Voltammetric sensor for simultaneous determination of p-phenylenediamine and resorcinol in permanent hair dyeing and tap water by composite carbon nanotubes/chitosan modified electrode
(Elsevier B.V., 2014-09-01)
p-Phenylenediamine (PPD) and resorcinol (RSN) are hair dye precursors of permanent dyeing more used worldwide. The present work describes a simple and economic voltammetric sensor for simultaneous determination of both ...
Electrochemical sensors for dopamine using graphene-cobalt(II) complex modified glassy carbon electrode by adsorptive voltammetry
(Analytical and Bioanalytical Electrochemistry, 2019)
Underivatized amino acids detection by anion-exchange chromatography coupled to a nanostructured detector
(2021-06-01)
This work reports the development of a fast and reliable amperometric sensor for the detection of amino acids. The detector was constructed using copper nanoparticles (CuNPs) supported on reduced graphene oxide (RGO) ...
Non-covalent functionalization of multi-walled carbon nanotubes with cytochrome c: Enhanced direct electron transfer and analytical applications
(Elsevier Science Sa, 2016-03-31)
This work reports the non-covalent functionalization (dispersion) of multi-walled carbon nanotubes (MWCNTs) with cytochrome c (Cyt c), the direct electron transfer (DET) after drop-coating deposition of MWCNTs-Cyt c ...
A simple derivatization of multiwalled carbon nanotubes with nitroaromatics in aqueous media: Modification with nitroso/hydroxylamine groups
(ELSEVIER SCIENCE INC, 2011-02)
We report that GCE modified with MWCNTs can be derivatized by the nitroaromatic drug nitrendipine (NTD) ((RS)-ethyl methyl 2,6-dimethyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate) simply by dipping the electrode ...
Carbon nanotubes–ionic liquid gel. Characterization and application to pseudoephedrine and chlorpheniramine determination in pharmaceuticals
(Sociedad Chilena de Quimica, 2019)
A multi-walled carbon nanotube (MWCNT)-ionic liquid (IL) film-modified glassy carbon electrode (GCE) was constructed for the determination of pseudoephedrine (PE) and chlorpheniramine (CP) by differential pulse voltammetry ...
