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
