Electrochemical detection of the L-cysteine using a carbon paste electrode modified with a conjugate of tetraamino cobalt (II) pthalocyanine and gold nanoparticles

Gold nanoparticles protected with a mixture of hexanothiol and MUA (11-mercaptoundecanoic acid) (AuNP1) were reacted with Co(II) tetraaminophtalocyanine (CoTAPc). The resulting nanoparticles formed via covalent bonds, AuNP2, were characterized by absorption spectra, infrared spectroscopy and transmi...
