Bi-Directional Electrocatalytic Detection of Dopamine at an Electrode Modified with Ferrocene-Filled Carbon Nanotube Peapods

A glassy carbon electrode (GCE) was modified with nanopeapods formed by ferrocene filled single‐walled carbon nanotubes (Fc@SWNTs). The modified electrode showed bi‐directional electrocatalysis toward dopamine (DA), which suggested a synergistic effect of ferrocene and carbon nanotubes. Bi‐directional detection of DA was realized based on the modified...
