An amperometric biosensor based on lactate oxidase immobilized in laponite-chitosan hydrogel on a glassy carbon electrode. Application to the analysis of l-lactate in food samples

A biosensor based on the immobilization of lactate oxidase (LOx) on a glassy carbon electrode modified with laponite/chitosan hydrogels for the quantification of l-lactate in alcoholic beverages and dairy products is presented. Ferrocene-methanol (FcMe) is used as artificial mediator. The purpose of this work is to determine the best hydrogel composition from the analytical point of view. The characterization of the hydrogels was carried out by CV, amperometry and EIS. According to permeabilities and charge transfer resistances for ferrocyanide (used as molecular probe) as well as the enzymatic behavior of the enzyme for l-lactate, the best laponite/chitosan mass ratio found was 25/50. The distinct features of the bioelectrode are its long stability, its ability to reject or minimize most interferents including ascorbic acid, and its excellent analytical response, which allowed the reduction of the enzyme content below 0.5 U, for a sensitivity of (0.326 ¡À 0.003) A cm -2 M-1, with a time response lower than 5 s and a detection limit of (3.8 ¡À 0.2) ¡Á 10-6 M. Our l-lactate biosensor was validated by comparison with a standard spectroscopic method.

Synthesis, crystal structures, and electrospray ionisation mass spectrometry investigations of ether- And thioether-substituted ferrocenes

A number of ether- and thioether-substituted ferrocenes (1,1?-bis(1,3-dioxane-2-yl)ferrocene 1, 1,1?-bis(5-methyl-1,3- dioxane-2-yl)ferrocene 2, 1,1?-bis(4-methyl-1,3-dioxane-2-yl)ferrocene 3, 1,1?-bis[(R)-(-)-4-methyl-1,3-dioxane-2-yl]ferrocene 4, 1,1?-bis(4,6-dimethyl-1,3-dioxane-2-yl)ferrocene 5, and 1,1?-bis(1,3-dithiane-2-yl)ferrocene 6) were synthesised by direct condensation of 1,1?-diformylferrocene with the corresponding diols or dithiols. The crystal structures of 1, 5a, 5b, and 6 were determined by X-ray diffraction studies. Electrospray ionisation mass spectrometry was used to investigate the binding behaviour of 1 and 6 toward alkali as well as transition metal cations. The dioxane-containing species 1 showed high affinity toward Li+ and Na+, whereas the dithiane derivative 6 bound, as expected, preferentially to Hg2+. The Royal Society of Chemistry 2003.

Optical Nonlinearities of Organometallic Structures: Aryl and Vinyl Derivatives of Ferrocene

With an objective to understand the nonlinear optical properties of organometallic structures, various aryl and vinyl derivatives of ferrocene were synthesized and their nonlinear optical properties were investigated by using degenerate four-wave mixing.The molecular second hyperpolarizability gamma increases strongly with the length of the conjugated ?-electron system.The results show that effective conjugation is determined predominantly by the length of the aryl-vinyl system; the contribution from the ferrocenyl group is less significant.The d-d resonance of the metal in the ferrocene unit does not appear to make an important contribution to optical nonlinearity.The experimental results on ferrocene are compared with those from a recent theoretical study using semiempirical calculations.Although a qualitative agreement with the theoretical result is found, the experimental value of gamma determined by our method is about 4 times larger.Possible sources of such discrepancies are discussed.

Difluoroacetaldehyde N-Triftosylhydrazone (DFHZ-Tfs) as a Bench-Stable Crystalline Diazo Surrogate for Diazoacetaldehyde and Difluorodiazoethane

Despite the growing importance of volatile functionalized diazoalkanes in organic synthesis, their safe generation and utilization remain a formidable challenge because of their difficult handling along with storage and security issues. In this study, we developed a bench-stable difluoroacetaldehyde N-triftosylhydrazone (DFHZ-Tfs) as an operationally safe diazo surrogate that can release in situ two low-molecular-weight diazoalkanes, diazoacetaldehyde (CHOCHN2) or difluorodiazoethane (CF2HCHN2), in a controlled fashion under specific conditions. DFHZ-Tfs has been successfully employed in the Fe-catalyzed cyclopropanation and Doyle?Kirmse reactions, thus highlighting the synthetic utility of DFHZ-Tfs in the efficient construction of molecule frameworks containing CHO or CF2H groups. Moreover, the reaction mechanism for the generation of CHOCHN2 from CF2HCHN2 was elucidated by density functional theory (DFT) calculations.

Bioencapsulation within synthetic polymers (Part 1): Sol-gel encapsulated biologicals

Since its inception a decade ago, sol-gel encapsulation has opened up an intriguing new way to immobilize biological materials. An array of substances, including catalytic antibodies, DNA, RNA, antigens, live bacterial, fungal, plant and animal cells, and whole protozoa, have been encapsulated in silica, metal-oxide, organosiloxane and hybrid sol-gel polymers. The advantages of these ‘living ceramics’ might give them applications as optical and electrochemical sensors, diagnostic devices, catalysts, and even bioartificial organs. With rapid advances in sol-gel precursors, nanoengineered polymers, encapsulation protocols and fabrication methods, this technology promises to revolutionize bioimmobilization.

Polarization Mechanisms and Properties of Substituted Ferrocenes. A Comparative Study

The polarizability alpha, and second hyperpolarizability, gamma, of some ferrocene derivatives are determined by using an optimized semiempirical approach.The bonding in ferrocene has been investigated through the study of the above polarization properties.The results from the ferrocene derivatives have been correlated with the corresponding substituted benzenes.Scales have been presented, where the derivatives are classified according to their polarization properties.The effect of delocalized ? electrons, charge transfer, and geometry variations on alpha and gamma are commented upon.Selected results of various other properties (e.g., the first hyperpolarizability) are used to demonstrate that some mechanisms (e.g., charge transfer) and changes in geometry may have widely different effects on the molecular properties.Common trends and patterns of behavior are recognized and discussed.The reported results are in good agreement with the experimentally determined ones.

Poly(vinyl ferrocene) redox behavior in ionic liquids

We describe in this report a systematic electrochemical characterization of the ion-solvent coupling mechanisms of poly(vinyl ferrocene) (PVF) in pure ionic liquid (IL) and 0.1 M IL aqueous solutions. Our study showed that the unique solvation and ionic properties of ILs significantly affected the break-in process and the ion-solvent transport mechanisms of PVF redox switching. A square model that emphasized both faradaic and nonfaradaic processes of PVF was used to explain the unique irreversible break-in effect in the pure ILs. The electrochemical quartz crystal microbalance technique was used to characterize the PVF redox processes in 0.1 M 1-butyl-3-methyl imidazolium tetrafluoroborate and 0.1 M methanesulfonate ILs in which an obvious difference of cyclic voltammogram was observed. Our results suggested the existence of strong IL-polymer interaction in 0.1 M methanesulfonate IL solutions, i.e., not only the anions but also the IL molecules interacted with the PVF matrix. The cations were later removed from the PVF matrix to balance the excessive positive charge in PVF oxidation. Our study confirmed that IL was not only an electrolyte but also a solvent in PVF redox switching processes. Various types of interactions between PVF and the IL, including dispersion, dipole induction, dipole orientation, hydrogen-bonding, or ionic/charge-charge interactions, could significantly change the PVF redox dynamics. Thus, IL tremendous diversity in structural and chemical properties and their distinctive properties offer us an excellent opportunity to explore IL-polymer interactions and to dynamically control the conductive polymer relaxation processes and their redox switching mechanism for various applications.
