Determinação de açucares em bagaço de palha de cana-de-açúcar por cromatografia líquida de alta eficiência com detecção eletroquímica utilizando eletrodos de nanotubos modificados com óxidos metálicos
(Universidade Estadual Paulista (Unesp), 2015-11-26)
Biomass generated from the bagasse from sugarcane is a byproduct of the production process of sugar and ethanol. New applications for the bagasse have been developed among them we can highlight the production of biofuels ...
Electrooxidation of DNA at glassy carbon electrodes modified with multiwall carbon nanotubes dispersed in polyethylenimine
(2011)
This work reports the electrochemical response of the complex between dsDNA and PEI formed in solution and at the surface of glassy carbon electrodes (GCE) modified with a dispersion of multi-walled carbon nanotubes in ...
Enhanced electrochemical response of carbon quantum dot modified electrodes
(Elsevier Science, 2018-02)
A glassy carbon electrode (GCE) was surface-modified with carbon quantum dots (CQDs) and applied for the effective enhancement of the electrochemical signal for dopamine and uric acid determination. CQDs were prepared from ...
Dispersion of bamboo type multi-wall carbon nanotubes in calf-thymus double stranded DNA
(2013)
We report for the first time the use of double stranded calf-thymus DNA (dsDNA) to successfully disperse
bamboo-like multi-walled carbon nanotubes (bCNT). The dispersion and the modified electrodes were
studied by different ...
Electrochemical sensor for amino acids and glucose based on glassy carbon electrodes modified with multi-walled carbon nanotubes and copper microparticles dispersed in polyethylenimine
(Elsevier Science Sa, 2016-03-15)
This work reports the analytical performance of glassy carbon electrodes (GCE) modified with multi-walled carbon nanotubes (CNT) and copper microparticles dispersed in polyethylenimine (PEI) (GCE/CNT-PEI-Cu) for the ...
Electrochemical Oxidation Of Glassy Carbon Provides Similar Electrochemical Response As Graphene Oxide Prepared By Tour Or Hummers Routes
(WILEY-V C H VERLAG GMBHWEINHEIM, 2015)
Modified glassy carbon electrode with AuNPs using cis-[RuCl(dppb)(bipy)(4-vpy)]+ as crossed linking agent
(ElsevierAmsterdam, 2014-08)
This work links aspects of non-covalent interaction among gold nanoparticles (AuNPs) and ruthenium complexes, which were used to modify the surface of the glassy carbon electrode (GCE), without the necessity of a sulfur ...
1,3-dioxolane: A green solvent for the preparation of carbon nanotube-modified electrodes
(Elsevier Inc., 2014)
One of the main challenges associated with the handling of carbon nanotubes (CNTs) for modifying electrodes is the production of adequate dispersions. We report the first example in which 1,3-dioxolane was used to produce ...
Multivariate analysis for resolving interactions of carbidopa with dsDNA at a fullerene-C60/GCE
(Elsevier Science, 2014-06)
For the first time, interactions of carbidopa (CD) with double-stranded calf thymus DNA (dsDNA) in a phosphate buffered solution (PBS, 0.05 M, pH = 4.0) at a fullerene-C60/glassy carbon electrode (FLR/GCE) has been studied ...
Electrochemistry and XPS of 2,7-dinitro-9-fluorenone immobilized on multi-walled carbon nanotubes
(Springer, 2016)
We report that glassy carbon electrodes (GCE) modified with multi-walled carbon nanotubes (MWCNTs) can be derivatized with 2,7-dinitro-9-fluorenone (2,7-NFN). The derivatization procedure involves simple immersion of the ...
