Fig. 4: Binding selectivity and binding affinity of hydrogel DNA–UEH to uranyl.
From: DNA nano-pocket for ultra-selective uranyl extraction from seawater

a Adsorption capacity to 100 times concentrated coexisting interfering ions in natural seawater. b Binding selectivity to 100 times concentrated coexisting interfering ions. c Competition to individual interfering metal ion. c Binding affinity to uranyl against carbonate group. The error bars indicate standard deviation (n = 3). (Source data for A and D provided in source data file).
