摘要
Electrochemical oxidation of conjugated bilirubin has been studied on an indigenously screen-printed carbon electrode (SPCE). Microscopic, spectroscopic and electrochemical methods thoroughly characterized the electrode. The surface morphology of SPCE revealed graphite nanoparticles of size around 100 nm. The oxidation of bilirubin occurred on SPCE at lower anodic potential and was highly selective towards conjugated bilirubin in the presence of interfering molecules. The SPCE showed a dynamic detection range of 1–600 µM. Conjugated bilirubin spiked urine samples were tested on SPCE and found excellent response.
