Anthraquinone Functionalized Ionic Liquid Based Disposable Electrochemical Sensor for the Enzyme-Free Detection of Hydrogen Peroxide
A simple and selective enzyme-free electrochemical sensor for H 2 O 2 has been designed and fabricated using ionic liquid (IL) tagged anthraquinone (AQ) modified electrode (AQ-PF 6 -IL). This newly synthesized AQ-PF 6 -IL has been systematically characterized, after which it has been immobilized ove...

6
-IL has been systematically characterized, after which it has been immobilized over a screen-printed electrode to produce AQ-PF
6
-IL/SPE. The electrochemical investigation of AQ-PF
6
-IL/SPE displayed a set of distinct redox peaks attributable to the anthraquinone/anthrahydroquinone redox pair. Interestingly, AQ-PF
6
-IL/SPE has shown enhanced peak current at reduced formal potential for AQ, when compared to AQ/SPE. Further, the electrocatalytic activity of AQ-PF
