Simultaneous determination of ascorbic acid, dopamine, and uric acid using graphene quantum dots/ionic liquid modified screen-printed carbon electrode

Novel GQDs/IL-SPCE for AA, DA, and UA simultaneous determination was developed.The synergistic effect of GQDs and IL exhibited remarkable electrocatalytic activity.LODs of the simultaneously detection of AA, DA, and UA were found to be very low.The developed method was successfully applied for real samples with high accuracy.
