Electron-Transfer Studies of Model Redox-Active Species (Cationic, Anionic, and Neutral) in Deep Eutectic Solvents

The redox potentials of electroactive species are significantly influenced by the solvation characteristics of the medium. This is manifested in the shift of half-peak potentials with the change in the solvent medium. There have been many approaches till date, both experimental and theoretical to understand the role of molecular solvents in the peak potentials of redox species. The electrochemical studies reported here are aimed at understanding the effect of deep eutectic solvents (DESs) which is distinct from conventional solvents in terms of highly concentrated ionic composition, on the half-peak potentials of some standard redox reactions. The redox species selected for this study are distinct either in terms of their charge [Fe(CN)64-/3-, Ru(NH3)62+/3+, and ferrocene methanol, FcMeOH0/+] or their hydrophilic/hydrophobic properties [methyl viologen and ferrocene]. The redox potentials are compared with the values obtained in the aqueous medium which is very well characterized in terms of solvent reorganization energy and free-energy changes. The cyclic voltammetric behavior of the redox species in DES is significantly different from that of aqueous medium. The diffusion coefficients of the redox species in DES measured by EIS and cyclic voltammetry showed significant deviations from that predicted by Stokes-Einstein equation, indicating the dominant effect of Coulombic interactions within the components of DES.

Synthesis of citric-acid-based dendrimers decorated with ferrocenyl groups and investigation of their electroactivity

Fc (ferrocene)-functionalized citric acid dendrimers were successfully synthesized via the reaction of citric acid dendrimers with ferrocene methanol using dicyclohexylcarbodiimide. ClOC?PEG?COCl was used as the core, and the related dendrimers were synthesized divergently. Subsequently, each generation was functionalized with ferrocene methanol. The obtained Fc-dendrimers were characterized by 1H NMR and FTIR spectroscopy. We have studied the relocation of electrons around the peripheries of dendrimers and between their redox terminals and electrodes by studies of the electrochemistry of dendrimers awarding metallocenes as functional?s groups, because these compounds can be stabilized together their oxidized and their reduced states. In addition, the voltammograms of each Fc-functionalized generation were studied and the influence of scan rate, solvent, and [Fe] unit and the concentration of the Fc-dendrimers were investigated.

Dehydrogenative coupling as an efficient route to ferrocene functionalized siloxanes

Ferrocene grafted siloxanes were prepared in high yields (?79-97%) via Rh-catalyzed dehydrogenative coupling of a series of monomeric, polymeric, and cyclic hydrosiloxanes with ferrocenemethanol. Wilkinson’s catalyst was the most efficient of those surveyed (Karstedt’s catalyst, H2PtCl6, Co2 (CO)8, 10% Pd/C, 10% Pt/C, 5% Rh/C) with respect to yield and selectivity. Benzene and toluene were better solvents than tetrahydrofuran and methylene chloride.

Real-time monitoring of extracellular pH using a pH-potentiometric sensing SECM dual-microelectrode

Extracellular pH can indicate the variation in organelle function and cell state. It is important to measure extracellular pH (pHe) with a controllable distance. In this work, a potentiometric SECM dual-microelectrode was developed to monitor the pHe of MCF-7 cells under electrical stimulation. The distance between the dual-microelectrode and the cells was determined first with a gold microelectrode by recording the approaching curve, and the pH was determined using an open-circuit potential (OCP) technique with a polyaniline-modified Pt microelectrode. The pH microelectrode showed a response slope of 53.0 ¡À 0.4 mV/pH and good reversibility from pH 4 to pH 8, fast response within 10 s, and a potential drift of 1.13% for 3 h, and thus was employed to monitor the pHe of stimulated cells. The value of pHe decreased with the decrease in the distance to cells, likely due to the release of H+. With an increase in the stimulation potential or time, the pHe value decreased, as the cell membrane became more permeable, which was verified by fluorescence staining of calcein-AM/PI (propidium iodide). Based on these results, this method can be widely applied for determining the species released by biosystems at a controllable position.

Gold Fibers as a platform for biosensing

A new form of high surface bioelectrode based on electrospun gold microfiber with-immobilized glucose oxidase was developed. The gold fibers were prepared by electroless deposition of gold nanoparticles on a poly(acrylonitrile)-HAuCl4 electrospun fiber. The material was characterized using electron microscopy, XRD and BET, as well as cyclic voltammetry and biochemical assay of the immobilized enzyme. The surface area of the gold microfibers was 2.5 m2/g. Glucose oxidase was covalently crosslinked to the gold surface using cystamine monolayer and glutardialdehyde, and portrayed characteristic catalytic currents for oxidizing glucose using a ferrocene methanol mediator. Limit of detection of glucose is 0.1 mM. The K m of the immobilized enzyme is 10 mM, in accordance with other reports of immobilized glucose oxidase. The microfiber electrode was reproducible and showed correlation between fiber weight, cathodic current and enzymatic loading.

Fructose biosensor based on D-fructose dehydrogenase immobilised on a ferrocene-embedded cellulose acetate membrane

The prevention of ferrocene leakage from an electrode by physical retention of mediator in a cellulose acetate membrane matrix is reported here for the first time. Five types of cellulose acetate membranes were prepared, containing 1.8, 5.3, 8.5, and 20.0% of ferrocene and a membrane containing 1.8% of ferrocene and 0.05% of Nafion in the matrix. All the membranes tested, including a cellulose acetate membrane without ferrocene, were much more resistant to ascorbate interference (12-69 nA mM-1) in comparison to an uncovered glassy carbon electrode (1152 nA mM-1). With increasing amount of ferrocene in the membrane, a decreasing ability of the membrane to retain mediator was observed. Ferrocene-embedded membranes were successfully applied in the construction of a fructose biosensor by immobilisation of PQQ-dependent fructose dehydrogenase. A biosensor with a membrane containing 20.0% of ferrocene in the matrix exhibited the lowest detection limit (3 muM), the shortest response time (45 s) and the highest sensitivity (232 nA mM-1). However, this biosensor was unstable because of ferrocene leaching and after 9 h of continuous use only 15% of the initial activity was observed. The biosensor with a cellulose acetate membrane containing 1.8% of ferrocene and 0.05% of Nafion had better stability characteristics, and retained almost 40% of the initial response after 8 h of continuous use, with similar sensitivity (226 nA mM-1) and response time (75 s).

Sensing polymer inhomogeneity in coated metals during the early stages of coating degradation

Negative-feedback scanning electrochemical microscopy (SECM) is successfully applied to visualize spatially resolved differences in the topography of coated metal samples upon exposure to aqueous electrolyte solutions of different composition. This method allows the investigation of the uptake of reactants from the electrolyte phase through the polymeric matrix to the metal/polymer interface to be performed even at early exposures. Yet, the method must be carefully checked to discard transport processes from the organic matrix into the solution phase, such as those related to lixiviation. In this later case, the topography of the polymer layer may evolve with time accordingly, not longer exclusively responding to the uptake by the polymer matrix of components from the electrolyte phase. Furthermore, lixiviated species may also react with the SECM tip, eventually leading to the continuous modification of the active surface area of the electrode during the measurements. In this work, the effect of lixiviation from a nickel foil coated with plasticized PVC (PVC Plastisol) on its topographic characterization by SECM was investigated.

Hybrid carbon based nanomaterials for electrochemical detection of biomolecules

By combining different allotropic forms of carbon at the nanoscale it is possible to fabricate tailor made surfaces with unique properties. These novel materials have shown high potential especially in the electrochemical detection of different biomolecules, such as dopamine, glutamate and ascorbic acid, which are important neurotransmitters in the mammalian central nervous system. Thus, more information about their material properties must be obtained in order to realize their high potential to the maximum. The results presented in this review clearly point out that although there is an extensive amount of data available on the structural, chemical and electrochemical properties on different carbon nanoforms, the data are scattered, often inconsistent and even contradictory. Hybrid carbon nanomaterials are much less investigated than the individual allotropes, but based on the existing data they possess extremely interesting electrochemical properties. Thus, it is of utmost importance to carry out extensive step-by-step characterization of these materials by utilizing combination of detailed computational and experimental work. In this way it will become possible to avoid approaches to material design that are based solely on trial-and-error approach, which has, unfortunately, been more a rule than an exception.

Formation of mixed organic layers by stepwise electrochemical reduction of diazonium compounds

This work describes the formation of a mixed organic layer covalently attached to a carbon electrode. The strategy adopted is based on two successive electrochemical reductions of diazonium salts. First, bithiophene phenyl (BTB) diazonium salt is reduced using host/guest complexation in a water/cyclodextrin (beta-CD) solution. The resulting layer consists of grafted BTB oligomers and cyclodextrin that can be removed from the surface. The electrochemical response of several outer-sphere redox probes on such BTB/CD electrodes is close to that of a diode, thanks to the easily p-dopable oligo(BTB) moieties. When CD is removed from the surface, pinholes are created and this diode like behavior is lost. Following this, nitrophenyl (NP) diazonium is reduced to graft a second component. Electrochemical study shows that upon grafting NP insulating moieties, the diode-like behavior of the layer is restored which demonstrates that NP is grafted predominately in the empty spaces generated by beta-CD desorption. As a result, a mixed BTB/NP organic layer covalently attached to a carbon electrode is obtained using a stepwise electrochemical reduction of two diazonium compounds.

Co-detection of dopamine and glucose with high temporal resolution

Neuronal activity and brain glucose metabolism are tightly coupled, where triggered neurotransmission leads to a higher demand for glucose. To better understand the regulation of neuronal activity and its relation to high-speed metabolism, development of analytical tools that can temporally resolve the transients of vesicular neurotransmitter release and fluctuations of metabolites such as glucose in the local vicinity of the activated neurons is needed. Here we present an amperometric biosensor design for rapid co-detection of glucose and the neurotransmitter dopamine. The sensor is based on the immobilization of an ultra-thin layer of glucose oxidase on to a gold-nanoparticle-covered carbon fiber microelectrode. Our electrode, by altering the potential applied at the sensor surface, allows for the high-speed recording of both glucose and dopamine. We demonstrate that, even though glucose is electrochemically detected indirectly through the enzymatic product and the electroactive dopamine is sensed directly, when exposing the sensor surface to a mixture of the two analytes, fluctuations in glucose and dopamine concentrations can be visualized with similar speed and at a millisecond time scale. Hence, by minimizing the enzyme coating thickness at the sensor surface, dual detection of glucose and dopamine can be realized at the same sensor surface and at time scales necessary for monitoring fast metabolic alterations during neurotransmission.
