Abstract
Boron doped diamond (BDD) electrodes were functionalized with receptors specific to COVID-19 viralproteins. It was shown that the concentration of the protein can be quantitatively estimated using elec-trochemical impedance spectroscopy (EIS). Detection was successful using the standard methodologywith external redox marker, as well as without the marker. Pros and cons of both strategies are dis-cussed, emphasizing the differences in measurements protocols, electrode stability, and reliability ofthe results.
