The diiron bridging vinyliminium complexes [Fe2{mu- eta1:eta3-C=N(Me)2C(R?)=C(R?)} (mu-CO)(CO)(Cp)2][SO3CF3] (R? = H, R? = SiMe3, 3a; R? = H, R? = Tol =4-MeC 6H4, 3b; R? = Me, R? = Me, 3c; R? = SPh, R? = Me, 3d; R? = H, R? = Fc = [Fe(C5H 4)(Cp)], 6e) react with propargyl alcohol (HC?CCH 2OH), in refluxing toluene, affording the polysubstituted ferrocenes as mixtures of two isomeric forms: [1-NMe2-2-R?-3-R?-5- CH2OCH2C?CH-Fc] (R? = H, R? = SiMe 3, 6a; R? = H, R? = Tol, 6b; R? = Me, R? = Me, 6c; R? = SPh, R? = Me, 6d, R? = H, R? = Fc, 6e) and [1-NMe2-2-R?-3-R?-4-CH2OCH2C? CH-Fc] (R? = H, R? = SiMe3, 7a; R? = H, R? = Tol, 7b; R? = Me, R? = Me, 7c; R? = SPh, R? = Me, 7d) in overall yields of about 55-65%. Formation of the functionalized cyclopentadienyl in the ferrocene products takes place through the assembly of two propargyl units with the bridging vinyliminium ligand: one alkynol is incorporated by a [3 + 2] cycloaddition with the bridging C3 ligand; a second alkynol unit gives rise to a pendant chain through -OH substitution. Investigations show that the substitution step is catalyzed by the parent diiron complex itself or by a mononuclear iron fragment (likely the Fp+ complex). The pendant propargyl chain has been exploited to connect the ferrocene to other molecular fragments: in particular, the reaction of 6a with 4-biphenyl azide, by copper-catalyzed azide-alkyne cycloaddition (CuAAC), leads to the formation of the triazole-functionalized ferrocene [1-NMe 2-2-CH2OCH2-N3(C6H 4Ph)C2H-4-SiMe3-Fc] (12). Moreover, 6a reacts with Co2(CO)8, affording the complex [Co 2{mu-eta2-HC?CR}(CO)6] (13), (HC?CR = 6a), where the alkyne adopts a eta2 coordination to a dicobalt hexacarbonyl fragment. The molecular structure of 7a has been determined by X-ray diffraction studies.

A dual-stream flow injection method has been developed for electrochemical detection of ferrocene derivatives in flow streams. The method is based on a previously described electrochemical amplification method in which currents for analyte oxidation are enhanced by rapid analyte regeneration via a solution-phase electron exchange reaction with a sacrificial reagent. The use of two independent flow channels in the present method, one to carry the analyte and another to supply the sacrificial reagent, eliminates the necessity of spiking samples and calibration standards with sacrificial reagent to avoid injection transients. Hydrodynamic voltammograms were recorded for a series of injections of hydroxymethylferrocene (HMFc, a model ferrocene analyte) into the carrier stream in the presence and absence of ferrocyanide (which serves as sacrificial reagent) in the reagent stream. From these voltammograms an optimum detection potential for HMFc of +0.8 V versus Ag|AgCl|KClsat was selected. Two different concentrations of sacrificial reagent were tested for a range of HMFc concentrations between 1 × 10-3 and 1 × 10-8 M for which both unamplified and amplified peaks could be detected. An amplification factor of approximately 300 was obtained for a 1 × 10-8 M HMFc injection with 2 × 10-4 M ferrocyanide present in the reagent stream.

Organometallic Ru(II)-cymene complexes linked to ferrocene (Fc) via nitrogen heterocycles have been synthesized and studied as cytotoxic agents. These compounds are analogues of Ru(II)-arene piano-stool anticancer complexes such as RAPTA-C. The Ru center was coordinated by pyridine, imidazole, and piperidine with 0-, 1-, or 2-carbon bridges to Fc to give six bimetallic, dinuclear compounds, and the properties of these complexes were compared with their non-Fc-functionalized parent compounds. Crystal structures for five of the compounds, their Ru-cymene parent compounds, and an unusual trinuclear compound were determined. Cyclic voltammetry was used to determine the formal MIII/II potentials of each metal center of the Ru-cymene-Fc complexes, with distinct one-electron waves observed in each case. The Fc-functionalized complexes were found to exhibit good cytotoxicity against HT29 human colon adenocarcinoma cells, whereas the parent compounds were inactive. Similarly, antibacterial activity from the Ru-cymene-Fc compounds was observed against Bacillus subtilis, but not from the unfunctionalized complexes. In both cases, the IC50 values correlated quantitatively with the Fc+/0 reduction potentials. This is consistent with more facile oxidation to give ferrocenium, and subsequent generation of toxic reactive oxygen species, leading to greater cytotoxicity. The antioxidant properties of the complexes were quantified by a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. EC50 values indicate that linking of the Ru and Fc centers promotes antioxidant activity.

A sustainable and green route to access diverse functionalized ketones via dehydrogenative?dehydrative cross-coupling of primary and secondary alcohols is demonstrated. This borrowing hydrogen approach employing a pincer N-heterocyclic carbene Mn complex displays high activity and selectivity. A variety of primary and secondary alcohols are well tolerant and result in satisfactory isolated yields. Mechanistic studies suggest that this reaction proceeds via a direct outer-sphere mechanism and the dehydrogenation of the secondary alcohol substrates plays a vital role in the rate-limiting step.

MicroRNAs (MiRNAs) have been regarded as clinically important biomarkers and drug discovery targets. In this work, we reported a simple and ultrasensitive electrochemical method for miRNAs detection based on single enzyme amplification and electrochemical-chemical-chemical (ECC) redox cycling. Specifically, upon contact with the target miRNAs, the hairpin structure of biotinylated DNA immobilized on gold electrode was destroyed and the biotin group in DNA was forced away from the electrode surface, allowing for the coupling of streptavidin-conjugated alkaline phosphatase (SA-ALP). Then, ascorbic acid (AA, the enzymatic product of ALP) triggered the ECC redox cycling with ferrocene methanol (FcM) and tris(2-carboxyethyl)phosphine (TCEP) as the redox mediator and the chemical reducing reagent, respectively. The method was more sensitive than that with horseradish peroxidase (HRP) or glucose oxidase (GOx) triggered recycling since one ALP molecule captured by one target miRNA molecule promoted the production of thousands of AA. Analytical merits (e.g., detection limit, dynamic range, specificity, regeneration and reproducibility) were evaluated. The feasibility of the method for analysis of miRNA-21 in human serum has also been demonstrated.

Soluble amyloid-beta oligomer (AbetaO) is believed to be a reliable molecular biomarker for the diagnosis of Alzheimer’s disease (AD) because of its high toxicity for neuronal synapse and higher concentration level in cerebrospinal fluid sample from AD patient than from control individual. At present, it is critical to develop a simple method for AbetaO detection with low cost as well as high sensitivity and selectivity. In this work, we reported an antibody-free electrochemical method for the detection of AbetaO based on the specific interaction between AbetaO and PrP(95-110) peptide, a segment of cellular prion protein. Specifically, cysteine-containing PrP(95-110) peptide was first immobilized on a gold electrode for the capture of AbetaO. Then, alkaline phosphatase-conjugated PrP(95-110) was used for the recognition of the captured AbetaO and the generation of electroactive species. Furthermore, an “outer-sphere to inner-sphere” electrochemical-chemical-chemical (ECC) redox cycling using ferrocene methanol as the redox mediator was employed to enhance the detection sensitivity. As a result, a detection limit of 3 pM for equivalent monomer was achieved. The amenability of this method to AbetaO analysis in a biological matrix was demonstrated by assays of AbetaO in serum samples.

The design and operation of biosensors is not trivial. For instance, variation in the output signal during monitoring of analytes can not usually be controlled. Hence, if such control were possible, and could be triggered on demand, it would greatly facilitate system design and operation. Herein, we report the design of two types of voltamperometric immunosensors, in which the magnitude of the current output signal (differential pulse voltammetry [DPV]) can be increased or decreased as needed. The designed systems use monoclonal and polyclonal anti-human IgG antibodies, conjugated to monopodal ferrocene-modified gold nanoparticles that are casted onto screen-printed carbon electrodes (Ab/mFcL/AuNPs/SPCEs). Upon addition of human IgG as antigen, the systems exhibit opposite responses according to the Ab: the current decreases when monoclonal Ab is used, whereas it increases when polyclonal Ab is used. We attributed the former response to inhibition of electron-transfer (due to the formation of a protein layer), and the latter response, to a global increase in electron transfer (induced by the aggregation of gold nanoparticles). These effects were confirmed by studying a custom-made lipoic acid-based bipodal ligand, which confirmed that the increase in current is effectively induced by the aggregation of the modified nanoparticles (pAb/mFcL/AuNPs). Both sensors have large dynamic ranges, although the pAb-based one was found to be 3.3-times more sensitive. Tests of selectivity and specificity for ovalbumin, alpha-lactalbumin and serum bovine albumin showed that the immunosensors are highly selective and specific, even in the presence of up to 1000-fold levels of potentially competitive proteins. The limit of detection for human IgG using the pAb/mFcL/AuNP bioconjugate was estimated to be 0.85 ng/mL. The pAb/mFcL/AuNPs-based biosensor has used to determine amounts of human IgG in real sample.

A new method was introduced to research the corrosion resistance of enamel coatings which were sintered at different temperatures in this paper.1-4 Scanning electrochemical microscopy (SECM) conjunction with capacitance-potential test and Mott-Schottky analysis technique were used to study the coating failure process and semiconductor conduction behavior of enamel coating in 3.5wt.% NaCl solution. The high strength steel (SAPH440) was selected as the metal substrate. The coatings which were sintered at different temperatures on the high strength steel were analyzed and their corrosion behaviors and microstructures were also measured by potentiodynamic polarization curves, Mott-Schottky analysis technique and scanning electrochemical microscopy.5-10 In this paper, five kinds of enamel coatings were prepared on high strength steel. The SECM results show that the Faraday current of the microprobe tip gradually decreases with the soaking time increasing, which indicates that the coatings become failure slowly with the invasion of water and aggressive ions. At the same time, the tip current was homogeneous during the immersion process, which reflected that the surface of the sample remained stable, no obvious bulges appeared. Capacitance-potential test and Mott-Schottky analysis7,8 show that the external ions and water molecules gradually penetrate into the coating; coating showed characteristics of n-type semiconductor as time increases, the capacitance increases gradually, the space charge layer thickness decreases, slope of Mott-Schottky curve decreased gradually which indicates that the failure of coating in the process of soaking slowly with the charge carrier density increases.

Electrochemical potential cycling of gold electrodes in commonly used redox active species to produce a nanostructured surface is introduced. A commercially available gold electrode when cycled in three redox active species including hexaammine ruthenium chloride, ferrocene methanol and ferricyanide shows rapid conversion of the surface into a nanostructured form within 50 cycles which usually requires hundreds of cycles in their absence. The active gold nanostructured electrode was characterized by cyclic voltammetry in acidic and alkaline electrolyte indicating the presence of different basal sites depending on the redox species employed. In addition, the active gold nanostructured surface shows higher electrocatalytic activity than the pristine polycrystalline gold electrode for glucose and ascorbic acid oxidation in alkaline media.
