Coordinated Dispersion and Aggregation of Gold Nanorod in Aptamer-Mediated Gestational Hypertension Analysis

Figure 3

Optimization of aptamer concentration. (a) Aptamer with concentrations of 1.25 to 20 μM was mixed independently with GNR and the aggregation was checked in the presence of NaCl. Inset displays the color developments. (b) Peak absorbance maximums with different concentrations of aptamer, averaged with different experimental replicates. The arrow indicates the direction of the changes.
