In this study, we developed and characterized a new dopamine (DA) sensor based on the reduced graphene oxide (rGO)-carbon dot composite film with high sensitivity, nice specificity and good stability. The carbon dots (CDs) had carboxyl groups with negative charge, which not only provided good stabil...
