One-step synthesis of Pt-decorated graphene–carbon nanotubes for the electrochemical sensing of dopamine, uric acid and ascorbic acid

Platinum nanoparticle-decorated graphene and carbon nanotube (Pt-Gr-CNT) nanocomposites synthesized by a single step chemical vapor deposition process, serve as a promising platform for the simultaneous electrochemical sensing of dopamine, uric acid and ascorbic acid.
