22 p, 1.2 MB A novel bio-electronic tongue using cellobiose dehydrogenase from different origins to resolve mixtures of various sugars and interfering analytes / Cipri, Andrea (Universitat Autònoma de Barcelona. Departament de Química) ; Schulz, Christopher (Lunds universitet. Department of Analytical Chemistry/Biochemistry and Structural Biology) ; Ludwig, Roland (Universität für Bodenkultur Wien. Department of Food Science and Technology) ; Gorton, Loo (Lunds universitet. Department of Analytical Chemistry/Biochemistry and Structural Biology) ; Valle Zafra, Manuel del (Universitat Autònoma de Barcelona. Departament de Química)
A novel application of cellobiose dehydrogenase (CDH) as sensing element for a Bioelectronic Tongue (BioET) system has been tested. In this work CDHs from various fungi, which exhibit different substrate specificities, were used to discriminate between lactose and glucose in presence of the interfering matrix compound Ca²⁺ in various mixtures.

Second generation ethanol is produced from the carbohydrates released from the cell wall of bagasse and straw of sugarcane. The objective of this work is the characterization and application of a voltammetric electronic tongue using an array of glassy carbon electrodes modified with multi-walled carbon nanotubes containing metal (Paladium, Gold, Copper, Nickel and Cobalt) oxy-hydroxide nanoparticles (GCE/MWCNT/MetalsOOH) towards a simpler analysis of carbohydrates (glucose, xylose, galactose and mannose). [...]

186 p, 5.6 MB Carbon nanotubes and metal nanoparticles as electrode platform for sensors and biosensors / Cipri, Andrea ; Valle Zafra, Manuel del, dir. (Universitat Autònoma de Barcelona. Departament de Química) ; Universitat Autònoma de Barcelona. Departament de Química
Este trabajo se centra principalmente en la mejora de las propiedades de los sensores y/o biosensores utilizando nanotubos de carbono y nanopartículas metálicas como plataformas de electrodo. Después de haber considerado varios ejemplos de la literatura, para alcanzar este objetivo se ha decidido integrar las nanopartículas metálicas en la superficie de los nanotubos de carbono para conseguir las ventajas de las propiedades de los dos materiales; por esta razón se han ensayado diversos procedimientos de síntesis de la literatura, y éstos han sido adaptados y optimizados. [...]
This work is mainly focused on the improvement of the properties of sensors and/or biosensors using carbon nanotubes and metal nanoparticles as electrode platform. After having gone through a good amount of literature examples, to reach this goal it has been decided to embed the metal nanoparticles on the carbon nanotubes surface to be able to take advantage of both material properties; for this reason, various synthetic procedures from the literature has been tested, modifying and optimizing them. [...]
