Electrochemical Chiral Recognizing Tryptophan Enantiomers Based on Chiral Metal-Organic Framework D-MOF

Isostructural chiral metal–organic frameworks with metal-regulated performances for electrochemical enantiomeric recognition of tyrosine and tryptophan

“…With a high current ratio, large potential difference and low LODs, Cu–TBLeuBpa@NF/GCE is an excellent sensing platform outperforming the most reported electrochemical sensors for the enantioselective recognition of Trp enantiomers. 36–38…”

“…The peak currents are linearly dependent on the logarithm of the concentration, and the LODs were calculated as 3.7 nM for L-Trp and 11.6 nM for D-Trp (3σ/k). With a high current ratio, large potential difference and low LODs, Cu-TBLeuBpa@NF/GCE is an excellent sensing platform outperforming the most reported electrochemical sensors for the enantioselective recognition of Trp enantiomers [36][37][38]. In contrast with Cu-TBLeuBpa@NF/GCE, Co-TBLeuBpa@NF/GCE shows almost identical DPV responses to…”
