This work aims to develop a novel electrode based on graphene loaded nanofibers for sensitive electrochemical detection of biomolecules (i.e. dopamine) and heavy metals. The very low limit of detection are obtained for both dopamine and heavy metals. Thus, this system is applied for the sensitive detection of these compounds in real samples.
