چکیده
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 area and interfacial electron transport rate. As result, PEDOT-GQD will simultaneously detect ascorbic acid, dopamine, uric acid selectivity sensitivity. Read full text Research Article at 10.1002/celc.202200557.

Simultaneous determination of ascorbic acid, dopamine and uric acid using PEDOT polymer modified electrodes
Dopamine, uric acid and ascorbic acid have been determined simultaneously on a poly(3,4-ethylenedioxythiophene) modified electrode using electrochemical techniques. On a bare glassy carbon electrode, all three undergo oxidation and appear as a single peak at around 200 mV, whereas on the modified electrode, distinct peaks with clear potential separation are observed, paving way for their simult...
