) reached 2.26, and the detection limits for L- and D-Trp were calculated to be 6.67 and 16.1 μM, respectively. The higher DPV result for L-Trp was attributed to its higher affinity for the chiral selectors D-PANI and β-CD-MOF than that of D-Trp. Moreover, the proposed chiral sensing platform could be used for analyzing the percentage of D-Trp in enantiomer mixed solutions and human urine samples with satisfactory recoveries.
