Redox-Triggered Disassembly of Nanosized Liposomes Containing Ferrocene-Appended Amphiphiles

We report a redox-responsive liposomal system capable of oxidatively triggered disassembly. We describe the synthesis, electrochemical characterization, and incorporation into vesicles of an alternative redox lipid with significantly improved synthetic efficiency and scalability compared to a ferrocene-appended phospholipid previously employed by our group in giant vesicles. The redox-triggered disassembly of both redox lipids is examined in nanosized liposomes as well as the influence of cholesterol mole fraction on liposome disassembly and suitability of various chemical oxidants for in vitro disassembly experiments. Electronic structure density functional theory calculations of membrane-embedded ferrocenes are provided to characterize the role of charge redistribution in the initial stages of the disassembly process.

Tackling the Challenges of Enzymatic (Bio)Fuel Cells

The ever-increasing demands for clean and sustainable energy sources combined with rapid advances in biointegrated portable or implantable electronic devices have stimulated intensive research activities in enzymatic (bio)fuel cells (EFCs). The use of renewable biocatalysts, the utilization of abundant green, safe, and high energy density fuels, together with the capability of working at modest and biocompatible conditions make EFCs promising as next generation alternative power sources. However, the main challenges (low energy density, relatively low power density, poor operational stability, and limited voltage output) hinder future applications of EFCs. This review aims at exploring the underlying mechanism of EFCs and providing possible practical strategies, methodologies and insights to tackle these issues. First, this review summarizes approaches in achieving high energy densities in EFCs, particularly, employing enzyme cascades for the deep/complete oxidation of fuels. Second, strategies for increasing power densities in EFCs, including increasing enzyme activities, facilitating electron transfers, employing nanomaterials, and designing more efficient enzyme-electrode interfaces, are described. The potential of EFCs/(super)capacitor combination is discussed. Third, the review evaluates a range of strategies for improving the stability of EFCs, including the use of different enzyme immobilization approaches, tuning enzyme properties, designing protective matrixes, and using microbial surface displaying enzymes. Fourth, approaches for the improvement of the cell voltage of EFCs are highlighted. Finally, future developments and a prospective on EFCs are envisioned.

RAFT-synthesized polymers based on new ferrocenyl methacrylates and electrochemical properties

Herein are reported the synthesis and the full characterization of three new ferrocenyl monomers, namely 2-(ferrocenylmethoxy)ethyl methacrylate (FMOEMA), 3-(ferrocenylmethoxy)propyl methacrylate (FMOPMA) and 4-(ferrocenylmethoxy)butyl methacrylate (FMOBMA), synthesized from ferrocenemethanol. Homopolymers were prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization in toluene at 70C using 2-cyanoprop-2-yl-dithiobenzoate (CPDB) as a chain transfer agent. Polymerization kinetics were compared to those of the well-known 1-ferrocenylmethyl methacrylate (FMMA). The ferrocenyl containing monomers with alkoxy linkers were found to be as reactive as FMMA in RAFT polymerization. Polymers with controlled molar masses with dispersities lower than 1.5 were obtained. The chemical structures of the monomers and polymers were fully characterized by NMR and size exclusion chromatography. Glass transition temperatures of these methacrylic polymers ranged from 36C to 2C when controlling the length of the alkoxy linker between the ferrocene unit and the backbone. The electrochemical properties of the monomers and the homopolymers were demonstrated using cyclic voltammetry.

Oxidative purification of halogenated ferrocenes

We report the large scale syntheses and ‘oxidative purification’ of fcI2, fcBr2 and FcBr (fc = ferrocene-1,1?-diyl, Fc = ferrocenyl). These valuable starting materials are typically laborious to separate via conventional techniques, but can be readily isolated by taking advantage of their increased E1/2 relative to FcH/FcX contaminants. Our work extends this methodology towards a generic tool for the separation of redox active mixtures.

Biphenyl-lithium-TEGDME solution as anolyte for high energy density non-aqueous redox flow lithium battery

Non-aqueous redox flow batteries, because of larger operating voltage, have attracted considerable attention for high-density energy storage applications. However, the study of the anolyte is rather limited compared with the catholyte due to the labile properties of redox mediators at low potentials. Here, we report a new strategy that exploits high concentration organic lithium metal solution as a robust and energetic anolyte. The solution formed by dissolving metallic lithium with biphenyl (BP) in tetraethylene glycol dimethyl ether (TEGDME) presents a redox potential of 0.39 V versus Li/Li+, and a concentration up to 2 M. When coupled with a redox-targeted LiFePO4 catholyte system, the constructed redox flow lithium battery full cell delivers a cell voltage of 3.0 V and presents reasonably good cycling performance.

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.
