Structural and Luminescence Properties of Silica-Based Hybrids Containing New Silylated-Diketonato Europium(III) Complex

Organosilylated complex [Eu(TTA)3(Bpy-Si)]: A bifunctional moiety for the engeneering of luminescent silica-based nanoparticles for bioimaging

A new highly luminescent europium complex with the formula [Eu(TTA) 3(Bpy-Si)], where TTA stands for the thenoyltrifluoroacetone, (C 4H3S)COCH2COCF3, chelating ligand and Bpy-Si, Bpy-CH2NH(CH2)3Si(OEt)3, is an organosilyldipyridine ligand displaying a triethoxysilyl group as a grafting function has been synthesized and fully characterized. This bifunctional complex has been grafted onto the surface of dense silica nanoparticles (NPs) and on mesoporous silica microparticles as well. The covalent bonding of [Eu(TTA)3(Bpy-Si)] inside uniform Stöber silica nanoparticles was also achieved. The general methodology proposed could be applied to any silica matrix, allowed high grafting ratios that overcome chelate release and the tendency to agglomerate. Luminescent silica-based nanoparticles SiO2-[Eu(TTA)3(Bpy-Si)], with a diameter of 28 ± 2 nm, were successfully tested as a luminescent labels for the imaging of Pseudomonas aeruginosa biofilms. They were also functionalized by a specific monoclonal antibody and subsequently employed for the selective imaging of Escherichia coli bacteria. © 2013 American Chemical Society.

Bifunctional silica nanoparticles for the exploration of biofilms of Pseudomonas aeruginosa

Luminescent silica nanoparticles are frequently employed for biotechnology applications mainly because of their easy functionalization, photo-stability, and biocompatibility. Bifunctional silica nanoparticles (BSNPs) are described here as new efficient tools for investigating complex biological systems such as biofilms. Photoluminescence is brought about by the incorporation of a silylated ruthenium(II) complex. The surface properties of the silica particles were designed by reaction with amino-organosilanes, quaternary ammonium-organosilanes, carboxylate-organosilanes and hexamethyldisilazane. BSNPs were characterized extensively by DRIFT, 13C and 29Si solid state NMR, XPS, and photoluminescence. Zeta potential and contact angle measurements exhibited various surface properties (hydrophilic/hydrophobic balance and electric charge) according to the functional groups. Confocal laser scanning microscopy (CLSM) measurements showed that the spatial distribution of these nanoparticles inside a biofilm of Pseudomonas aeruginosa PAO1 depends more on their hydrophilic/hydrophobic characteristics than on their size. CLSM observations using two nanosized particles (25 and 68 nm) suggest that narrow diffusion paths exist through the extracellular polymeric substances matrix. © 2013 Copyright Taylor and Francis Group, LLC.

O Ensino de arquitetura da informação: uma proposta para os cursos de Biblioteconomia da Universidade Federal do Ceará

In the Learning Society, understand the nature of digital information is relevant for librarians, which broadened its performance, it must create, organize, add metadata, and evaluate usability and accessibility to disseminate digital information in environments web. This paper discusses the creation and implementation of the Information Architecture discipline as discipline in courses of Science Librarian of Universidade Federal do Ceará. It is an analysis evidenced from observations in the classroom. The methodology of this study is anchored in the qualitative approach and has a descriptive character. As a result, we present the construction process of the aims of discipline, the menu and the curriculum.

Cultura, história e saúde: análise de enquadramento do jornalismo especializado em gastronomia

This experimental project focused on a specialization in journalism that is becoming increa-singly present in the media: the gastronomic journalism. The aim was to understand the speci-ficities of segmentation in the news and editorial spreads profile area for deepening the dining experience in contemporary society, considering the contribution of information to maintain proper eating habits and cultural enrichment of the reader. The research involved a literature review and survey of the history of gastronomy and cultural aspects, analysis and reporting framework for the months of August and September 2010 the Food section of the newspaper Folha de S. Paul, Taste of the book, the newspaper O Estado de S. Paul and the Menu maga-zine segment, Publisher of Three in order to identify the presence of aspects related to culture, history, health and nutrition
