The demand for new devices that enable the detection of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) at a relatively low cost and that are fast and feasible to be used as point-of-care is required overtime on a large scale. In this sense,
Chronoamperometry (ChA) and square-wave voltammetry (SWV) analyses were performed in the presence of 0.01 mM of K3 [Fe(CN)6]/K4 [Fe(CN)6] (1:1) mixture and 0.1 M KCl. For the ChA measurements, tequilibrium time = 2, interval time = 0.1 s, run time = 200 s, and EDC =0 ...
