“Gentle lithography” with benzene on Si(100)

Nanoscale lithography of small- and medium-sized molecules on a clean silicon surface was studied using benzene. A scanning tunneling microscopy (STM)-based nanolithographic method was also investigated. The patterning areas of the surface with ethylene and vinyl ferrocene was also discussed. It was observed that any molecules that remain unsaturated after adsorption are candidates to form a monolayer template for this kind of lithography.

A biguanide/Pd-decorated SBA-15 hybrid nanocomposite: Synthesis, characterization and catalytic application

A stable palladium-decorated SBA-15 nanocomposite was simply fabricated through surface modification of SBA-15 with biguanide and subsequent metal/ligand coordination with Pd2+ from inexpensive commercially available starting materials and using standard laboratory techniques. The structure of this organic inorganic hybrid material was characterized by SEM, TEM, XRD, elemental analyzer, atomic absorption spectroscopy, N2 adsorption-desorption (BET), and FT-IR techniques. The catalytic performance of this novel heterogeneous catalyst was determined for the Suzuki cross-coupling and aerobic oxidation of benzyl alcohols. The composite exhibited an excellent catalytic activity and reuse ability of various recycles in air for the aforementioned organic transformations. TEM images of the recovered catalyst showed retained ordered mesostructure of SBA-15 with no damage in the periodic structure of the silicate framework and a good dispersion of in situ generated palladium nanoparticles within the SBA-15 structure.

Antileishmanial ferrocenylquinoline derivatives: Synthesis and biological evaluation against Leishmania donovani

The emergence of resistance against existing antileishmanial drugs necessitates the search for new classes of antileishmanial compounds. Herein a series of structurally diverse ferrocenylquinolines have been synthesized and evaluated for in?vitro antileishmanial activity against Leishmania donovani using?the MTT assay. Thirteen (M2-M14) substituted ferrocenylquinoline congeners possessing triazole?rings?were generated by palladium mediated Suzuki-Miyaura coupling reaction of 5-iodoferrocenylquinolinetriazole and substituted arylboronic acids. All the synthesized compounds were tested for its antileishmanial activity using both promastigote and amastigote stages of L.?donovani. Among them, three compounds (M4, M7 and M9) exhibited promising anti-promastigote activity, with an IC50value of 28.7?muM, 22.1?muM and 28?muM, respectively, and no cytotoxicity toward host splenocytes. These three compounds are equally effective against the intracellular amastigote stage of L.?donovani showing the IC50values of 16?muM (M4), 8?muM (M7) and 16?muM (M9), respectively, with consistent nitric oxide generation as required for parasite clearance. From the battery of tests conducted in this study, it appears that these compounds induce parasite death by promoting cell cycle arrest and triggering apoptosis.

Nanoscale polypyrrole sensors for near-field electrochemical measurements

Scanning electrochemical microscopy (SECM) is an electrochemical technique that is used to measure redox activity local to the surface of a sample. The incorporation of shear force (SF) feedback into SECM enables the concurrent acquisition of topographical data. Contemporary SECM measurements require a redox mediator (such as ferrocene methanol (FcMeOH)) for electrochemical measurements; however, redox mediators are detrimental to chemically sensitive materials such as biological cells. In this article, nanoscale polypyrrole membranes doped with dodecylbenzene sulfonate (PPy(DBS)) are deposited at the tip of highly sensitive ultra-microelectrodes (UME) to demonstrate a novel modification of the contemporary SECM?SF imaging technique that operates in the absence of a redox mediator. This technique leverages the redox activity of a PPy(DBS) membrane to locally detect changes in cation concentration. In conjunction with SF imaging, the PPy(DBS) membrane can (i) detect changes in distance from the surface by measuring changes in ion concentration of the diffusion shell, or (ii) detect local cation flux due to cell function when kept at a constant distance from the cell surface through SF-imaging techniques. Therefore, we predict this technique to enable high resolution mapping of surface cation concentrations and impact the field of biological imaging.

Binary Phosphorene Redox Behavior in Oxidoreductase Enzymatic Systems

Phosphorene is a two-dimensional material that has many advantageous electronic, electrochemical, and optical properties. However, phosphorene possesses a relatively poor stability in ambient atmosphere. This disadvantage limits its application in several systems and particularly in electrochemical biosensors. Here we evaluate phosphorene as an electrochemical biosensing platform in two different mediator-based oxidoreductase enzymatic systems (glucose oxidase (GOx) and peroxidase from horseradish (HRP)), in which their detection is based on the reduction or oxidation of a mediator. In both cases, the used mediator is the same, ferrocene methanol (FcMeOH). Enhanced electrochemical activity is observed only in the reductive system (HRP-based biosensor) when compared to the oxidative counterpart (GOx-based biosensor). This phenomenon is attributed to the fact that in a reductive environment the phosphorene structure remains intact, while in an oxidative potential, the phosphorene is readily oxidized. In this way, the electroactivity of phosphorene as a sensing platform is strongly dependent on the type of mediator-based enzymatic system. These findings of binary nature of phosphorene are of high importance for construction of phosphorene-sensing platforms and in the development of enzyme logic systems.

Investigation on the potential use of the mimetic peroxidase-catalyzed reaction of hydrogen peroxide and catechol in aqueous-organic mixtures

The reaction between hydrogen peroxide and catechol catalyzed by mimetic peroxidase hemin has been adapted to determination of trace amounts of H 2O2. The present work employs hemin as mimetic peroxidase to catalyze the oxidation of catechol by H2O2. Its intermediate is obtained in aqueous-organic two phases and the absorption peaks at 260 nm. The catalytic optimum conditions for hemin-H2O 2-catechol two phases system were studied. As low as 2 ¡Á 10-6 M H2O2 could be detected with a linear range from 3 ¡Á 10-6 M to 1 ¡Á 10-4 M via spectrophotometry.

Influence of methylimidazole isomers on ferrocene-catalysed nitrogen doped carbon nanotube synthesis

Nitrogen doped multi-walled carbon nanotubes (N-CNTs) were synthesized by the solid state pyrolysis of ferrocenylmethylimidazole or a mixture of ferrocene (FcH)/i-methylimidazole (i = 1, 2 and 4) at 800 C at different ratios in sealed quartz tubes. Transmission electron microscopy (TEM) images confirmed that the carbon nanotubes (CNTs) obtained were doped with nitrogen to give nitrogen doped multi-walled CNTs (N-CNTs). N-CNTs showed bamboo-like structures for the CNTs produced from both ferrocenylmethylimidazole and the mixtures of FcH/i-methylimidazole at varying ratios. The study revealed that the different imidazoles produced different types/size distributions of shaped carbon nanomaterials (SCNMs) including N-CNTs with different diameters. An investigation of the bamboo structures revealed that the three methylimidazole isomers led to tubes with different individual bamboo compartment distances and different morphologies including different N contents. This confirms that the synthesis of N-CNTs is determined by fragments (ratios, types) produced by decomposition of reactants at high temperature.
