Sensing corrosion within an artificial defect in organic coating using SECM

The electrochemical reactivity of a defect in organic coating was investigated by electrochemical noise (EN) and scanning electrochemical microscopy (SECM). Time dependent EN spectra and SECM image on a metal with defective organic coating was measured, and corresponding EN frequency domain spectra and probe approach curves (PACs) were used to obtain electrochemical reactivity information within the coating defects. All time domain and frequency domain analyses, and SECM measurements were successful indicators of corrosion intensity within the defect. The amplitude of electrochemical current noise (ECN) and the low-frequency plateau of the power spectral density (PSD) WL increased significantly with corrosion intensity.

An enzymatic calculation system based on electrochemiluminescence and fluorescence of luminol and cyclic voltammetry of ferrocene methanol

In this work, a biomolecular calculation system was developed based on electrochemiluminescence (ECL) and fluorescence emission (FL) of luminol and cyclic voltammetry (CV) of ferrocene methanol (FMA). When triethylamine (TEA) was added in luminol solution as a coreactant, a great ECL peak at 1.1 V was observed. While the further addition of enzymatic system, esterase/ethyl butyrate (EB), would significantly lower the ECL response. On the other hand, TEA could quench the FL signal of luminol at 430 nm, while the injection of esterase/EB in the luminol solution could enhance the FL signal. Furthermore, FMA exhibited a CV peak pair at 0.2 V and could decrease the ECL signal greatly in the luminol/TEA solution. Based on these interesting results, a 3-input and 5-output biomolecular logic gate was established with TEA, FMA and esterase/EB as inputs and the ECL, CV and FL signals as outputs. Moreover, some nonarithmetic logic devices, such as an encoder, a decoder, a 3-input keypad lock and two dual transfer gates were elaborately designed on the same platform. This work presented a new example of how the complexity of biocomputing system could be enhanced either by increasing the number of outputs of traditional logic gates or by fabricating some nonarithmetic logic devices based on the same simple electrochemical system.

Impact of Plasmonic Photothermal Effects on the Reactivity of Au Nanoparticle Modified Graphene Electrodes Visualized Using Scanning Electrochemical Microscopy

Atomically thin graphene electrodes enable the modulation of interfacial reactivity by means of underlying substrate effects. Here we show that plasmonic excitation of microscopic arrays composed of 50 nm Au nanoparticles situated underneath a graphene interface results in localized enhancements on the electrochemical readout. We used scanning electrochemical microscopy (SECM) in the feedback and H2O2 collection modes to identify the role of the generated plasmons on the electrochemical response. Using electrochemical imaging, supported by finite-element method simulations, we confirmed that a temperature rise of up to ?30 K was responsible for current enhancements observed for mass transfer- limited reactions. On single-layer graphene (SLG) we observed a shift in the onset of H2O2 generation which we traced back to photothermal induced kinetic changes, raising ko? from 1.1 ¡Á 10-8 m/s to 2.2 ¡Á 10-7 m/s. Thicker 10-layer graphene electrodes displayed only a small kinetic difference with respect to SLG, suggesting that photothermal processes, in contrast to hot carriers, are the main contributor to the observed changes in interfacial reactivity upon illumination. SECM is demonstrated to be a powerful technique for elucidating thermal contributions to reactive enhancements, and presents a convenient platform for studying sublayer and temperature-dependent phenomena over individual sites on electrodes.

Disposable biosensors for determination of biogenic amines

This work reports monoamine oxidase (MAO)/horseradish peroxidase (HRP) and diamine oxidase (DAO)/horseradish peroxidase (HRP) based biosensors using screen-printed carbon electrodes for the determination of biogenic amines (BA). The enzymes have been covalently immobilized onto the carbon working electrode, previously modified by an aryl diazonium salt, using hydroxysuccinimide and carbodiimide. The detection has been performed by measuring the cathodic current due to the reduction of the mediator hydroxymethylferrocene at a low potential, 250. mV vs screen-printed Ag/AgCl reference electrode. The experimental conditions for the enzymes immobilization, as well as for the main variables that can influence the chronoamperometric current have been optimized by the experimental design methodology. Under these optimum conditions, the disposable biosensors have been characterized. A linear response range from 0.2 up to 1.6 muM and from 0.4 to 2.4 muM of histamine was obtained for DAO/HRP and MAO/HRP based biosensors, respectively. The biosensor construction was highly reproducible, yielding relative standard deviations of 10% and 11% in terms of sensitivity for DAO/HRP and MAO/HRP based biosensors, respectively. The capability of detection, 0.18 ¡À 0.01 muM in the case of DAO/HRP and 0.40 ¡À 0.04 muM (alpha=0.05 and beta=0.005) for MAO/HRP based biosensors, and the biosensor sensitivity towards different BA has also been analyzed. Finally, the developed biosensors have been applied to the determination of the total amine content in fish samples.

Mechanoelectrochemistry of soft electroactive materials via surface-tracked scanning electrochemical microscopy

Real time measurement of time-correlated ion transport and volumetric changes in electroactive materials is necessary to understand and model mechanoelectrochemistry. Reversible reduction and oxidation of soft electroactive materials such as conducting polymers result in the deformation of the material due to ion transport into and out of the polymer backbone. In cells, ion transport and volumetric expansion are collectively responsible for homeostasis that is essential for life functions and hence, mechanoelectrochemistry of cells is essential to understand cell and developmental biology. The characterization methods required to investigate mechanoelectrochemistry require nanoscale spatial resolution for the imaging of a redox active site in a polymer or a small group of transmembrane proteins in a single cell. Towards this goal, we present an imaging technique using scanning electrochemical microscopy (SECM) hardware with shear-force (SF) feedback for high bandwidth mechanoelectrochemistry characterization. In this proceedings article, we demonstrate this technique referred to as surface-tracked scanning electrochemical microscopy technique (ST-SECM) that is realized by measuring the structural feedback of the glass electrode to position the electrode in 10s of nanometers above the surface of a polypyrrole membrane doped with dodecylbenzenesulfonate (PPy(DBS)). Two ultra-microelectrodes of controlled dimensions (of 20 mum and 30 mum glass diameter) were fabricated using a hydrofluoric acid etching technique and were used to generate a spatially correlated ion storage map of PPy(DBS). We compare the developed technique to a three-dimensional discrete scan over the surface and show that a ST-SECM technique produces a higher resolution and takes approximately 200 fewer minutes as compared to the conventional technique.

Scanning electrochemical microscope studies of dye regeneration in indoline (D149)-sensitized ZnO photoelectrochemical cells

A scanning electrochemical microscope (SECM) in the feedback and generation-collection modes was used to investigate the regeneration of photoexcited dye cations at the semiconductor/electrolyte interface in a dye-sensitized solar cell (DSSC) based on ZnO/D149. An effective dye regeneration rate constant kox of 9.55 ¡Á 107 cm 9/2 mol-3/2 s-1 was obtained from feedback mode experiments at different wavelengths and light intensities on ZnO/D149 electrodes. Illuminated regions of the dye-sensitized electrodes could be differentiated from non-illuminated regions by local imaging in SECM generation-collection experiments with I- as redox mediator. We also report SECM feedback measurements on non-illuminated dye-sensitized electrodes to investigate the electron transfer kinetics of dissolved redox couples at the underlying FTO substrate.

The reactions of acylferrocenes with samarium diiodide: Reduction, deoxygenation, reductive coupling and rearrangement

Acylferrocenes reacted with samarium diiodide in the presence of water to give the corresponding (alpha-hydroxyalkyl)ferrocenes or alkylferrocenes depending on the reaction time and temperature. On treatment with samarium diiodide in the absence of water, ferrocenecarbaldehyde underwent a reductive coupling to give pinacols, whereas acetylferrocene yielded 3,3-diferrocenyl-2-butanone and 2,3-diferrocenyl-2-butene via the subsequent rearrangement and deoxygenation.

Size-dependent efficiency of electron transfer at suspended ferrocenyl jumbo particles

Ferrocenylmethanol acrylate (FcMA)-immobilized polystyrene latex particles were synthesized by copolymerizing FcMA and styrene in the presence of polystyrene latex suspensions with eight different diameters ranging from 0.084 to 1.7 mum. The amounts of the ferrocenyl moiety loaded on one particle were proportional to the radii, a. The proportionality suggests the uniform distribution of the ferrocenyl moiety over the particle, of which concentration was 0.18 M. The aqueous suspensions, which were stable in the presence of a surfactant, exhibited reversible voltammetric waves for the ferrocenyl moiety. The peak current was controlled by diffusion of the latex particles. The efficiency of the reaction was obtained from the ratio of the observed current to the theoretical one which was estimated from the number of the ferrocenyl moieties and the diffusion coefficient of the particle by the Stokes-Einstein relation. The ratio was proportional to a-0.47, whereas it might be a0 for an ideal particle without any size effect. This relation was explained in terms of the contribution of rotational diffusion of redox particles.

Electrocatalytic processes promoted by diamond nanoparticles in enzymatic biosensing devices

We have developed a biosensing platform for lactate determination based on gold electrodes modified with diamond nanoparticles of 4 nm of nominal diameter, employing the enzyme lactate oxidase and (hydroxymethyl)ferrocene (HMF) as redox mediator in solution. This system displays a response towards lactate that is completely different to those typically observed for lactate biosensors based on other nanomaterials, such as graphene, carbon nanotubes, gold nanoparticles or even diamond nanoparticles of greater size. We have observed by cyclic voltammetry that, under certain experimental conditions, an irreversible wave (E0 = +0.15 V) appears concomitantly with the typical FeII/FeIII peaks (E0 = +0.30 V) of HMF. In this case, the biosensor response to lactate shows simultaneous electrocatalytic peaks at +0.15 V and +0.30 V, indicating the concurrence of different feedback mechanisms. The achievement of a biosensor response to lactate at +0.15 V is very convenient in order to avoid potential interferences. The developed biosensor presents a linear concentration range from 0.02 mM to 1.2 mM, a sensitivity of 6.1 muA mM-1, a detection limit of 5.3 muM and excellent stability. These analytical properties compare well with those obtained for other lactate-based biosensors that also include nanomaterials and employ HMF as redox mediator.

A Feedback Control Approach to Organic Drug Infusions Using Electrochemical Measurement

Goal: Target-controlled infusion of anesthesia is a closed-loop automated drug delivery method with a computer-aided control. Our goal is to design and test an automated drug infusion platform for propofol delivery in total intravenous anesthesia (TIVA) administration. Methods: In the proposed method, a dilution chamber with first-order exponential decay characteristics was used to model the pharmacodynamics decay of a drug. The dilution chamber was connected to a flow system through an electrochemical cell containing an organic film-coated glassy carbon electrode as working electrode. To set up the feedback-controlled delivery platform and optimize its parameters, ferrocene methanol was used as a proxy of the propofol. The output signal of the sensor was connected to a PI controller, which prompted a syringe pump for feedback-controlled drug infusion. Results: The result is a bench-top drug infusion platform to automate the delivery of a propofol based on the measurement of concentration with an organic film-coated voltammetric sensor. Conclusion: To evaluate the performance characteristics of the infusion platform, the propofol concentration in the dilution chamber was monitored with the organic film-coated glassy carbon electrode and the difference between the set and measured concentrations was assessed. The feasibility of measurement-based feedback-controlled propofol delivery is demonstrated and confirmed. Significance: This platform will contribute to high-performance TIVA application of intravenous propofol anesthesia.
