Fig 1: Selectivity test of the rGO aptasensors using PBS (pH 7.4, 1×), 10-fold-diluted human serum in PBS (pH 7.4, 1×), cTnI (1 µg mL-1), Myoglobin (1 µg mL-1) and cTnT (10 pg mL-1) in the two media. The error bars indicate the standard deviations of the measurements. One-way analysis of variance (ANOVA) was used to check whether the measured RRCs were significantly different. (ns: p > 0.05 and ***p < 0.0001).
