Avidin and glucose oxidase-non-covalently functionalized multi-walled carbon nanotubes: A new analytical tool for building a bienzymatic glucose biosensor
(Wiley VCH Verlag, 2019-05)
We report an innovative supramolecular architecture for bienzymatic glucose biosensing based on the non-covalently functionalization of multi-walled carbon nanotubes (MWCNTs) with two proteins, glucose oxidase (GOx) (to ...
Carbon nanotubes non-covalently functionalized with cytochrome c: A new bioanalytical platform for building bienzymatic biosensors
(Elsevier, 2016)
We report for the first time the use of glassy carbon electrodes (GCE) modified by drop-coating with multi-walled carbon nanotubes (MWCNTs) dispersed in cytochrome c as platform for the construction of bienzymatic biosensors, ...
Description of chemically and thermally treated multi-walled carbon nanotubes using sequential decomposition of adsorption isotherms
(World Scientific, 2016-08)
The effect of wet acid oxidation by means of sulfuric/nitric acid mixtures, and high-temperature treatment of commercial arc-discharge synthesized multi-walled carbon nanotubes (MWCNTs) was studied. In order to analyze the ...
Unveiling the Influence of Carbon Nanotube Diameter and Surface Modification on the Anchorage of L-Asparaginase
(Mdpi, 2022-09-01)
L-asparaginase (ASNase, EC 3.5.1.1) is an amidohydrolase enzyme known for its anti-cancer properties, with an ever-increasing commercial value. Immobilization has been studied to improve the enzyme's efficiency, enabling ...
Doble role of bathocuproine disulfonic acid as multi-walled carbon nanotubes dispersing agent and copper preconcentration ligand: Analytical applications for the development of hydrogen peroxide and glucose electrochemical sensors
(Elsevier Science, 2020-11)
We are reporting a new strategy for preparing carbon nanotubes (CNTs)-based hydrogen peroxide and glucose amperometric sensors by taking advantage of the dual role of bathocuproine disulfonic acid (BCS) as dispersing agent ...
Modulation of the electrocatalytic activity of Fe phthalocyanine to carbon nanotubes: electrochemistry of l-cysteine and l-cystine
(2019)
We have evaluated the electrocatalytic activity of hybrid electrodes containing Fe(II) phthalocyanine and tested these electrodes for l-cysteine oxidation and l-cystine reduction. The hybrid electrodes consisted of pristine ...
Multi-walled carbon nanotubes functionalized with bathocuproinedisulfonic acid: Analytical applications for the quantification of Cu(II)
(Springer Heidelberg, 2020-08)
This work reports the successful non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) with bathocuproinedisulfonic acid (BCS) and the analytical application of the resulting dispersion (MWCNTs-BCS) to ...
A novel architecture based upon multi-walled carbon nanotubes and ionic liquid to improve the electroanalytical detection of ciprofibrate
(Royal Society of Chemistry - RSCCambridge, 2014-08)
Voltammetric studies have been carried out using a glassy carbon electrode (GCE) modified with multi-walled carbon nanotubes (MWCNTs) and the ionic liquid 1-butyl-3-methylimidazolium chloride (IL). Studies on the electrochemical ...
