Graphene Quantum Dot-Doped PEDOT for Simultaneous Determination of Ascorbic Acid, Dopamine, and Uric Acid

Invited for this issue's Front Cover is the group of Prof. Dr. Tae Hyun Kim from Soonchunhyang University (South Korea). The cover picture illustrates poly(3,4-ethylenedioxythiophene) (PEDOT) electrodeposited thin films (PEDOT-GQD) doped with graphene quantum dots (GQD) as an electrode active material that has a high electrochemically active area and interfacial electron transport rate. As a result, PEDOT-GQD will simultaneously detect ascorbic acid, dopamine, and uric acid with high selectivity and high sensitivity.
