Highly sensitive conductometric biosensors for total lactate, D- and L-lactate determination in dairy products

An original method combining two conductometric biosensors is proposed for the determination of total lactate, L- and D-lactate in dairy products. The biosensors were prepared through cross-linking of L-lactate oxidase from Pediococcus sp. (LODP) or a combination of LODP and horseradish peroxidase (HRP) at the surface of gold interdigitated microelectrodes using glutaraldehyde (GA) vapors. LODP is reported to catalyze specifically L-lactate oxidation into pyruvate and hydrogen peroxide in solution. In this work, we showed that LODP chiral selectivity was lost following enzyme cross-linking, rendering LODP sensor suitable for total lactate determination. Biosensor sensitivity towards both stereoisomers was 1.16 ¡À 0.04 muS muM-1. The addition of HRP significantly improved the linear range and stability of LODP biosensor, but also increased its sensitivity, the effect being more pronounced for D-lactate (+381%) than for L-lactate (+260%). This result was attributed to a modification in LODP chiral selectivity combined with the production of additional ions (acetate, H+ and HCO3-) via the HRP-catalyzed oxidation of pyruvate. A method, taking advantage of the difference in D- and L-lactate behaviours and combining the monoenzymatic and bienzymatic biosensors calibration data, was proposed for the calculation of their concentrations in unknown samples. Different parameters (HRP/LODP ratio, exposure time to GA vapors, pH and concentration of measurement medium) were optimized in order to achieve the best compromise between sensitivity and stability of the biosensors. The best limit of detection for L- and D-lactate, calculated as three times the signal to noise ratio was achieved with the bi-enzymatic sensor and was equal to 0.05 muM. LODP/HRP biosensor response towards L-lactate was not significantly affected by glucose, fructose and lactose. The proposed biosensors were finally applied to the determination of total lactate, D- and L-lactate concentrations in yogurt samples. Results were in good agreement with those obtained using a reference colorimetric enzymatic method.

Diamond nanoparticles as a way to improve electron transfer in sol-gel l-lactate biosensing platforms

In the present work, we have included for the first time diamond nanoparticles (DNPs) in a sol-gel matrix derived from (3-mercaptopropyl)-trimethoxysilane (MPTS) in order to improve electron transfer in a lactate oxidase (LOx) based electrochemical biosensing platform. Firstly, an exhaustive AFM study, including topographical, surface potential (KFM) and capacitance gradient (CG) measurements, of each step involved in the biosensing platform development was performed. The platform is based on gold electrodes (Au) modified with the sol-gel matrix (Au/MPTS) in which diamond nanoparticles (Au/MPTS/DNPs) and lactate oxidase (Au/MPTS/DNPs/LOx) have been included. For the sake of comparison, we have also characterized a gold electrode directly modified with DNPs (Au/DNPs). Secondly, the electrochemical behavior of a redox mediator (hydroxymethyl-ferrocene, HMF) was evaluated at the platforms mentioned above. The response of Au/MPTS/DNPs/LOx towards lactate was obtained. A linear concentration range from 0.053 mM to 1.6 mM, a sensitivity of 2.6 muA mM-1 and a detection limit of 16 muM were obtained. These analytical properties are comparable to other biosensors, presenting also as advantages that DNPs are inexpensive, environment-friendly and easy-handled nanomaterials. Finally, the developed biosensor was applied for lactate determination in wine samples.

Semiconductor Property and Corrosion Behavior of Passive Film Formed on Steel with Zinc Coating in 5% NaCl Solution

The initial stage of corrosion behavior and the semiconductor property of a passive film formed on steel with zinc coating were investigated in 5?wt.% NaCl solution using scanning electrochemical microscopy (SECM), electrochemical impedance spectroscopy (EIS), potential-capacitance measurement and the Mott?Schottky analysis method. The SECM test results reveal that the Faradic currents on the tip of the ultramicro electrode decreased with the extension of immersion time, suggesting that the coating was slowly degrading, and the water and ions gradually permeated into the coating. The tip current remained stable without obvious bursting and swelling, which revealed that no blister occurred inside the coating. EIS results also support the above conclusion, especially for long-term immersion. The potential-capacitance and Mott?Schottky analysis show that the water and ions gradually entered into the coating during the immersion process, while at the same time the coating showed the characteristics of n-type semiconductor. As the time elapsed, the capacitance value decreased and the thickness of the space charge layer declined. The decrease in the slope of the Mott?Schottky curves suggested the simultaneous increase of the carrier density, and the coating was degrading. SEM observation also exhibits an obvious coating degradation after immersion compared with the previous coating without immersion in solution.

Nickel(0)-Catalyzed Hydroalkenylation of Imines with Styrene and Its Derivatives

A nickel(0)-catalyzed hydroalkenylation of imines with styrene and its derivatives is described. A wide range of aromatic and aliphatic imines directly coupled with styrene and its derivatives, thus providing various synthetically useful allylic amines with up to 95 % yield. The reaction offers a new atom- and step-economical approach to allylic amines by using alkenes instead of alkenyl-metallic reagents. Experiments and DFT calculations showed that TsNH2 promotes the proton transfer from the coordinated olefin to the imine, accompanied by a new C?C bond formation.

Improvement of the corrosion resistance of biomedical zr-ti alloys using a thermal oxidation treatment

Binary Zr-Ti alloys spontaneously develop a tenacious and compact oxide layer when their fresh surface is exposed either to air or to aqueous environments. Electrochemical impedance spectroscopy (EIS) analysis of Zr-45Ti, Zr-25Ti, and Zr-5Ti exposed to simulated physiological solutions at 37 C evidences the formation of a non-sealing bilayer oxide film that accounts for the corrosion resistance of the materials. Unfortunately, these oxide layers may undergo breakdown and stable pitting corrosion regimes at anodic potentials within the range of those experienced in the human body under stress and surgical conditions. Improved corrosion resistance has been achieved by prior treatment of these alloys using thermal oxidation in air. EIS was employed to measure the corrosion resistance of the Zr-Ti alloys in simulated physiological solutions of a wide pH range (namely 3 ? pH ? 8) at 37 C, and the best results were obtained for the alloys pre-treated at 500 C. The formation of the passivating oxide layers in simulated physiological solution was monitored in situ using scanning electrochemical microscopy (SECM), finding a transition from an electrochemically active surface, characteristic of the bare metal, to the heterogeneous formation of oxide layers behaving as insulating surfaces towards electron transfer reactions.

Application of Polysaccharide-Based Chiral HPLC Columns for Separation of Nonenantiomeric Isomeric Mixtures of Organometallic Compounds

A series of polysaccharide-based chiral stationary phase (CSP) columns, Daicel Chiralpak IA, IB, and IC, were applied in the separation of the nonenantiomeric isomers of various organometallic compounds and were found to be highly effective in recognizing isomers of minor structural differences. The CSP columns have succeeded to separate the double-bond regioisomers in bridged (eta5-formylcyclopentadienyl)manganese(I) dicarbonyl complexes 1a/1b, the structural isomers of methylbutenylferrocene derivatives in 2a/2b and 3a/3b, and the geometrical isomers of the (2-methyl-2-butenyl)ferrocenes in (Z)/(E)-3b. Due to the close similarity of the isomeric compounds in these mixtures, separations of the components are extremely difficult and could not be attained by conventional methods such as silica gel column chromatography, silica gel HPLC, recrystallization, distillation/sublimation, etc. Clearly, the polysaccharide-based CSP columns have unique advantages in separation/purification technology, and this study has shown potential usefulness of the CSP columns in separation of not only enantiomeric but also nonenantiomeric mixtures.

Responsive Gel-like Supramolecular Network Based on Pillar[6]arene-Ferrocenium Recognition Motifs in Polymeric Matrix

A dual-responsive supramolecular network based on pillar[6]arene-ferrocenium redox-controllable recognition motifs in polymeric backbones is constructed with a ferrocenium-functionalized copolymer and a pillar[6]arene copolymer, in which the first example of pillar[6]arene-functionalized copolymer was synthesized through the reversible addition/fragmentation chain-transfer copolymerization of an acrylate-functionalized pillar[6]arene and methyl acrylate. The resulting supramolecular network exhibits dramatically increased viscosity than the non-cross-linked mixtures and demonstrates a gel-like behavior on macroscale with a transient-network behavior revealed by rheology study. Furthermore, the viscoelastic properties of such supramolecular network can be easily controlled by different external stimuli including redox stimulus and competing host/guest reagents.
