and formal potential-modulating groups is reported. A systematic investigation reveals that di(thioether sulfonate)-substituted quinoline-1,4-dione (QLS) and quinoxaline-1,4-dione (QXS) display water solubilities of ≈1 m and are rapidly dissoluble. By finely balancing the electron-donating effect of the thioethers and the electron-withdrawing effect of the nitrogen atom, formal potentials suitable for electrochemical biosensors are achieved with QLS and QXS (-0.15 and -0.09 V vs Ag/AgCl, respectively, at pH 7.4). QLS is stable for >1 d in PBS (pH 7.4) and for 1 h in tris buffer (pH 9.0), which is sufficient for point-of-care testing. Furthermore, QLS, with its high electron mediation ability, is successfully used in biosensors for sensitive detection of glucose and parathyroid hormone, demonstrating detection limits of ≈0.3 × 10-3 m and ≈2 pg mL-1 , respectively. This strategy produces organic electron mediators exhibiting rapid dissolution and high stability, and will find broad application beyond quinone-based biosensors.

Abstract
Bienzymatic systems are often used with electrochemical affinity biosensors to achieve high signal levels and/or low background levels. It is important to select two enzymes whose reactions do not exhibit mutual interference but have similar optimal conditions. Here, we report a sensitive electrochemical immunosensor based on a bienzymatic system consisting of β-galactosidase (Gal, a hydrolase enzyme) and flavin adenine dinucleotide-dependent glucose dehydrogenase (FAD-GDH, a redox enzyme). Both enzymes showed high activities at neutral pH, the reactions catalyzed by them did not exhibit mutual interference, and the electrochemical-enzymatic redox cycling based on FAD-GDH coupled with enzymatic amplification by Gal enabled high signal amplification. Among the three amino-hydroxy-naphthalenes and 4-aminophenol (potential Gal products), 4-amino-1-naphthol showed the highest signal amplification. Glucose, as an electro-inactive, stable reducing agent for redox cycling, helped in achieving low background levels. Our bienzymatic system could detect parathyroid hormone at a detection limit of ∼0.2 pg mL-1, implying that it can be used for highly sensitive electrochemical detection of parathyroid hormone and other biomarkers in human serum.

Abstract
Enzymatically induced silver deposition and subsequent electrochemical oxidation have been widely used in electrochemical biosensors. However, this method is ineffective for producing highly enhanced silver deposition for use in ultrasensitive detection. Herein, we report a fast silver deposition method that simultaneously uses three signal amplification processes: (i) enzymatic amplification, (ii) chemical-chemical (CC) redox cycling, and (iii) chemical-enzymatic (CN) redox cycling. DT-diaphorase (DT-D) is used for enzymatic amplification to convert a nitroso compound, a species incapable of directly reducing Ag+ to an amine compound, which can directly reduce Ag+. NADH acts as a reducing agent for the indirect reduction of Ag+ via the two redox cycling processes. 4-Nitroso-1-naphthol is converted to 4-amino-1-naphthol (NH2-N) in the presence of DT-D. NH2-N initiates two redox cycling processes: NH2-N, along with Ag+ and NADH, are involved in the CC redox cycling, whereas NH2-N, along with Ag+, DT-D, and NADH, are involved in the CN redox cycling. Finally, the deposited silver is electrochemically oxidized to produce a signal. When this triple signal amplification strategy for fast silver deposition is applied to an electrochemical immunosensor for detecting parathyroid hormone (PTH), a detection limit as low as ∼100 fg/mL is obtained. The concentrations of PTH in clinical serum determined using the developed immunosensor are found to agree with those measured using a commercial instrument. Thus, the use of this strategy for fast silver deposition is highly promising for ultrasensitive electrochemical detection and biosensing applications.

Abstract
The most common enzyme labels in enzyme-linked immunosorbent assays are alkaline phosphatase and horseradish peroxidase, which, however, have some limitations for use in electrochemical immunosensors. This Article reports that the small and thermostable DT-diaphorase (DT-D) and electrochemically inactive 4-nitroso-1-naphthol (4-NO-1-N) can be used as a bifunctional enzyme label and a rapidly reacting substrate, respectively, for electrochemical immunosensors. This enzyme-substrate combination allows high signal amplification via rapid enzymatic amplification and electrochemical redox cycling. DT-D can convert an electrochemically inactive nitroso or nitro compound into an electrochemically active amine compound, which can then be involved in electrochemical-chemical (EC) and electrochemical-enzymatic (EN) redox cycling. Six nitroso and nitro compounds are tested in terms of signal-to-background ratio. Among them, 4-NO-1-N exhibits the highest signal-to-background ratio. The electrochemical immunosensor using DT-D and 4-NO-1-N detects parathyroid hormone (PTH) in phosphate-buffered saline containing bovine serum albumin over a wide range of concentrations with a low detection limit of 2 pg/mL. When the PTH concentration in clinical serum samples is measured using the developed immunosensor, the calculated concentrations are in good agreement with the concentrations obtained using a commercial instrument. Thus, the use of DT-D as an enzyme label is highly promising for sensitive electrochemical detection and point-of-care testing.

Abstract
The effects of the cationic polymer ε-poly-L-lysine (εPL) on the enzymatic reaction rate of glucose oxidase (GOD) with ferrocene derivatives having different ionic charges have been investigated by measuring the ferrocene derivative-mediated catalytic current of oxidation by GOD. When negatively charged ferrocenes were used, the bioelectrocatalytic current, which is related to the enzymatic reaction rate, was increased by the addition of εPL. On the other hand, the reaction rates with positively charged ferrocenes were decreased by εPL. These promotion and suppression effects of εPL were remarkable at a certain pH range, where εPL and GOD were charged positively and negatively, respectively. Within this range, the polycationic εPL would be adsorbed onto the GOD surface to enhance the electrostatic interactions of the enzyme with negatively charged substrates, and repulsion with positively charged ones. These findings should be important for practical applications of enzymes.

Abstract
This review describes the input of sol-gel chemistry to the immobilization of polyol dehydrogenases on electrodes, for applications in bioelectrocatalysis. The polyol dehydrogenases are described and their application for biosensing, biofuel cell and electrosynthesis are briefly discussed. The immobilization of proteins via sol-gel approaches is described, including a discussion on the difficulty to maintain the activity of proteins in a silica matrix and the strategies developed to offer a proper environment to the proteins by developing optimal organic-inorganic hybrid materials. Finally, the co-immobilization of the NAD
+
co-factor and of mediators for the elaboration of reagentless devices is presented, based on published and original data. All-in-all, sol-gel approaches appear to be a very promising for development of original electrochemical applications involving dehydrogenases in near future.

Abstract
A new strategy directed to the durable immobilization of NAD(+)/NADH cofactors has been tested, along with a suitable redox mediator (ferrocene), in biocompatible sol-gel matrices encapsulating a bi-enzymatic system (a dehydrogenase and a diaphorase, this latter being useful to the safe regeneration of the cofactor), which were deposited as thin films onto glassy carbon electrode surfaces. It involves the chemical attachment of NAD(+) to the silica matrix using glycidoxypropylsilane in the course of the sol-gel process (in smooth chemical conditions). This approach based on chemical bonding of the cofactor (which was checked by infrared spectroscopy) led to good performances in terms of long-term stability of the electrochemical response. The possibility to integrate all components (proteins, cofactor, mediator) in the sol-gel layer in an active and durable form gave rise to reagentless devices with extended operational stability (i.e. high amperometric response maintained for more than 12h of continuous use under constant potential, whereas the signal completely vanished within the first few minutes of working with non-covalently bonded NAD(+)). To confirm the wide applicability of the proposed approach, the same strategy has been applied to the elaboration of biosensors for D-sorbitol, D-glucose and L-lactate with using D-sorbitol dehydrogenase, D-glucose dehydrogenase and L-lactate dehydrogenase respectively. The analytical characteristics of the glucose sensors are given and compared to previous approaches described in the literature for the elaboration of reagentless biosensors.

Abstract
The ECRG4 gene was initially identified and cloned in our laboratory from human normal esophageal epithelium (GenBank accession no. AF325503). We revealed the expression of ECRG4 protein was downregulated in 68.5% (89/130) ESCC samples using tissue microarray. The low ECRG4 protein expression was significantly associated with regional lymph node metastasis, primary tumor size, and tumor stage in ESCC (p < 0.05). ECRG4 mRNA expression was downregulated in ESCC due to the hypermethylation in the gene promoter. The treatment with 5-aza-2'-deoxycytidine, which is a DNA methyltransferase inhibitor restored ECRG4 mRNA expression in ESCC cells. The result indicated that promoter hypermethylation may be 1 main mechanism leading to the silencing of ECRG4. The high expression of ECRG4 in patients with ESCC was associated with longer survival compared with those with low ECRG4 expression by Kaplan-Meier survival analysis (p < 0.05). ECRG4 protein was an independent prognostic factor for ESCC by multivariable Cox proportional hazards regression analysis (p < 0.05). The restoration of ECRG4 expression in ESCC cells inhibited cell proliferation, colony formation, anchorage-independent growth, cell cycle progression and tumor growth in vivo (p < 0.05). The transfection of ECRG4 gene in ESCC cells inhibited the expression of NF-kappaB and nuclear translocation, in addition to the expression of COX-2, a NF-kappaB target gene, was attenuated. Taken together, ECRG4 is a novel candidate tumor suppressor gene in ESCC, and ECRG4 protein is a candidate prognostic marker for ESCC.

Abstract
Several redox enzymes were examined for enzymatic/electrochemical-recycling systems in order to measure p-aminophenol (PAP) with high sensitivity. Glucose oxidase (GOD) and diaphorase (DI) worked well as catalysts for recycling electrode systems: these enzymes effectively reduced p-iminoquinone (PIQ), the electrochemically-oxidized form of PAP, and caused an enhancement in the electrochemical signals (anodic currents in the voltammogram and amperogram) by approximately 100 fold. The lower detection limits for PAP were estimated to be 50 nM with the GOD system and 2 nM with the DI system. We combined the enzymatic-recycling electrode using DI with an enzyme immunoassay system to measure atrial natriuretic peptide (ANP), an important marker peptide hormone involved in heart diseases. ANPs from serum samples at ppt-levels were determined appropriately using the present assay system.

Abstract
In the class of NADH:acceptor oxidoreductases, the diaphorase from Bacillus stearothermophilusis a particularly promising enzyme for sensing NADH, and indirectly a great number of analytes, when coupled with a NAD-dependent dehydrogenase as well as for the design of mono- and multienzyme affinity sensors. The design and rational optimization of such systems require devising immobilization procedures that prevent dramatic losses of the enzymatic activity and a full kinetic characterization of the immobilized enzyme system. Two immobilization procedures are described, which involve recognition of the biotinylated diaphorase by a monolayer of neutravidin adsorbed on the electrode surface either directly or through the intermediacy of a monolayer of biotinylated rabbit immunoglobulin. Thorough kinetic characterization of the two systems is derived from cyclic voltammetric responses. A precise estimate of the enzyme coverages is obtained after comparing the enzyme kinetics of the immobilized and the homogeneous system.

Abstract
Cyclic voltammetry was successfully applied to study the oxidation of nicotinamide adenine dinucleotide (NADH) both in homogeneous and heterogeneous phase. The first case was realized with a solution containing p-methylamino-phenolsulphate (MAP) as redox mediator and the diaphorase (DI) from Clostridium kluveri as enzyme while the second one by using both a glassy carbon (GC) and a carbon nanotube paste (CNTP) electrode modified with electrodeposited films derived from 3,4-dihydroxybenzaldehyde (3,4-DHB). Such systems were successively coupled with glucose dehydrogenase (GDH) reaction to realize the redox chain present in glucose biosensors. A critical comparison of the two systems was also reported.

Abstract
Cyclic voltammetry has been successfully used to study the oxidation of nicotinamide adenine dinucleotide (NADH) at single-wall carbon-nanotube-paste (CNTP) electrodes modified with p-methylaminophenolsulfate (p-MAP) and 3,4-dihydroxybenzaldehyde (3,4-DHB). Diffusion-like behaviour was observed for p-MAP-modified electrodes, and a diffusion coefficient of 2.4x10(-6) cm2 s(-1) was calculated for p-MAP in the paste. The behaviour of 3,4-DHB-modified CNTP electrodes was typical of that of surface-confined mediators. p-MAP electrocatalytic activity was first checked in solution, and a rate constant of 9.2 mol(-1) L s(-1) was obtained for the reaction between NADH and the mediator. The p-MAP-modified electrode did not have significant electrocatalytic activity for electro-oxidation of NADH, probably because of the formation of a complex between NADH and the confined mediator. In contrast, the 3,4-DHB-modified electrode had very good NADH electrocatalytic activity, with a heterogeneous rate constant of approximately 20x10(2) mol(-1) L s(-1).

Abstract
The electrochemical behavior of riboflavin (RF) adsorbed on different surfaces of inorganic matrices was investigated using modified carbon paste electrodes. Silica gel and sol-gel silica modified with niobium oxide were denominated as (SN) and (SN(sol-gel)), respectively. These materials were treated with a H3PO4 solution to graft phosphate groups and were denominated as (SNP) and (SNP(sol-gel)). The immobilization of RF on these materials indicated a high electrode stability, avoiding leaching out of the electroactive species (RF) from the electrode surface. The values of formal potential (E0') of the adsorbed RF on the different matrices changed from -283 (SNRF) up to -165 mV (SNPRF(sol-gel)) vs SCE in 0.1 moll(-1) NaNO3 solution at pH 7.0. Compared to the E0' for soluble RF, the values are shifted 183 up to 305 mV toward more positive potentials. The stability of the electrodes and the formal potential of the adsorbed RF on different matrices remained constant upon changing the solution pH from 3 to 8. Some kinetic parameters were estimated; indicating that all systems studied presented a good electron transfer rate.

Abstract
This study proposes a novel chemiluminescent assay of bacterial activity. Luminol chemiluminescence (LC) was amplified on addition of menadione to Escherichia coli suspension, and it was effectively inhibited by addition of superoxide dismutase rather than catalase. This fact suggests that H2O2 produced from O2 by superoxide dismutase is decomposed by catalase of E. coli. NAD(P)H:menadione reductase activities in periplasm and cytosol corresponded to the amplification of menadione-catalyzed LC, and outer and cytoplasmic membranes were only slightly involved in the LC. The total activity and Vmax of NAD(P)H:menadione reductase in the cytoplasm were greater than those in the periplasm. A transient increase in menadione-catalyzed LC was observed in the exponential phase and the LC decreased in the stationary phase during growth of E. coli. Menadione-catalyzed LC was sensitive to antibiotic action. A decrease in menadione-catalyzed LC by the impairment of membrane functions and by the inhibition of protein synthesis was observed at 5 min and 3 hr, respectively. These findings suggest the possibility that menadione-catalyzed luminol chemiluminescent assay is applicable to rapid antimicrobial assay because LC is sensitive to the change in growth and cytotoxic events caused by antimicrobial agents.
