Thermal decomposition kinetics of ferrocene modified poly(epichlorohydrin- co-2-(methoxymethyl) oxirane) based polyurethane networks

We synthesized poly(epichlorohydrin-co-2-(methoxy)methyl oxirane) [poly(ECH-co-MOMO)] and ferrocene modified poly(epichlorohydrin-co-2-(methoxy) methyl oxirane) [poly(FECH-co-MOMO)] based polyurethane networks. The polyurethane networks were prepared from prepolymer diol, 1,6- hexamethylenediisocyanate (HDI), and HDI-trimer with an [NCO]/[OH] ratio of 1.05 and an [isocyanate trimer]/[total NCO] ratio of 0.3 followed by accelerated aging at 80 C for 72 h. Thermal decomposition kinetics of urethane networks were investigated by thermal gravimetric analysis (TGA). Both the iso-conversional and Vyazovkin methods were used to investigate the thermal decomposition behavior for evaluating kinetic parameter of poly(ECH-co-MOMO) and poly(FECH-co-MOMO) based polyurethane networks. The decomposition temperature of the poly(ECH-co-MOMO) based polyurethane network was lower than that of the poly(FECH-co-MOMO) based polyurethane network. From the Vyazovkin method, the maximum activation energies of poly(ECH-co-MOMO) and poly(FECH-co-MOMO) based polyurethane networks were 220 kJ/mol and 240 kJ/mol, respectively.

Enzymatic biosensors for the quantification of biogenic amines: a literature update

The present review emphasizes on the quantification of biogenic amines (BAs) which are regarded as a quality indicator of food freshness or spoilage and for evaluating microbial action while food processing. BAs have various potential adverse effects on human health and they are widely found in varying concentrations in different food stuffs. In the quest for a reliable method for their precise detection, BA biosensors have emerged as an efficient tool which enables rapid and accurate assessment in miniature form. Various combinations of amine oxidase enzymes have been used for the fabrication of biosensors in order to enhance specific biorecognition and signal transduction. This article also summarizes the widely employed components used in the construction of a pertinent biosensor and the research results conducted previously. The meticulous description regarding the choice of transducers and the significant role of mediators in a high response biosensor has been reviewed. Moreover, it also encompasses the utilization of highly attractive electrolytic characteristics of nanoparticles to enhance the specificity and accuracy of BA biosensors.

Acid-base and counter ion dependent solid-state assembly of a ferrocene beta-aminoalcohol and the corresponding ammonium salt

2-(Ferrocenylmethyl)amino-2-methylpropan-1-ol was synthesized and converted to the respective ammonium bromide ([1H]Br ? 2) and dihydrogenphosphate ([1H]H2PO4 ? 3). The solid-state structures of 1, 2 and the solvated salt 3 ¡¤ 1/6Et2O (3a) have been determined by X-ray diffraction. The solid-state assemblies of 1 and 2 are dominated by infinite ladder-like arrays interconnected by hydrogen bonds whereas the solid-state structure of 3a is built up from linear hydrogen-bonded dihydrogenphosphate chains, which are interlinked via hydrogen bonds to the cations [1H]+ into a complicated three-dimensional network. Compound 1 and its interactions with Bu4NBr and Bu4NH2PO4 in solution were further studied by electrochemical methods and NMR titrations.

An ultrasensitive and incubation-free electrochemical immunosensor using a gold-nanocatalyst label mediating outer-sphere-reaction-philic and inner-sphere-reaction-philic species

This communication reports a new nanocatalytic scheme based on the facts that the redox reaction between a highly outer-sphere-reaction-philic (OSR-philic) species and a highly inner-sphere-reaction-philic (ISR-philic) species is slow and that an OSR- and ISR-philic Au-nanocatalyst label can mediate the two different types of redox species. This scheme allows highly sensitive and incubation free detection of creatine kinase-MB.

Electrochemistry of redox mediators encapsulated within organically modified silicate matrix in the presence of TiO2 and palladium nanoparticles; Application on electroanalysis of ascorbic acid

The encapsulation of redox mediators (i.e. ferrocene methanol, potassium ferricyanide) within the nanostructured network of organically modified silicate (ormosil) on a electrode surface is studied. The redox electrochemistry of modified electrodes made by sol-gel processing of 3-aminopropyltrimethoxysialne (3-APTMS) and 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane containing aqueous solution of desired redox mediators (potassium ferricyanide or ferrocene methanol) on electrode surface is reported. The synthetic protocol of ormosil film preparation on electrode surface also enables the encapsulation of titania (TiO2) and palladium when suitable precursors of the same are incorporated during sol-gel processing. The ormosil films are characterized by Atomic force spectroscopy, EDX and cyclic voltammetry. The modified electrodes of three different types (Ormosil, Ormosil-TiO2, and Ormosil-TiO 2-Pd) together with either ferrocene methanol or potassium ferricyanide are made to understand the redox behaviour of these electron transfer mediators present within nanostructured domain useful in electrochemical sensing with following major findings: (1) the redox electrochemistry of ormosil-encapsulated ferrocene methanol/potassium ferricyanide show gradual improvement in reversible electrochemical behavior in the order of Ormosil-TiO2-Pd > Ormosil-TiO2 and Ormosil; (2) the presence of TiO2-Pd in ormosil shows better catalytic activity as compared to that of made with only TiO2 toward ascorbic acid (AA) oxidation; (3) ferrocene methanol encapsulated ormosil has been found relatively more efficient mediator as compared to that of potassium ferricyanide toward AA oxidation. The findings justify the novel approach on the fabrication of porous chemically modified electrode of suitable nanogeometry for electroanalytical applications.

A conductive hydrogel based on alginate and carbon nanotubes for probing microbial electroactivity

Some bacteria can act as catalysts to oxidize (or reduce) organic or inorganic matter with the potential of generating electrical current. Despite their high value for sustainable energy, organic compound production and bioremediation, a tool to probe the natural biodiversity and to select most efficient microbes is still lacking. Compartmentalized cell culture is an ideal strategy for achieving such a goal but the appropriate compartment allowing cell growth and electron exchange must be tailored. Here, we develop a conductive composite hydrogel made of a double network of alginate and carbon nanotubes. Homogeneous mixing of carbon nanotubes within the polyelectrolyte is obtained by a surfactant assisted dispersion followed by a desorption step for triggering electrical conductivity. Dripping the mixture in a gelling bath through simple extrusion or a double one allows the formation of either plain hydrogel beads or liquid core hydrogel capsules. The process is shown to be compatible with the bacterial culture (Geobacter sulfurreducens). Bacteria can indeed colonize the outer wall of plain beads or the inner wall of the conductive capsules’ shell that function as an anode from which electrons produced by the cells are collected.

Voltammetric study of inclusion of p-sulfonated thiacalix[n]arenes (n = 4, 6) toward ferrocenyl guests in aqueous solutions

Inclusion behavior of negatively charged host molecules, thiacalix[4]arene-p-tetrasulfonate (TC4AS) and [6]arene-p-hexasulfonate (TC6AS), toward (ferrocenylmethyl)trimethylammonium (FcCH2NMe3+), hydroxymethylferrocene (FcCH2OH), ferrocenecarboxylic acid (FcCOOH), and 1,1?-ferrocenedicarboxylic acid (Fc(COOH)2) was studied in aqueous solutions (pH 7.0) with cyclic voltammetry. Upon increasing the concentration of TC4AS to 4-fold of each guest, the anodic peak current density (jp,a) decreased, suggesting inclusion of the ferrocenyl guests in TC4AS. Also oxidation half-wave potential (E1/2) of FcCH2NMe3+, FcCH2OH, and FcCOOH was shifted to cathodic direction, showing preferential inclusion of the oxidative state. Inclusion of neutral guests such as FcCH2OH and Fc+COO- implies that hydrophobic interaction between TC4AS and the guests is the chief driving force for formation of host-guest assembly. The decrease of E1/2 for each guest was in the order: FcCH2NMe3+ > FcCH2OH > FcCOOH, suggesting that electrostatic interaction controls the preference toward oxidative form of the guest. Dicarboxylic Fc(COOH)2 showed decrease of jp,a but increase of E1/2 upon inclusion, suggesting TC4AS preferred reduced form Fc(COOH)2 to oxidized form Fc+(COO-)2. TC6AS behaved similarly to TC4AS but with larger decrease in of E1/2 and jp,a. The larger shift of E1/2 for inclusion of FcCOOH, the oxidative form of which is also neutral (Fc+COO-), than that attained with TC4AS endorses main role of hydrophobic interaction between TCnAS (n = 4, 6) and ferrocenyl guest molecules. Having the most preferential electrostatic interaction, kinetically stable complex was formed between TC6AS and FcCH2NMe3+.

Solution viscosity effects on the heterogeneous electron transfer kinetics of ferrocenemethanol in dimethyl sulfoxide-water mixtures

The electrochemical kinetics for the oxidation of ferrocenemethanol (FcCH2OH) over the whole composition range of dimethyl sulfoxide (DMSO)-water solutions of different viscosities (I¡¤) containing 50.0 mM (CH3)4NClO4 (TMAP) at a Pt microelectrode was studied using scanning electrochemical microscopy (SECM). The measured diffusion coefficient, DFcCH2OH, as well as the standard rate constant of the heterogeneous electron transfer, k0, as a function of solution composition, showed a minimum at about a DMSO molar fraction (xDMSO) of 0.33, corresponding to the mixture with the maximum solution viscosity. The largest k0 value found, 2.06 A¡À 0.31 cm s-1 in pure water (electrolyte) medium, was about 15 times larger than that obtained in the solution of xDMSO = 0.33 (0.14 A¡À 0.02 cm s-1). A good linear correlation between ln k0 and ln I¡¤ was observed within the solution composition range of 0.10 a?? xDMSO a?? 0.60. An excellent linear correlation between ln k0 and ln I?L, the longitudinal relaxation time, was also obtained with a slope equal to 1.0 when xDMSO = 0-0.60. Unusually small rate constants found in the solutions of xDMSO a?£¤ 0.70 were attributed to adsorption effects at the tip and the substrate electrode. The k0 obtained for the present system was generally found to be inversely proportional to the viscosity of the solution and directly proportional to the diffusion coefficient of the electroactive species.

Miniature Gigahertz Acoustic Resonator and On-Chip Electrochemical Sensor: An Emerging Combination for Electroanalytical Microsystems

Performance of electroanalytical lab-on-a-chip devices is often limited by the mass transfer of electroactive species toward the electrode surface, due to the difficulty in applying external convection. This article describes the powerful signal enhancement attained with a 2.54 GHz miniature acoustic resonator integrated with an electrochemical device in a miniaturized cell. Acoustic resonator and an on-chip gold thin-film three-electrode electrochemical cell were arranged facing each other inside a structured poly(methyl methacrylate) chamber. Cyclic voltammetric and chronoamperometric responses of 1 mM ferrocene-methanol were recorded under resonator’s actuation at powers ranging from 0 to 1 W. Finite element analysis was carried out to study the sono-electroanalytical process. Acoustic resonator’s actuation greatly enhances the mass transport of electroactive species toward the electrode surface. The diffusion limited cyclic voltammetric and chronoamperometric currents increase around 10 and 20 times, respectively, with an input power of 1 W compared to those recorded under stagnant conditions. The improvement in electroanalytical process is mainly associated with acoustic resonator’s vibration induced fluid streaming. The advantages of a miniaturized acoustic resonator, including the submillimeter small size, amenability for mass fabrication, cost effectiveness, low energy consumption, as well as outstanding enhancement of coupled electrochemical processes, will enable the production of highly sensitive compact electroanalytical devices.
