A hybrid graphene-polypyrrole (PPy) composite-based platform was elaborated by using nanosphere lithography structuration. This platform was further used for the antibody anti-acetaminophen immobilization in order to obtain an immunosensor for selective detection of paracetamol (acetaminophen) by using electrochemical methods. After patterning of the composite layer, the five-fold improvement of electrochemical...
Two different graphene/β-cyclodextrin (CD)-based biosensors were elaborated for dopamine (DA) determination starting from glassy carbon electrode (GCE). First one was obtained by modifying GCE with reduced graphene oxide (RGO), CD and tyrosinase (Tyr) immobilized with a polyethylenimine film. The second biosensor was obtained after the incorporation of RGO functionalized with a new synthesized pyrrole-β-CD...
