Modification of composites of block copolymers-gold nanoparticles with enzymes and their characterization by electrochemical techniques
(SPRINGER, 2011)
In this work, the poly(styrene-vynil pyridine) block copolymer was used as a porous pattern to study the electrodeposition of gold inside the pores, as a new method to obtain gold nanoparticles. The porous pattern left by ...
New Hybrid Nanocomposites with Catalytic properties obtained by In situ preparation of gold nanoparticles on poly (ionic liquid)/poly (4-vinylpyridine) nanofibers
(MDPI, 2022)
In this work, we report the obtaining of new hybrid nanocomposites with catalytic activity formed by nanofibers of polymer blends and gold nanoparticles. The nanofibers were obtained by electrospinning blends of a poly ...
Building hot spots in different plasmonic nanoparticles from a cruciform bifunctional dipyridine anthracene
(John Wiley and Sons Ltd, 2019)
In this work, the adsorption of a type of cruciform system integrated by an anthracene central part and two side chains with a pyridine-vinyl structure (DPAC) was studied on plasmonic nanoparticles of silver and gold. The ...
Oxygen cathode based on a layer-by-layer self-assembled laccase and osmium redox mediator
(Elsevier, 2008-09-09)
Trametes trogii laccase has been studied as biocatalyst for the oxygen electro-reduction in three different systems: (i) soluble laccase was studied in solution; (ii) an enzyme monolayer was tethered to a gold surface by ...
Estudio de sistemas bifuncionales para la obtención de 5-(Hidroximetil)-2-Furaldehído y Acido 5-(Hidroximetil)Furan-2-Carboxílico
(Universidad Pedagógica y Tecnológica de ColombiaFacultad de Ciencias. Escuela de Posgrados. Maestría en Química, 2017)
In this work the dehydration of fructose and glucose to 5-(hydroxymethyl)-2-furaldehyde (HMF) was studied on a bifunctional system based on LaOCl/Nb2O5 catalysts and hot compressed water. The catalysts were prepared by ...
Síntesis de cumarinas 3-azometino-sustituidas como quimiosensores para la detección de iones Pb2+ y Hg2+ en medio acuoso.
(Universidad Nacional de ColombiaMedellín - Ciencias - Maestría en Ciencias - QuímicaEscuela de químicaFacultad de CienciasMedellínUniversidad Nacional de Colombia - Sede Medellín, 2021-08-27)
Metales como el plomo y mercurio no se le conoce función fisiológica beneficiosa en el cuerpo humano, su acumulación hace que resulte tóxico, debido a la afinidad que presenta al grupo sulfhidrilo (-SH) provocando la ...
