Fund Project: This work was supported by NNSFC (No. 20335040, 20525519, 20605005) and TRAPOYT.

In this work, a novel method was constructed to determine the enantiomeric composition of tryptophan (Trp) by bovine serum albumin (BSA) based on the fluorescence spectra of the receptor-ligand mixtures coupled with partial least squares (PLS-1) analysis. As a result the enantiomeric composition of Trp was accurately determined.
- Bovine serum albumin,
- tryptophan,
- PLS-1,
- fluorescence spectrophotometry
