Resumen:
Thiol-capped gold nanoparticles modified with iron-melanin are attractive because they combine magnetic properties and biocompatibility. The biopolymer modified  nanoparticles are prepared and delivered  following a three step strategy: i) adsorption of thiol-capped metal nanoparticles on graphite, ii)  electrochemical deposition of melanin-iron, iii) potential-induced delivery of the modified nanoparticles to the electrolyte. The gold nanoparticles prepared by this method are characterized by XPS, HRTEM, SAXS and electrochemistry.
