a (I)-Electrochemical characterization of metal/metal-oxides/CNTs modified electrodes using cyclic voltammetry (CV) at the scan rate of (50 mV/s), and potential range (−0.2 to 1.0 V). (II)-Electrochemical impedimetric spectroscopy (EIS) was conducted within the frequency (10,000 to 0.1 Hz) and the applied DC of +0.4 V. FCN (5 mM) was used as the standard redox probe. b Voltammetric and impedimetric characterizations (I and II, respectively) of the immune-sensor surface changes including the surface functionalization with the cross-linking agents (4-ATP), and a mixture of SARS-CoV-2 antibodies
