(A) Percentage of DEX and betamethasone (BTZ) bound to polymer 10 after 7 min of incubation, expressed relative to the initial analyte concentration of 5.0 × 10⁻⁵ M. (B) Percentage of DEX and BTZ bound to polymer 10 after 2 h of incubation, expressed relative to the same initial analyte concentration. In each experiment, 10 mg of sorbent was incubated with 3 mL of analyte solution. All experiments were performed in triplicate (n = 3), and error bars represent ± SD. * Indicates a statistically significant difference between each MMIP and its corresponding MNIP (unpaired two-tailed t-test, p < 0.05).
