(a) Limit of detection with cortisol. Cortisol concentrations from 0 to 1 mg/mL were mixed independently with GNR-aptamer conjugates and the aggregation was checked in the presence of NaCl. Inset displays the color developments. (b) Peak absorbance maximums with different concentrations of cortisol, averaged with different experimental replicates. The arrow indicates the direction of the changes.
