Resumen:
This review present a critical comparison of the electrochemical behavior and analytical performance of
glassy carbon electrodes (GCE) modified with carbon nanotubes (CNTs) dispersed in different polymers:
polyethylenimine (PEI), PEI functionalized with dopamine (PEI-Do), polyhistidine (Polyhis), polylysine
(Polylys), glucose oxidase (GOx) and double stranded calf-thymus DNA (dsDNA). The comparison is
focused on the analysis of the influence of the sonication time, solvent, polymer/CNT ratio, and nature
of the polymer on the efficiency of the dispersions and on the electrochemical behavior of the resulting
modified electrodes. The results allow to conclude that an adequate selection of the polymers makes pos-
sible not only an efficient dispersion of CNTs but also, and even more important, the building of successful
analytical platforms for the detection of different bioanalytes like NADH, glucose, DNA and dopamine.
