The presence of Fe@C Nps layer at electrode surface and the presence of magnetic field guarantee the electroactivity of ceruloplasmin.
The ferromagnetic electrode modifier (Fe@C Nps) and external magnetic field allow the determination of Cp without any pre-concentration step.
Direct voltammetric sensor for detection of ceruloplasmin in blood has been developed.
The proposed Cp sensor is sensitive, reproducible and has very low limit of detection (pM level).
