摘要：
A glassy carbon electrode (GCE) modified with ferrocenecarboxamide, gold nanoparticles and multiwall carbon nanotubes was constructed and characterized by field emission scanning electron microscopy and cyclic voltammetry. The electrochemical behavior of bilirubin (BR) on the modified electrode was investigated and it was found that the modified electrode had an obvious electrocatalytic effect on bilirubin. Compared with a bare GCE, the modified electrode exhibited a marked enhancement in the current response for bilirubin. Amperometry was employed to investigate the electrocatalytical oxidation of bilirubin on the modified electrode. As a result, it exhibits an excellent electrocatalytic response to bilirubin with a response time of less than 5 s, a broad linear range of 1 to 100 μmol L−1, as well as good long-term stability and reproducibility.
