Problems analysis and new fabrication strategies of mediated electrochemical biosensors for wastewater toxicity assessment

Conventional mediated electrochemical biosensors for toxicity assessment were almost based on ?one-pot? principle, i.e., mediators and the under-test chemicals were mixed together in the same vessel. In this process, the electron mediator is assumed to be merely an electron acceptor and cannot react with under-test toxicants. Actually?some under-test pollutants (such as metal ions) could react with the electron mediators, thus affecting the detection accuracy and sensitivity of the sensors. It was also found that at least two other interference factors have been ignored in present?one-pot? mediated electrochemical biosensor systems, i.e., (1) the electrochemical sensitivity of mediators to pH; and (2) the potential reactions between under-test chemicals and buffers and the consequent pH changes. In this study, the three ignored interference factors have been investigated systematically and demonstrated by significance tests. Moreover, a solving strategy, an isolation method, is proposed for fabrication of novel mediated electrochemical biosensor to avoid the interference factors existing at present mediated electrochemical biosensor. According to the testing results obtained from the isolation method, IC50 values of Cu2+, Cd2+, Zn2+, Fe3+, Ni2+ and Cr3+ were 21.3 mg/L, 3.7 mg/L, 26.7 mg/L, 4.4 mg/L and 10.7 mg/L, respectively. The detection results of four real water samples also suggested this method could be applied for the practical and complex samples.

Cyclodextrin Films with Fast Solvent Transport and Shape-Selective Permeability

This study describes the molecular-level design of a new type of filtration membrane made of crosslinked cyclodextrins?inexpensive macrocycles of glucose, shaped like hollow truncated cones. The channel-like cavities of cyclodextrins spawn numerous paths of defined aperture in the separation layer that can effectively discriminate between molecules. The transport of molecules through these membranes is highly shape-sensitive. In addition, the presence of hydrophobic (cavity) and hydrophilic (ester-crosslinked outer part) domains in these films results in high permeances for both polar and nonpolar solvents.

A convenient method for synthesis of novel alkylferrocene derivatives with various functional groups: synthesis, characterization and electrochemical investigation

Abstract: In this research, new ferrocenylmethylesters were synthesized according to esterification reaction. To reach this purpose, direct and indirect esterification methods were used. Indirect method included Cannizzaro reaction of new alkylferrocenecarboxaldehydes result in production of alkylferrocenecarboxylic acids and alkyl(hydroxymethyl)ferrocene derivatives. Finally, a variety of known procedures were used for converting the new alkylferrocenecarboxylic acids to the corresponding esters. The oxidative esterification reaction was accomplished using K2CO3/I2 as oxidant in the direct method. The advantages of this method are one-pot and single-step reaction and remarkably high total yield of this procedure. The chemical structures were confirmed with FT-IR, 1H NMR, 13C NMR and MASS spectroscopy as well as CHN analysis. Electrochemical behavior of synthesized compounds was studied by cyclic voltammetry, and the relationship between the peak currents and the square root of the scan rate showed that the redox process is diffusion-limited.

Voltammetric Determination of Arsenic with Modified Glassy Carbon Electrode

In this study, glassy carbon electrode modified with nano gold-crystal violet film has been used to detect arsenite (As (III)) in a model system and in groundwater samples. The modified electrode was characterized by scanning electrochemical microscopy (SECM) and electrochemical impedance spectroscopy (EIS). Using voltammetric measuring technique, linear response was obtained in a concentration range of 2.0?22.0 muM. The arsenite concentrations in groundwater samples varied between 2.4 muM to 4.8 muM. The sensitivity of the modified electrode for As (III) detection was 5.6 muA/muM cm2 and 0.8 muM concentration was found as lower limit of detection (LOD). The accuracy of the method was checked with standard method anodic stripping voltammetry (ASV). Groundwater samples were characterized with dynamic (DLS) and electrophoretic (ELS) light scattering measurements which have shown that particles present in different samples differ in size distribution and zeta potential which did not interfere with As (III) detection.

Nonbifunctional Outer-Sphere Strategy Achieved Highly Active alpha-Alkylation of Ketones with Alcohols by N-Heterocyclic Carbene Manganese (NHC-Mn)

The unusual nonbifunctional outer-sphere strategy was successfully utilized in developing an easily accessible N-heterocyclic carbene manganese (NHC-Mn) system for highly active alpha-alkylation of ketones with alcohols. This system was efficient for a wide range of ketones and alcohols under mild reaction conditions, and also for the green synthesis of quinoline derivatives. The direct outer-sphere mechanism and the high activity of the present system demonstrate the potential of nonbifunctional outer-sphere strategy in catalyst design for acceptorless dehydrogenative transformations.

On-chip electrophoresis in supported lipid bilayer membranes achieved using low potentials

A micro supported lipid bilayer (SLB) electrophoresis method was developed, which functions at low potentials and appreciable operating times. To this end, (hydroxymethyl)-ferrocene (FcCH2OH) was employed to provide an electrochemical reaction at the anode and cathode at low applied potential to avoid electrolysis of water. The addition of FcCH2OH did not alter the SLB characteristics or affect biomolecule function, and pH and temperature variations and bubble formation were eliminated. Applying potentials of 0.25-1.2 V during flow gave homogeneous electrical fields and a fast, reversible, and strong build-up of a charged dye-modified lipid in the direction of the oppositely charged electrode. Moreover, streptavidin mobility could be modulated. This method paves the way for further development of analytical devices.

Using hydrazine to link ferrocene with Re(CO)3: A modular approach

Acetyl ferrocene and diacetyl ferrocene both readily react with an excess of hydrazine to afford the corresponding hydrazone compounds. These compounds can then be linked to Re(CO)3 via a metal-mediated Schiff base reaction, resulting in a series of ferrocene-Re(CO)3 conjugates with different stoichiometries. Conjugates with 1:1, 1:2, and 2:1 ferrocene: Re(CO)3 ratios can be produced via this “modular” type synthesis approach. Several examples of these conjugates were structurally characterized, and their spectroscopic, electrochemical, and spectroelectrochemical behaviors were investigated. The electronic structures of these compounds were also probed using DFT and TDDFT calculations.

Spectral response to oxy-anions based on ferrocenylphalene

A series of ferrocenyl derivatives (1, 2, 3 and 4) containing phenol group, chemosensors for anions, have been synthesized and optimized. Their binding ability for various anions (F-, Cl-, Br-, I-, AcO- and H2PO4-) were evaluated by theoretical investigation, UV-Vis, 1H NMR titration and cyclic voltammetry experiments and these chemosensors showed strong binding ability for oxy-anions. Theoretical investigation analysis revealed the substituent was different, the space structure was different. And the intramolecular hydrogen bond existed between -OH and other atoms in the structure of these compounds. UV-Vis titrations indicated the anion binding abilities could be tuned by electron push-pull properties of the substituents on the phenyl ortho or para position. Electrochemical titrations showed the addition of anions led to the weak of redox response and the oxidation peak potential moved to more positive potential gradually. In addition, these chemosensors were sensitive to the AcO- detection without the interference of other anions studied, as well as chemosensor 4 was sensitive to the H2PO4- detection.

Host-Guest-Induced Electron Transfer Triggers Radical-Cation Catalysis

Modifying the reactivity of substrates by encapsulation is a fundamental principle of capsule catalysis. Here we show an alternative strategy, wherein catalytic activation of otherwise inactive quinone “co-factors” by a simple Pd2L4 capsule promotes a range of bulk-phase, radical-cation cycloadditions. Solution electron-transfer experiments and cyclic voltammetry show that the cage anodically shifts the redox potential of the encapsulated quinone by a significant 1 V. Moreover, the capsule also protects the reduced semiquinone from protonation, thus transforming the role of quinones from stoichiometric oxidants into catalytic single-electron acceptors. We envisage that the host-guest-induced release of an “electron hole” will translate to various forms of non-encapsulated catalysis that involve other difficult-to-handle, highly reactive species.

Synthesis of Diferrocenyl Hydrazone?Enone Receptor Molecules ? Electronic Communication, Metal Binding, and DFT Study

Four new diferrocenyl hydrazone?enone compounds were obtained through a two-step reaction process involving 1,1?-diacetylferrocene, hydrazides, and ferrocenecarboxaldehyde. The structural characterization of two compounds, 6 and 7, through single-crystal X-ray diffraction showed the presence of a stable eclipsed conformation with the two ferrocenyl moieties oriented in trans geometries. The electrochemical and metal-ion sensing properties of the diferrocenyl-bifunctionalized compounds were explored to understand their potential in electronic communication and as receptor molecules. Compounds 1,1?-[(eta5-C5H5)Fe(eta5-C5H4)CH=CHC(O)(eta5-C5H4)Fe{(eta5-C5H4)C(CH3)=N?N(H)C(O)?R}] [R = C6H4OH (6), C6H4N-p (7)], showed selective interactions with Pb2+cations and distinct binding interactions with bovine serum albumin (BSA) protein. The mode of the metal?receptor interaction was established through DFT studies. The redox properties of the diferrocenyl compounds with variable end groups revealed distinct electronic communication between the two electroactive groups.
