Abstract
The potential of gold nanoparticles with appended metalloporphyrin synthesized through one-pot sono-synthesis and incorporated in conductive PANI and PPy polymeric coatings deposited on SPEs for catalytic oxidative detection of dopamine (DA) has been evaluated. The CV and LSV studies of developed composite materials have demonstrated their specific response to DA n in 2.5×10⁻⁵ – 1.0×10⁻³ M concentration range. The morphology of electropolymerized PPy and PANI polymeric coatings bearing ZnTPP(CO₃)4@AuNPs and ZnTPP(SO₃)4@AuNPs were tested my SEM and spectroscopic methods.
