Resumen:
Melanin-modified highly oriented pyrolytic graphite (HOPG) surfaces have been prepared by a simple
electrochemical method from synthetic eumelanin-containing aqueous solutions. The melanin film turns
the chemically inert HOPG surface into a highly active surface able to bind metallic cations. Ironmelaninmodified
HOPG surfaces catalyze the hydrogen peroxide electroreduction. These results are interesting
for applications in electrocatalysis, electroanalysis, and also as biomimetic systems for studying melanin
interactions with nanoparticles and metallic cation-containing drugs.
