A portable electrochemical platform integrated with a 3D AuNPS/CNTs sponge for point-of-care testing of neurotransmitters

Point-of-care testing (POCT) of neurotransmitters, such as dopamine (DA) and 5-hydroxytryptamine (5-HT), can be used for early diagnosis of neurological diseases. Among various POCT platforms, electrochemical method-based platforms have attracted increasing interest owning to their high detection sensitivity and specificity as well as fast response time. In this work, we developed a portable electrochemical POCT platform for detection of neurotransmitters, which is based on integration of a three-dimensional (3D) gold nanoparticles/carbon nanotubes (AuNPs/CNTs) sponge synthesized by a simple in-situ growth and eco-friendly ice-templating method modified screen-printed electrode with a miniaturized USB electrochemical analyzer. We demonstrated the good performance of the portable electrochemical platform for detection of two typical neurotransmitters, i.e., DA and 5-HT, with detection sensitivities of 1.02 muA muM?1 cm?2 and 0.55 muA muM?1 cm?2, and detection limits of 0.06 muM and 0.30 muM for DA and 5-HT, respectively. We further verified the feasibility and practicability of the platform by simultaneous detection of DA and 5-HT in spiked saliva. The developed portable electrochemical platform provides a simple and user-friendly way for early diagnosis of neurological diseases in the future, especially at point of care.

Synthesis, characterization, and antitumor activities of 1,1?-diacetylferrocene dihydrazone containing phenolic group and its complexes with Pd(II) and Pt(II)

A ferrocenyl ligand was prepared from condensation of 1,1?- diacetylferrocene dihydrazone with salicylaldehyde. The ligand forms 1:1 complexes with Pd(II) and Pt(II) in good yield. Characterization of the ligand and complexes was carried out using elemental analysis, infrared study, 1H and 13C nuclear magnetic resonance, and electronic absorption spectra. Anticancer activity of the prepared ligand and its complexes against human breast cancer cell line MCF-7 was determined, and the results were compared with the activity of the commonly used anticancer drug cisplatin. The results suggested that the prepared compounds possess significant antitumor activity comparable to the activity of cisplatin.

Adsorption phenomena in systems containing complexes of cucurbit[7]uril with organic compounds

The aim of this study is to consider the adsorption phenomena at the electrode/solution interface in systems containing complexes of cucurbit[7]uril (CB7) with organic compounds: adamantanol?1, ferrocene and organic dye 3,3??diethylthiocarbocyanine iodide. These guests form exclusively stable inclusive complexes with CB7. Experimental dependences of differential capacitance C as a function of potential were used in calculating the adsorption parameters characterizing the most important properties of adsorption layers formed by compounds under study at the electrode/solution interface. For all the systems studied here, as for those studied earlier, adsorption parameters for negative and positive charges of the electrode surface differ. Obviously this points to deep changes in the properties of adsorption layers depending on the electrode potential.

Ferrocene-Linkage-Facilitated Charge Separation in Conjugated Microporous Polymers

Conjugated microporous polymers (CMPs) have full access to the organic synthesis toolbox and feature-rich functionality, structural diversity, and high surface area. We incorporated ferrocene (Fc) into the backbones of CMPs and systematically engineered their optical energy gaps. Compared with the CMPs without Fc units yet adopting a similar molecular orbital level, Fc-based CMPs can sufficiently generate reactive oxygen species (ROS) under visible light. The resultant ROS are able to effectively decompose the absorbed pollutants, including organic dyes and chemical warfare agents. Specifically, Fc-based CMPs significantly outperform commercial TiO2 (P25) in the degradation of methylene blue and are capable of converting 2-chloroethyl ethyl sulfide (a mustard gas simulant) into a completely nontoxic product.

Ferrocenyl oligo(phenylene-vinylene) thiols for the construction of self-assembled monolayers

A short and efficient preparation of conjugated oligo(phenylene-ethylene) thiols bearing redox-active ferrocene moieties is described. While minimising the number of synthetic steps, the proposed strategy permits the development of sets of oligomers with varying chain length. The redox properties of the compounds in solution are determined. Preliminary studies of self-assembled monolayers (SAMs) on gold electrodes are discussed, and indicate that electron transfer through the SAMs is indeed rapid. Wiley-VCH Verlag GmbH & Co.

Preparation, coordination and catalytic use of planar-chiral monocarboxylated dppf analogues

A novel polar dppf derivative possessing only planar chirality, 1?,2-bis(diphenylphosphino)-ferrocene-1-carboxylic acid (Hdpc), has been synthesised in racemic form and resolved into enantiomers via esters with d-glucose diacetonide ((Rp)- and (Sp)-3). (R p)-Hdpc was further converted to a series of N-substituted amides that were studied as ligands for Pd-catalysed enantioselective allylic alkylation of racemic (E)-1,3-diphenylprop-2-en-1-yl acetate or ethyl carbonate with malonate esters, showing high activity and good enantioselectivity (er up to 10: 90). The catalytic results were correlated with the structural data (X-ray diffraction and solution NMR) for (eta3-allyl)palladium(ii) complex (Rp)-[Pd(eta3-1,3-Ph2C 3H3){Fe(eta5-C5H 3-1-(C(O)NHCH2Ph)-2-(PPh2-kappaP)) (eta5-C5H4PPh2-kappaP)}]ClO 4 (16) as a model of the plausible reaction intermediate. A further study into the coordination properties of Hdpc led to isolation of chelate complex [PdCl2(Hdpc-kappa2P,P?)] (12). The crystal structures of rac-Hdpc, methyl ester of (Rp)-Hdpc, glycoside (R p)-3, and 12¡¤Me2CO suggested a close structural relationship between dppf and Hdpc.

Synthesis of alpha-arylalkylferrocenes through cesium fluoride-promoted coupling of arylboronic acids with N-tosylhydrazones

A cesium fluoride-promoted reductive coupling reaction of acylferrocene tosylhydrazones with arylboronic acids has been developed, producing highly substituted alpha-arylalkylferrocenes in moderate to excellent yields. The reaction employs anionic fluorine to facilitate the cleavage of C?B bond. The developed methodology demonstrates a wide substrate scope and high functional groups tolerance. Moreover, the alpha-arylalkylferrocenes compounds were also obtained on a multi-gram scale.
