Figure 6. Analysis of cardiac troponin I based on stripping voltammetry of AuNPs with detection limit of 10-10 g/ml (4.25 10^-12 М). Dependence of the cathodic peak current of Auel stripping voltammetry on the amount of cTnI in plasma samples. I₀ corresponds to average cathodic peak current of plasma of healthy donors (HD). Inset: stripping voltammograms of SPE/AuNPel/DDAB/anticTnI+plasma of HD (A), SPE/AuNPel/DDAB/anti-cTnI+plasma of AMI (B, Acute myocardial infarction) [14].
