Abstract
Peroxidase enzymes enable the construction of electrochemical sensors for highly sensitive and selective quantitative detection of various molecules, pathogens and diseases. Herein, we describe the immobilization of a peroxidase from Bacillus s. (BsDyP) on electrochemically reduced graphene oxide (ERGO) deposited on indium tin oxide (ITO) and polyethylene terephthalate (PET) layers. XRD, SEM, AFM, FT‐IR and Raman characterization of the sensor confirmed its structural integrity and a higher enzyme surface occupancy. The BsDyP‐ERGO/ITO/PET electrode performed better than other horseradish peroxidase‐based electrodes, as evinced by an improved electrochemical response in the nanomolar range (linearity 0.05–280 μM of H2O2, LOD 32 nM). The bioelectrode was mechanically robust, active in the 3.5–6 pH range and exhibited no loss of activity upon storage for 8 weeks at 4 °C.

Abstract
Challenges facing enzyme-based electrochemical sensors include substrate specificity, batch to batch reproducibility, and lack of quantitative metrics related to the effect of enzyme immobilization. We present a quick, simple, and general approach for measuring the effect of immobilization and cross-linking on enzyme activity and substrate specificity. The method can be generalized for electrochemical biosensors using an enzyme that releases hydrogen peroxide during its catalytic cycle. Using as proof of concept RgDAAO-based electrochemical biosensors, we found that the Michaelis-Menten constant (Km) decreases post immobilization, hinting at alterations in the enzyme kinetic properties and thus substrate specificity. We confirm the decrease in Km electrochemically by characterizing the substrate specificity of the immobilized RgDAAO using chronoamperometry. Our results demonstrate that enzyme immobilization affects enzyme substrate specificity and this must be carefully evaluated during biosensor development.

Abstract
Oxidative stress plays an important role in the pathogenesis of many diseases, while the exact mechanism that hydrogen peroxide (H2O2) as one of the most abundant reactive oxygen species (ROS) exerts its influence on oxidative stress remains unclear. We developed a novel turn-on ratiometric electrochemical sensor for the detection of H2O2 in blood samples. The electrochemical probe 5-(1,2-dithiolan-3-yl)-N-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)pent-anamide (BA) was designed and synthesized for the selective detection of H2O2 via a one-step amide reaction. Meanwhile, Nile Blue A (NB) was optimized as an internal reference molecule, thus enabling accurate quantification of H2O2 in a complex environment. BA and NB were then co-assembled onto a carbon fiber microelectrode (CFME) coated with Au cones. The oxidation peak current ratio between BA and NB demonstrated good linearity with the logarithm of the H2O2 concentration values ranging from 0.5 μM to 400 μM with a low detection limit of 0.02 μM. The developed sensor showed remarkable selectivity against potential interferences in whole blood samples, especially for ascorbic acid, uric acid, and dopamine. In combination with the unique characteristics of CFME, such as a small size and good biocompatibility, the microsensor was used for rapid analysis of one drop of whole blood sample. This sensor not only creates a new platform for the detection of H2O2 in whole blood samples, but also provides a new design strategy of other ROS analysis for early diagnosis of ROS-related diseases, drug discovery processes, and pathological mechanisms.

Abstract
Enzyme-catalyzed reactions are complicated and their kinetics depend on various chemical and physical factors. In a simple enzyme-catalyzed reaction, the enzyme kinetics often involve two or more substrates. However, this complexity is often ignored when studying enzyme kinetics or determining enzyme activity. Such an example is horseradish peroxidase (HRP), whose activity and kinetics in the reduction of H2O2 are usually detected and studied using spectroanalysis, with guaiacol (GA) as the hydrogen donor. In this process, the concentrations of two substrates, GA and H2O2, both change, which makes the practical detection, based on determination of the GA oxydate, GA(O), totally wrong. In this study, we introduce a new electrochemical method for detecting the specific activity (SA) and studying the enzyme kinetics of HRP. This electrochemical method was used to directly detect one substrate (H2O2) while the concentration of the other substrate (GA) was kept constant by adding ascorbic acid to the system to reduce GA(O) and regenerate GA. For the first time, this HRP-catalyzed reaction, including the mechanism and kinetics, was investigated precisely using a simple electrochemical method. The maximum SA and reaction rate constant k1 were reliably detected and calculated. The proposed method indicated that the SA of commercially available HRP (300 U mg-1 detected by spectroanalysis) was 1228.8 U mg-1 at a GA concentration of 4.5 mM, and up to 2049.9 U mg-1 as the GA concentration tended toward infinity. Our results suggest that reported methods for detecting enzyme activity and/or kinetics should be re-examined according to the catalytic mechanism of the enzyme.

Abstract
The analysis of protein biomarkers is of great importance in the diagnosis of diseases. Although many convenient and low-cost electrochemical approaches have been extensively investigated, they are not sensitive enough in the detection of protein biomarkers with low concentrations in physiological environments. Here, this study reports a novel organic-electrochemical-transistor-based biosensor that can successfully detect cancer protein biomarkers with ultrahigh sensitivity. The devices are operated by detecting electrochemical activity on gate electrodes, which is dependent on the concentrations of proteins labeled with catalytic nanoprobes. The protein sensors can specifically detect a cancer biomarker, human epidermal growth factor receptor 2, down to the concentration of 10-14 g mL-1 , which is several orders of magnitude lower than the detection limits of previously reported electrochemical approaches. Moreover, the devices can successfully differentiate breast cancer cells from normal cells at various concentrations. The ultrahigh sensitivity of the protein sensors is attributed to the inherent amplification function of the organic electrochemical transistors. This work paves a way for developing highly sensitive and low-cost biosensors for the detection of various protein biomarkers in clinical analysis in the future.

Abstract
Covalent immobilization of enzymes at electrodes via amide bond formation is usually carried out by a two-step protocol, in which surface carboxylic groups are first activated with the corresponding cross-coupling reagents and then reacted with protein amine groups. Herein, it is shown that a modification of the above protocol, involving the simultaneous incubation of tobacco peroxidase and the pyrolytic graphite electrode with the cross-coupling reagents produces higher and more stable electrocatalytic currents than those obtained with either physically adsorbed enzymes or covalently immobilized enzymes according to the usual immobilization protocol. The remarkably improved electrocatalytic properties of the present peroxidase biosensor that operates in the 0.3 V ≤ E ≤ 0.8 V (vs SHE) potential range can be attributed to both an efficient electronic coupling between tobacco peroxidase and graphite and to the formation of intra- and intermolecular amide bonds that stabilize the protein structure and improve the percentage of anchoring groups that provide an adequate orientation for electron exchange with the electrode. The optimized tobacco peroxidase sensor exhibits a working concentration range of 10-900 μM, a sensitivity of 0.08 A M(-1) cm(-2) (RSD 0.05), a detection limit of 2 μM (RSD 0.09), and a good long-term stability, as long as it operates at low temperature. These parameter values are among the best reported so far for a peroxidase biosensor operating under simple direct electron transfer conditions.

Abstract
A highly sensitive electroanalytical method for determination of PQQ in solution down to subpicomolar concentrations is proposed. It is based on the heterogeneous reconstitution of the PQQ-dependent glucose dehydrogenase (PQQ-GDH) through the specific binding of its pyrroloquinoline quinone (PQQ) cofactor to the apoenzyme anchored on an electrode surface. It is shown from kinetics analysis of both the enzyme catalytic responses and enzyme surface-reconstitution process (achieved by cyclic voltammetry under redox-mediated catalysis) that the selected immobilization strategy (i.e., through an avidin/biotin linkage) is well-suited to immobilize a nearly saturated apoenzyme monolayer on the electrode surface with an almost fully preserved PQQ binding properties and catalytic activity. From measurement of the overall rate constants controlling the steady-state catalytic current responses of the surface-reconstituted PQQ-GDH and determination of the PQQ equilibrium binding (Kb = 2.4 × 10(10) M(-1)) and association rate (kon = 2 × 10(6) M(-1) s(-1)) constants with the immobilized apoenzyme, the analytical performances of the method could be rationally evaluated, and the signal amplification for PQQ detection down to the picomolar levels is well-predicted. These performances outperform by several orders of magnitude the direct electrochemical detection of PQQ in solution and by 1 to 2 orders the detection limits previously achieved by UV-vis spectroscopic detection of the homogeneous PQQ-GDH reconstitution.

Abstract
Thanks to its insensitivity to dioxygen and to its good catalytic reactivity, and in spite of its poor substrate selectivity, quinoprotein glucose dehydrogenase (PQQ-GDH) plays a prominent role among the redox enzymes that can be used for analytical purposes, such as glucose detection, enzyme-based bioaffinity assays, and the design of biofuel cells. A detailed kinetic analysis of the electrochemical catalytic responses, leading to an unambiguous characterization of each individual steps, seems a priori intractable in view of the interference, on top of the usual ping-pong mechanism, of substrate inhibition and of cooperativity effects between the two identical subunits of the enzyme. Based on simplifications suggested by extended knowledge previously acquired by standard homogeneous kinetics, it is shown that analysis of the catalytic responses obtained by means of electrochemical nondestructive techniques, such as cyclic voltammetry, with ferrocene methanol as a mediator, does allow a full characterization of all individual steps of the catalytic reaction, including substrate inhibition and cooperativity and, thus, allows to decipher the reason that makes the enzyme more efficient when the neighboring subunit is filled with a glucose molecule. As a first practical illustration of this electrochemical approach, comparison of the native enzyme responses with those of a mutant (in which the asparagine amino acid in position 428 has been replaced by a cysteine residue) allowed identification of the elementary steps that makes the mutant type more efficient than the wild type when cooperativity between the two subunits takes place, which is observed at large mediator and substrate concentrations. A route is thus opened to structure-reactivity relationships and therefore to mutagenesis strategies aiming at better performances in terms of catalytic responses and/or substrate selectivity.

Abstract
This paper reports that a bioarchitecture with two different active enzymes can be fabricated conveniently on a prepatterned surface by highly selective surface-templated layer-by-layer (LBL) assembly by coupling a bilayer of avidin/biotin-lactate oxidase (biotin-LOD) with a bilayer of avidin/biotin-horseradish peroxidase (biotin-HRP). The two different active enzymes can be utilized as excellent building blocks for the fabrication of well-defined 3D nanostructures with precise control of the position and height on the surface. In addition, the LBL assembled bienzyme structures are highly functional, and bioarchitectures based on LOD and HRP-mediated coupling reaction can be employed in a number of viable biosensing applications.

Abstract
We assembled multilayer films of glucose oxidase (GOx) and horseradish peroxidase (HRP) coimmobilized together with polyelectrolyte layers on the surface of silica microparticles. The influence of different polyelectrolyte combinations on the immobilization and functionality of the enzymes was examined for several multilayer configurations. Precomplexation of the enzymes with a polyvinylpyridine-based polyamine allowed the stable adsorption of enzyme layers without affecting their catalytic activity. The efficiency of the sequential reaction between GOx and HRP on the surface of the colloids was quantitatively analyzed and rationalized in terms of the kinetic parameters of both enzymes and the reaction-diffusion kinetics of the system. In the optimized configuration, with GOx and HRP coimmobilized in the same layer, the overall rate of hydrogen peroxide conversion was around 2.5 times higher than for GOx and HRP in separate layers or for equivalent amounts of both enzymes free in solution.

Abstract
A description of the implementation of the relaxation method with automatic mesh point allocation for immobilized enzyme electrodes is presented. The advantages of this method for the solution of coupled reaction-diffusion problems are discussed. The relaxation numerical simulation technique is combined with the Simplex fitting algorithm to extract kinetic parameters from experimental data. The results of the simulations are compared to experimental data from self-assembled multilayered electrodes comprised of glucose oxidase (GOx) and an Os modified redox mediator and found to be in excellent agreement.

Abstract
Films constructed layer-by-layer on electrodes with architecture {protein/hyaluronic acid (HA)}n containing myoglobin (Mb) or horseradish peroxidase (HRP) were protected against protein damage by H2O2 by using outer catalase layers. Peroxidase activity for substrate oxidation requires activation by H2O2, but {protein/HA}n films without outer catalase layers are damaged slowly and irreversibly by H2O2. The rate and extent of damage were decreased dramatically by adding outer catalase layers to decompose H2O2. Comparative studies suggest that protection results from catalase decomposing a fraction of the H2O2 as it enters the film, rather than by an in-film diffusion barrier. The outer catalase layers controlled the rate of H2O2 entry into inner regions of the film, and they biased the system to favor electrocatalytic peroxide reduction over enzyme damage. Catalase-protected {protein/HA}n films had an increased linear concentration range for H2O2 detection. This approach offers an effective way to protect biosensors from damage by H2O2.

Abstract
A sensitive and rapid electrochemical microchip fabricated by assembling a surface-functionalized poly(dimethylsiloxane) (PDMS) microchannel with an interdigitated array (IDA) gold electrode was developed for the detection of human cardiac troponin I (cTnI) in the early diagnosis of acute myocardial infarction. Anti-cTnI was immobilized onto the internal surface of the PDMS channel on which protein G layer had been generated by silanization. To reduce electrode fouling, a PDMS channel was assembled with an IDA chip after surface treatment. The detection experiments were performed with successive injection of cTnI, alkaline phosphatase (AP)-labeled anti-cTnI, and p-aminophenylphosphate. Then, cyclic voltammograms were obtained by the oxidation peak current proportionally to the concentration of enzymatic product, p-aminophenol. The optimal packing density of anti-cTnI on the surface of the PDMS channel was determined at the anti-cTnI concentration of 30 microg/ml for the highest electrochemical signal. These demonstrate that the proper orientation and best packing density of antibody as well as no electrode fouling contributed to the low detection limit (148 pg/ml) of cTnI within 8 min.

Abstract
De novo proteins from designed combinatorial libraries were bound to heme terminated gold electrodes. The novel heme proteins were shown to possess peroxidase activity, and this activity was compared to that of horseradish peroxidase and bovine serum albumin when immobilized in a similar fashion. The various designed proteins from the libraries displayed distinctly different levels of peroxidase activity, thereby demonstrating that the sequence and structure of a designed protein can exert a substantial effect on the peroxidase activity of immobilized heme.

Abstract
A biotin-lipopolysaccharide (biotin-LPS) conjugate was synthesized from LPS smooth from Salmonella minnesota, yielding a conjugate with a biotin/LPS ratio equal to 1:1 and endotoxic activity of 0.08 EU ng(-1). The conjugate was used in an amperometric competitive assay to determine endotoxins with endotoxin-neutralizing protein (ENP) as the recognition element. The assay is performed on a modified electrode, involving the covalent binding of carboxymethyl dextran (CMDex) to a cystamine-modified gold electrode and then the covalent binding of the recognition protein, ENP, to CMDex. The assay is carried out by incubating the modified electrode in an LPS sample to which biotin-LPS was added. Both species compete for the recognition sites on the modified surface. After the incubation stage and a careful rinsing, the electrode is immersed in a solution containing neutravidin-horseradish peroxidase conjugate (N-HRP), which binds to the sites containing biotin-LPS on the electrode. The system is rinsed and a current signal is generated by the addition of hydrogen peroxide and a redox mediator. The assay is able to detect LPS from Salmonella minnesota at concentrations as low as 0.1 ng ml(-1), equivalent to 0.07 EU ml(-1).

Abstract
In this study, neutravidin-coated screen-printed carbon sensors were fully characterized and further used for the amperometric detection of specific DNA sequences of human cytomegalovirus (HCMV DNA). For this purpose, we took advantage of an earlier established relationship between the amount of HRP affinity immobilized on the surface of the electrode and the steady-state current recorded in the presence of H(2)O(2) as substrate and the single electron donor [Os(III)(bpy)(2)pyCl](2+) as cosubstrate. After incubating a saturating concentration of biotinylated horseradish peroxidase (Bio-HRP) onto the neutravidin-modified sensors, a surface concentration of active HRP of 3.6 pmol cm(-2) was calculated from the measurement of the electrocatalytic plateau current value. This result indicates that monolayers of neutravidin were adsorbed on the screen-printed carbon sensors. These neutravidin-covered platforms were then used to immobilize biotinylated nucleic acid targets. After hybridization with a complementary digoxigenin-labeled detection probe, the extent of hybrids formed was determined with an anti-digoxigenin HRP conjugate. The biosensor assay was applied to the detection of a synthetic oligonucleotide target, and then to the determination of an amplified viral DNA sequence. Monolayers of HRP-labeled oligonucleotide hybrids were immobilized onto the sensing surface whereas one third of the surface was covered with HCMV DNA hybrids. On the other hand, detection limits of 200 pM and 1 nM were obtained for the short oligonucleotide and the longer DNA targets, respectively. Finally, we demonstrated that the sensitivity of the electrochemical assay could be significantly improved by using high concentrations of the reduced form of the mediator [Os(II)(bpy)(2)pyCl](+), thus allowing one to detect as low as 30 pM of amplified HCMV DNA fragment.

Abstract
The study of direct electron transfer between enzymes and electrodes is frequently hampered by the small fraction of adsorbed proteins that remains electrochemically active. Here, we outline a strategy to overcome this limitation, which is based on a hierarchical analysis of steady-state electrocatalytic currents and the adoption of the "binary activity" hypothesis. The procedure is illustrated by studying the electrocatalytic response of horseradish peroxidase (HRP) adsorbed on graphite electrodes as a function of substrate (hydrogen peroxide) concentration, electrode potential, and solution pH. Individual contributions of the rates of substrate/enzyme reaction and of the electrode/enzyme electron exchange to the observed catalytic currents were disentangled by taking advantage of their distinct dependence on substrate concentration and electrode potential. In the absence of nonturnover currents, adoption of the "binary activity" hypothesis provided values of the standard electron-transfer rate constant for reduction of HRP Compound II that are similar to those reported previously for reduction of cytochrome c peroxidase Compound II. The variation of the catalytic currents with applied potential was analyzed in terms of the non-adiabatic Marcus-DOS electron transfer theory. The availability of a broad potential window, where catalytic currents could be recorded, facilitates an accurate determination of both the reorganization energy and the maximum electron-transfer rate for HRP Compound II reduction. The variation of these two kinetic parameters with solution pH provides some indication of the nature and location of the acid/base groups that control the electronic exchange between enzyme and electrode.

Abstract
We developed a high-resolution scanning electrochemical microscope (SECM) for the characterization of various biological materials. Electrode probes were fabricated by Ti/Pt sputtering followed by parylene C-vapor deposition polymerization on the pulled optical fiber or glass capillary. The effective electrode radius estimated from the cyclic voltammogram of ferrocyanide was found to be 35 nm. The optical aperture size was less than 170 nm, which was confirmed from the cross section of the near-field scanning optical microscope (NSOM) image of the quantum dot (QD) particles with diameters in the range of 10-15 nm. The feedback mechanism controlling the probe-sample distance was improved by vertically moving the probe by 0.1-3 microm to reduce the damage to the samples. This feedback mode, defined as "standing approach (STA) mode" (Yamada, H.; Fukumoto, H.; Yokoyama, T.; Koike, T. Anal. Chem. 2005, 77, 1785-1790), has allowed the simultaneous electrochemical and topographic imaging of the axons and cell body of a single PC12 cell under physiological conditions for the first time. STA-mode feedback imaging functions better than tip-sample regulation by the conventionally available AFM. For example, polystyrene beads (diameter approximately 6 microm) was imaged using the STA-mode SECM, whereas imaging was not possible using a conventional AFM instrument.

Abstract
The catalytic responses obtained with step-by-step neutravidin-biotin deposition of successive monolayers of HRP are analyzed by means of cyclic voltammetry. The theoretical tools that have been developed allowed full characterization of the multilayered HRP coatings by means of a combination between closed-form analysis of limiting behaviors and finite difference numerical computations. An analysis of the experiments in which the number of monolayers was extended to 16 allowed an approximate determination of the average thickness of each monolayer, pointing to a compact arrangement of neutravidin and biotinylated HRP. The piling up of so many monolayers on the electrode allowed an improvement of the catalytic current by a factor of ca. 10, leading to very good sensitivities in term of cosubstrate detection.

Abstract
A novel flow-through immunosensing system for performing a multianalyte chemiluminescent determination in a single run was designed. A new analytical strategy of substrate zone-resolved technique was proposed. Using carcinoma antigen 125 (CA 125) and carcinoembryonic antigen (CEA) as model analytes, the capture antibodies for CA 125 and CEA were immobilized on an UltraBind aldehyde-activated membrane to act as an immunoreactor, to which the mixture of CA 125, CEA, and their corresponding tracers, horseradish peroxidase (HRP)-labeled anti-CA 125 and alkaline phosphatase (ALP)-labeled anti-CEA, was introduced for on-line incubation. The substrates for HRP and ALP were then delivered into the detection cell sequentially to perform substrate zone-resolved immunoassay by a sandwich format. Under optimal conditions, CA 125 and CEA could be assayed in the ranges of 5.0-100 units/mL and 1.0-120 ng/mL, respectively. The whole assay process including incubation, wash, detection, and regeneration could be completed in 35 min. The serum samples from the clinic were assayed with the proposed method, and the results were in acceptable agreement with the reference values. This method and the strategy of substrate zone-resolved technique could be further developed for high-throughput multianalyte immunoassay.

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.
