Glassy carbon electrodes modified with CNT dispersed in chitosan: Analytical applications for sensing DNA-methylene blue interaction
(Elsevier Science Sa, 2009-09)
In this work we report the optimization of a chitosan (CHI) and carbon nanotubes (CNT) modified electrode, CNT-CHI, to study the dsDNA interaction with methylene blue (MB), a well-known DNA intercalator. The analytical ...
Adsorption and Electrooxidation of DNA at Glassy Carbon Electrodes Modified with Multiwall Carbon Nanotubes Dispersed in Glucose Oxidase
(Wiley VCH Verlag, 2013-03)
We are proposing for the first time the successful immobilization of DNA at glassy carbon electrodes (GCE) modified with carbon nanotubes (CNT) dispersed in glucose oxidase (GOx) (GCE/CNT-GOx) either by direct adsorption ...
Highly microporous sorbents from lignocellulosic biomass: Different activation routes and their application to dyes adsorption
Highly microporous carbons were produced from two abundant agricultural residues, olive tree pruning and coffee husk. Different activation routes were tested to obtain the adsorbents, choosing experimental conditions that ...
Micro mesoporous activated carbon from coffee husk as biomass waste for environmental applications
Activated carbons (ACs) with a highly developed porosity have been prepared from a lignocellulosic precursor (coffee husk) for environmental pollutant adsorption. Characterization results show that these materials exhibit ...
Iron oxide dispersed over activated carbon: Support influence on the oxidation of the model molecule methylene blue
(Elsevier Science, 2009-10-01)
In this work materials based on iron oxide dispersed over activated carbon were prepared and tested in the H2O2 decomposition and removal of the methylene blue (MB) model from aqueous solution. Two different supports were ...
