Electrochemically driven catalysis of Rhizobium sp. NT-26 arsenite oxidase with its native electron acceptor cytochrome c552

We describe the catalytic voltammograms of the periplasmic arsenite oxidase (Aio) from the chemolithoautotrophic bacterium Rhizobium sp. str. NT-26 that oxidizes arsenite to arsenate. Electrochemistry of the enzyme was accomplished using its native electron transfer partner, cytochrome c552 (cyt c552), as a mediator. The protein cyt c552 adsorbed on a mercaptoundecanoic acid (MUA) modified Au electrode exhibited a stable, reversible one-electron voltammetric response at + 275 mV vs NHE (pH 6). In the presence of arsenite and Aio the voltammetry of cyt c552 is transformed from a transient response to an amplified sigmoidal (steady state) wave consistent with an electro-catalytic system. Digital simulation was performed using a single set of parameters for all catalytic voltammetries obtained at different sweep rates and various substrate concentrations. The obtained kinetic constants from digital simulation provide new insight into the kinetics of the NT-26 Aio catalytic mechanism.

Microfabrication and Characterization of Solid Surfaces Patterned with Enzymes or Antigen-Antibodies by Scanning Electrochemical Microscopy

The microfabrication and characterization of glass surfaces patterned with enzymes (diaphorase, horseradish peroxidase(HRP)) or antigen-antibodies (carcinoembryonic antigen (CEA), human chorionic gonadotropin (HCG) and human placental lactogen (HPL)) were studied using scanning electrochemical microscopy (SECM). Localized enzymes and antigen-antibody complexes with labeled enzymes were characterized on the basis of detection of catalytic current for ferrocenylmethanol by SECM. The SECM technique was extended to the enzyme-linked immunosorbent assay (ELISA). This method detects as low as ? 104 CEA molecules in a single microspot. We also demonstrated a novel dual assay using microfabricated glass substrates with anti-HCG and anti-HPL microspots.

?Development and application of analytical detection techniques for droplet-based microfluidics?-A review

Droplet-based microfluidics has emerged as a powerful platform for high-throughput and low-volume analysis and screening. At present, droplet-based microfluidics is transitioning from the proof-of-concept stage to real-world applications. During this process, analytical detection techniques play indispensable roles for successfully implementing droplet-based chemical or biological assays. In this review, we provide an overview of recent developments in analytical techniques for droplet analysis and elucidate the advantages and limitations of each technique. We cover the majority of technology categories, including optical detection, electrical detection, mass spectrometry, and nuclear magnetic resonance spectroscopy. Additionally, we highlight new research areas that have been enabled by these technical advances. Finally, we provide perspectives on both future technological directions and potential enabling applications.

Electrochemical quantification of extracellular local H2O2 kinetics originating from single cells

Aims: H2O2 is produced by all eukaryotic cells under physiological and pathological conditions. Due to its enormous relevance for cell signaling at low concentrations and antipathogenic function at high concentrations, precise quantification of extracellular local hydrogen peroxide concentrations ([H2O2]) originating from single cells is required. Results: Using a scanning electrochemical microscope and bare platinum disk ultramicroelectrodes, we established sensitive long-term measurements of extracellular [H2O2] kinetics originating from single primary human monocytes (MCs) ex vivo. For the electrochemical techniques square wave voltammetry, cyclic and linear scan voltammetry, and chronoamperometry, detection limits for [H2O2] were determined to be 5, 50, and 500 nM, respectively. Following phorbol ester stimulation, local [H2O2] 5-8 mum above a single MC increased by 3.4 nM/s within the first 10 min before reaching a plateau. After extracellular addition of H2O2 to an unstimulated MC, the local [H2O2] decreased on average by 4.2 nM/s due to degradation processes of the cell. Using the scanning mode of the setup, we found that H2O2 is evenly distributed around the producing cell and can still be detected up to 30 mum away from the cell. The electrochemical single-cell measurements were validated in MC populations using electron spin resonance spectroscopy and the Amplex UltraRed assay. Innovation and Conclusion: We demonstrate a highly sensitive, spatially, and temporally resolved electrochemical approach to monitor dynamics of production and degradation processes for H2O2 separately. Local extracellular [H2O2] kinetics originating from single cells is quantified in real time.

Mechanism of initiation of the radical chain oxidation by molecular oxygen of hydroxymethylferrocene and its ethyl ether in organic solvents

Autooxidation of ethoxymethylferrocene at 30-50C promoted by the participation of strong and weak carboxylic acids HX is studied. The radical chain mechanism of the process is established, its kinetics characteristics are determined as well as the composition of the products among which other derivatives of ferrocene have been found. Based on the results of the present study and the earlier obtained data on oxidation of hydroxymethylferrocene a mechanism of initiation of the chains general for both metallocomplexes is suggested. It includes the formation of the intermediate CH2OR (R = H, C2H5) and its subsequent oxidative transformations leading to the formation of the peroxide radical C5H 4Fe+?C5H4-CH2O 2 ? and ROH. The role of the approaching and orientation effect in transformations of this intermediate is discussed as well as the mechanism of the investigated reaction in general.

Ordered Array Electrodes Fabricated by a Mask-Assisted Electron-Beam Method as Platforms for Studying Kinetic and Mass-Transport Phenomena on Electrocatalysts

This work describes a method for fabrication of extensive ordered arrays of microelectrodes with varied geometries, surrounded either by an insulating surface of poly(methyl methacrylate) (PMMA) or by a conductive material such as gold or glassy carbon (GC). The method is based on procedures from electron beam lithography (EBL) but, in contrast to classic EBL, it can be applied by using widely available conventional SEM instruments that are not specifically tailored for EBL operation. The electron gun of the SEM is used to irradiate and modify a PMMA film that is covered by a micro- or nano-structured mask (i.e., a TEM grid), which is further selectively revealed. Each array can be evaluated in two configurations, when it is surrounded by the PMMA film, and when it is in contact with the exposed support after PMMA removal. The first configuration is useful to evaluate the electrochemical behavior of pure microelectrode arrays for correlating it with model equations. The second configuration is particularly useful when the substrate material by itself is inactive for the studied reaction. In the latter case, any detected differences between the electrochemical behavior of the PMMA-coated array and that of the bi-component array should come from the contributions of the microelectrode boundaries. These arrays were employed for studying the hydrogen oxidation reaction in alkaline medium on Au/Rh and on GC/Rh in order to detect possible kinetic interactions of both components at the heterojunctions.

Carbon paste-based ion-selective dual function microelectrodes for SECM measurements

A description of the preparation and characterization of 25 mum diameter modified carbon paste-based Cu2+ ion-selective electrodes are reported. The electrodes have a linear potential response within the 10-3 to 10-6 M range and a 16 s response time. A substantial benefit of this new type of ion-selective microelectrode (ISME) is the capability to use them as a dual function tip, in either the amperometric or the potentiometric mode of scanning electrochemical microscopy (SECM). The applications reported also support the usefulness of copper ion-selective carbon paste microelectrodes in SECM potentiometric imaging.

Direct growth of vertically aligned carbon nanotubes on a planar carbon substrate by thermal chemical vapour deposition

Uniform, vertically aligned multiwalled carbon nanotube arrays (VACNTs) were grown on glassy carbon-like thin films by thermal chemical vapour deposition (CVD). Thin (5 nm) aluminum and iron catalyst layers were pre-deposited by evaporation on the carbon substrates and VACNTs were grown at 750 C by water-assisted CVD using ethylene as the carbon source. The aluminum layer was shown to be essential for aligned nanotube growth. VACNT arrays adhered strongly to the carbon film with low contact resistance between the VACNTs and the substrate. The VACNT arrays grown directly on the planar conducting carbon substrate have attractive properties for use as electrodes. Excellent voltammetric characteristics are demonstrated after insulating the arrays with a dielectric material.
