A highly sensitive dopamine sensor based on a polyaniline/reduced graphene oxide/Nafion nanocomposite

A highly conductive nanocomposite of polyaniline/reduced graphene oxide (PANI-rGO) was prepared using one-pot solvethermal method, and then a hybrid material of PANI-rGO and Nafion (PANI-rGO-NF) was obtained upon ultrasonication, and used to modify glassy carbon electrode for the trace determination of dopamine (DA).99
