Cyclic voltammograms (A) and differential pulse voltammograms (B) after interaction with anti-rSpike antibodies of different concentrations (0–3.5 nM). Potential range was from −0.4 to +0.6 V, with a CV scan rate of 0.05 V/s, DPV step size of 0.004 V, pulse height of 0.05 V, pulse period of 100 ms, and pulse width of 50 ms, in 10 mM PBS, pH 7.4, containing 2 mM [Fe(CN6)]3−/4−. Signal normalised to the geometrical area of the working electrode (0.126 cm2). Data are represented as means of three independent experiments.
