Graphene Quantum Dots in Electrochemical Sensors/Biosensors

摘要

Background: Graphene and its derivatives, as most promising carbonic nanomaterials havebeen widely used in design and making electrochemical sensors and biosensors. Graphene quantum dotsare one of the members of this family which have been mostly known as fluorescent nanomaterials andfound extensive applications due to their remarkable optical properties. Quantum confinement and edgeeffects in their structures also cause extraordinary electrochemical properties.Objective: Recently, graphene quantum dots besides graphene oxides and reduced graphene oxides havebeen applied for modification of the electrodes too and exposed notable effects in electrochemical responses.Here, we are going to consider these significant effects through reviewing some of the recentpublished works.
