Electrochemical chiral recognition of tryptophan enantiomers by using chiral polyaniline and β-CD-MOF

Chiral detection of tryptophan (Trp) isomers is of vital importance and the introduction of efficient, stable and sensitive enantioselective recognition technology is in high demand in the fields of medicine, food and life science. Herein, a facile and sensitive electrochemical probe for the chiral recognition of Trp enantiomers by using chiral polyaniline (D-PANI) and β-CD-MOF is presented. The structure and electrochemical performance of the designed sensor (GCE/β-CD-MOF/D-PANI) were characterized
