a Ln-aptamer does not significantly bind to meglumine and Gd-DOTA, as evidenced by the absence of fluorescence in the presence of these analytes. Data is plotted as average fluorescence reading (a.u.) ± standard deviation, n = 6. b Fold change of fluorescence (for Ln-aptamer) and 573/433 nm absorbance ratio (for xylenol orange) of 5 mM Gd-DOTA solutions spiked with GdCl3. Data is plotted as average fold change ± standard deviation, n = 6
