a Scheme of the biosensor construction for Mb detection. A flat gold wire is used as electrode to be functionalized with anti-Mb, blocked with BSA, and finally tested with Mb; b shows the impedance values for each step of the biosensor construction; and c the impedance values shown through a Nyquist plot for increasing concentration of the analyte.
