摘要：

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 MWCNT. Therefore, these materials offer a good alternative for the development of electrocatalytic applications and thiols detection in biological interest.
