  Application of Raman-SERS spectroscopy in analysis characterization and identification of fungi and bacteria, Descrição: Early detection and identification of bacteria and filamentous fungi is very important to avoid devastating consequences for human life upon exposure to them. The characterization, detection and identification of bacteria and filamentous fungi using surface-enhanced Raman spectroscopy (SERS) is an emerging technique due to its ability to provide rich intrinsic molecular information about molecules and molecular structures in close proximity to noble metal surfaces. However, sample preparation methods and experimental conditions must be carefully evaluated in order to obtain clearly, reproducible and interpretable results. In this study a sample preparation for bacteria and fungi for SERS analysis was developed Four filamentous fungi strains, A Flavus, F. Verticilliodes, A. Alternata, A. Parasiticus and two bacteria strains Salmonella and Sthaphylococcus were evaluated to demonstrate the source of the spectral features of bacterial and filamentous fungi SERS spectra. It was found that the characteristics determined in fungal SERS spectra came up from the filamentous, spores, and hyphae molecular species detached from the biochemical structures on the cell surface. Also the SERS spectra of bacteria came from the bacteria cell wall and other molecular species detached from the biochemical structures on the cell surface, the same SERS spectra should be reproducible under the same experimental conditions.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Especialização: (1) . , Integrantes: Javier Christian Ramirez Perez - Coordenador / Marcia Rizzutto - Integrante., Financiador(es): Universidade de São Paulo - Outra., Número de produções C, T & A: 1

  Identification of anthocyanin-based natural dyes used as photosensitizers by means of Raman SERS at different pH, Descrição: Anthocyanin are an important class of natural compounds, present in Mortino and Hibiscus that we employed as vegetal photosynthetizers for fabrication of dyes synthetize solar cells. Anthocyanins belong to the family of flavonoids, but the color provided are not in the range of yellow shades. Red purple and blue were the hues that barriers their photosynthetic properties. In fact the color depend on the pH. Anthocyanins are present as glycosylated molecules were their respective aglycones are named anthocyanidins. The first part of the present work of the present research is devoted to characterization of anthocyanidins by means of Raman SERS at different pH values, exploiting the chemical specificity of the technique and its sensitivity to subtle changes in molecular structures, phenomena that occur extensively in chemistry of anthocynins. The second part of the research is going to in the identification anthocyanin-based dyes molecules on of Mortino and Hibiscus by means of Raman SERS and the enrichement of the Raman SERS data base of naturl dye products available in the literature.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Especialização: (1) / Mestrado acadêmico: (1) . , Integrantes: Javier Christian Ramirez Perez - Coordenador., Financiador(es): Universidade de São Paulo - Outra., Número de produções C, T & A: 1

  Silver nanoparticles size impact on Raman-SERS for characterization and identification of bacteria and fungi, Descrição: Filamentous fungi and bacteria play an important role in biotechnology and also as biodeterioration agents. The characterization, detection and identification of fungi and bacteria using Surface-enhanced Raman spectroscopy (SERS) can give chemical information on materials that are in close contact with metals substrates, such as silver nanoparticles (AgNPs). The power of this technique is attributed to its ability to provide rich intrinsic molecular information and molecular structures in close proximity to noble metal surfaces. The introduction of AgNPs enhance surface of microorganisms and suppress native biofluorescence. In addition, they are complementary non-invasive, high sensitivity vibrational information content for rapid analysis of microorganisms. Nevertheless, care must be exercised in sample preparation protocols and experimental conditions in order to obtain interpretable and reproducible results. In the present investigation, a sample preparation protocol of pure culture of fungi and bacteria was developed and the impact of AgNPs size on Raman-SERS spectroscopy was studied for identification and characterization of several fungi and bacteria. Three different sizes (5, 15 and 30 nm) of spherical AgNPs substrate were synthetized to obtain the maximal SERS enhancement. The AgNPs size distribution was assessed by Small-angle X-ray scattering (SAXS). Several fungi strains A Flavus, F. Verticilliodes, A. Alternata, A. Parasiticus, B. Bassiana and bacteria species: E.coli, Staphylococcus A., Bacillus, Salmonella were cultured in both agar and broth media, extracted with DI water and ethyl acetate and the extract mixed AgNPs of different size and spotted on a CaF2 slide, dried at room temperature until a thin biofilm was formed, and SERS spectra were measured. Preliminary results showed that sample preparation protocol is more convenient cultured fungi and bacteria in broth to prevent interferences from the culture media that may affect with the SERS substrate. The surface plasmon resonance increase as the AgNPs size increase from 5 to 30 nm enhancing the scattering intensity by several orders of magnitude. The characteristics of fungi and bacteria SERS spectra derive from the fungi and bacteria surface with some contribution of metabolites excretes from the microorganism and during the extraction with ethyl acetate. We recommend following the sample preparation protocol, not using ethyl acetate but using AgNPs of 30 nm as substrate. This research is in progress at different scales, reproducibility of the protocol and SERS effect, improve AgNPs, synthesis using in vivo fungi and bacteria for improving of bacteria and fungi.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Especialização: (2) / Mestrado acadêmico: (2) . , Integrantes: Javier Christian Ramirez Perez - Coordenador / Marcia Rizutto - Integrante., Financiador(es): Universidade de São Paulo - Cooperação., Número de produções C, T & A: 1 / Número de orientações: 1

  Uso de materiales hibridos para el desarrollo de celdas solares organicas y celdas de combustible, Descrição: La sociedad actualmente vive el desafío de desarrollar acciones que garanticen simultáneamente la mantención de los ecosistemas alrededor del mundo y de ofrecer energía e insumos a la población. La acumulación de CO2 en la atmosfera y el cambio climático asociado a este fenómeno es un indicio de la necesidad de resolver ese desafío en un plazo relativamente corto. Uno de los objetivos para incentivar el desarrollo sostenible consiste en diversificar la matriz energética tanto en Chile como a nivel mundial y aumentar las fuentes de energía renovables, como energía solar, hidráulica, eólica y biomasa. Dentro de las energías renovables, la energía solar se destaca por su enorme disponibilidad, 3x1024 J/ao lo que supera el consumo mundial 4.1x1020 J 1. Las celdas solares inorgánicas en base a silicio (Si) actualmente resultan muy caras, generan residuos contaminantes y han alcanzado un límite de eficiencia de conversión energética (>20%) 2, como una alternativa se están investigando a nivel global otro tipo de celdas solares fotovoltaicas, como las celdas solares sensibilizadas por colorantes (DSSCs), las celdas solares orgánicas (OSCs) y las celdas solares hibridas (HSCs). La diferencia entre las DSSCs y las OSCs está en el uso de semiconductores organicos, mientras que las OSCs son celdas de película solida de estructura amorfa, las DSSCs son de estructura semi-liquida e hibrida (orgánica e inorgánica), además las celdas solares hibridas (HSCs), una combinación de las dos anteriores. Estas celdas solares ofrecen la posibilidad de aprovechar adecuadamente la energía solar para la generar electricidad con bases competitivas con el costo actual de energía convencional. Propósito ? Disear y desarrollar celdas solares orgánicas, diodos emisores de luz orgánicos y membranas intercambiadoras de protones para celdas de combustible con materiales híbridos nanoestructurados a partir de pigmentos y biopolímeros naturales. ? Caracterizar los materiales hibridos nanoestructurados (1D, 2D) fotoanodos, fotocátodos, membranas biopolimericas, mediante análisis fisicoquímicos mediante RDX, AFM, SEM, FTIR, MRN, para determinar su morfología, área superficial, superficie interna, volumen de poro, espesor de la deposición y la película sobre el fotoanodo y fotocátodo. ? Evaluar la eficiencia de conversión energética de las celdas solares organicas (DSSCs; OSCs; HSCs), diodos emisores de luz (OLEDs), asi como en las celdas de combustible. ? Contribuir a la generación de fuentes de energía limpia con la participación de un equipo de investigación multidisciplinario de la UTFS en colaboración con otras instituciones de investigación nacionales e internacionales.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Especialização: (2) / Mestrado acadêmico: (2) . , Integrantes: Javier Christian Ramirez Perez - Coordenador., Número de produções C, T & A: 1 / Número de orientações: 1
