Amperometric detection of dopamine based on tyrosinase–SWNTs–Ppy composite electrode

A novel 3-dimensional single wall carbon nanotubes (SWNTs)–polypyrrole (Ppy) composite was prepared as an electrode by chemically polymerizing polypyrrole onto SWNTs using a LiClO 4 oxidant. This composite electrode was characterized by scanning electron microscopy (SEM) and cyclic voltammetry with...
