PORRAS GUTIERREZ, ANA et al. CATALYTIC ACTIVITY OF ELECTRODE MATERIALS BASED ON POLYPYRROLE, MULTI-WALL CARBON NANOTUBES AND COBALT PHTHALOCYANINE FOR THE ELECTROOXIDATION OF GLUTATHIONE AND L-CYSTEINE. J. Chil. Chem. Soc. [online]. 2012, vol.57, n.3, pp.1244-1247. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072012000300010.

Electrodes prepared from overoxidized pyrrole, multi-walled carbon nanotubes (MWCNT) and cobalt phthalocyanine (CoPc) exhibit a clear catalytic activity for the electrooxidation of L-cysteine and reduced gluthatione. The electrodes are more stable than the ones modified by simple adsorption of CoPc and/or MW-CNT. Therefore, these materials offer a good alternative for the development of electrocatalytic applications and thiols detection in biological interest.

Palavras-chave : Electrocatalysis; thiols; modified electrodes; carbon nanotubes.
