Electrically transmissive alkyne-anchored monolayers on gold

Well-ordered, tightly-packed (surface coverage 0.97 ¡Á 10-9 mol cm-2) monolayer films of 1,4-bis((4-ethynylphenyl)ethynyl)benzene (1) on gold are prepared via a simple self-assembly process, taking advantage of the ready formation of alkynyl C-Au sigma-bonds. Electrochemical measurements using [Ru(NH3)6]3+, [Fe(CN)6]3-, and ferrocenylmethanol [Fe(eta5-C5H4CH2OH)(eta5-C5H5)] redox probes indicate that the alkynyl C-Au contacted monolayer of 1 presents a relatively low barrier for electron transfer. This contrasts with monolayer films on gold of other oligo(phenylene ethynylene) derivatives of comparable length and surface coverage, but with different contacting groups. Additionally, a low voltage transition (Vtrans = 0.51 V) from direct tunneling (rectangular barrier) to field emission (triangular barrier) is observed. This low transition voltage points to a low tunneling barrier, which is consistent with the facile electron transport observed through the C-Au contacted self-assembled monolayer of 1.

Emerging pnictogen-based 2D semiconductors: Sensing and electronic devices

Pnictogens are an intensively studied group of monoelemental two-dimensional materials. This group of elements consists of phosphorus, arsenic, antimony, and bismuth. In this group, the elements adopt two different layered structural allotropes, orthorhombic structure with true van der Waals layered interactions and rhombohedral structure, where covalent interactions between layers are also present. The orthorhombic structure is well known for phosphorus and arsenic, and the rhombohedral structure is the most thermodynamically stable allotropic modification of arsenic, antimony, and bismuth. Due to the electronic structure of pnictogen layers and their semiconducting character, these materials have huge application potential for electronic devices such as transistors and sensors including photosensitive devices as well as gas and electrochemical sensors. While photodetection and gas sensing applications are often related to lithography processed materials, chemical sensing proceeds in a liquid environment (either aqueous or non-aqueous) and can be influenced by surface oxidation of these materials. In this review, we explore the current state of pnictogen applications in sensing and electronic devices including transistors, photodetectors, gas sensors, and chemical/electrochemical sensors.

Synthesis of versatile intermediates of the ferrocene series: Reductive amination of ferrocenecarbaldehyde

Reductive amination of ferrocenecarbaldehyde with several primary and secondary amines in the presence of sodium triacetoxyborohydride was studied. This method was used for the synthesis of new ferrocenylmethylamines, viz., N-(ferrocenylmethyl)isoleucine methyl ester, N,N-bis(ferrocenylmethyl)glycine ethyl ester, and N-(3,5-dibenzyloxybenzyl)-N-(ferrocenylmethyl)methylamine. The latter is a potential precursor of a dendrimer with the chiral ferrocenyl plane in the core.

Ylide Complexes of Alkali and Earth Alkaline Metals, VI. Neutral and Anionic Ferrocenylmethylides and Fluorenylides

Coordination properties of phosphorus ylides towards electropositive metals are greatly improved in systems, where the carbanionic charge can be delocalized into the aromatic rings of substituents, as illustrated in the title compounds.The ferrocenyl-substituted ylide 2, synthesized from bis(diphenylphosphino)methane and (ferrocenyl)trimethylammonium iodide via the phosphonium salt intermediate 1, is thus easily converted into the alkali complexes 3a, b on treatment with NaNH2 or KH in tetrahydrofuran, respectively.The intensely coloured products are soluble in a number of organic solvents.NMR spectra of these solutions provide evidence for an interaction between alkali cations and the ferrocenyl rings. – From (C6H5)2CH2P(C6H5)2 and ferrocenylmethyl chloride a diquaternary salt 4 is obtained, which yields a double-ylide mixture 5a, b on treatment with base.Hydrolysis of this product affords the ylidic phosphine oxide 6. – The reaction of the ylides 7 and 9 (described previously) with NaNH2, KH or barium metal (in liquid ammonia) leads to the (earth) alkali complexes 8a-c and 10a, b, respectively.With the exception of 8c, but similar to 3a, these materials contain tetrahydrofuran solvate molecules.The 23Na NMR spectrum of 8a and the pronounced quadrupole broadening of the P(III) signals by the alkali cations in the 31P NMR spectra of 8a, b allow structural suggestions for the solution state as proposed in the formulae.Further treatment of 10b with KH yields a potassium complex 11, characterized, i.a., via a corresponding diquaternary salt 12. – Keywords: Ylides, Alkali Complexes, Phosphonium Salts, Phosphonium Ferrocenylmethylides

Reagentless recycling of pyruvate oxidase on a conducting polymer-modified electrode

The enzyme pyruvate oxidase (PyOD) covalently immobilized on an original conducting copolymer poly(5-hydroxy-1,4-naphthoquinone-co-5-hydroxy-3-thioacetic-1,4-naphthoq uinone acid) can be recycled under anaerobic conditions, at +0.1 V versus SCE. It is first demonstrated that the quinone group is an efficient co-substrate for PyOD in homogeneous conditions, then this efficiency is preserved when the quinone group is embedded in the polymer structure. The copolymer remains efficient even in aerated media. The low working potential avoids side-oxidations of interfering species as ascorbic acid or salycilate.

Novel method for rapid toxicity screening of magnetic nanoparticles

Iron oxide nanoparticles have attracted a great deal of research interest and have been widely used in bioscience and clinical research including as contrast agents for magnetic resonance imaging, hyperthermia and magnetic field assisted radionuclide therapy. It is therefore important to develop methods, which can provide high-throughput screening of biological responses that can predict toxicity. The use of nanoelectrodes for single cell analysis can play a vital role in this process by providing relatively fast, comprehensive, and cost-effective assessment of cellular responses. We have developed a new method for in vitro study of the toxicity of magnetic nanoparticles (NP) based on the measurement of intracellular reactive oxygen species (ROS) by a novel nanoelectrode. Previous studies have suggested that ROS generation is frequently observed with NP toxicity. We have developed a stable probe for measuring intracellular ROS using platinized carbon nanoelectrodes with a cavity on the tip integrated into a micromanipulator on an upright microscope. Our results show a significant difference for intracellular levels of ROS measured in HEK293 and LNCaP cancer cells before and after exposure to 10 nm size iron oxide NP. These results are markedly different from ROS measured after cell incubation with the same concentration of NP using standard methods where no differences have been detected. In summary we have developed a label-free method for assessing nanoparticle toxicity using the rapid (less than 30 minutes) measurement of ROS with a novel nanoelectrode.
