Screen printing technology was utilized to print a thin layer (similar to 1 mu m) of hydrophobic room temperature ionic liquid (RTIL), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF(6)]), onto a disposable screen-printed carbon electrode (SPCE) to prepare a relatively easy to mass produce RTIL-modified electrode. In contrast to other RTIL composite electrodes using RTIL as the binder, our method can highlight the extraction ability of RTIL to improve the detection performance in the monitoring of biomolecules. In this study, we demonstrate that the screen-printed [BMIM][PF(6)]/preanodized SPCE (designated as SPIL-SPCE*) possesses high sensitivity and good selectivity for the detection of dopamine in the presence of high concentration of ascorbic acid.
