A highly efficient chiral sensing platform for tryptophan isomers based on a coordination self-assembly

Construction of convenient and effective method for enantiomer identification is of vital significance for biochemistry and medical science. Herein, we design an effective sensor for chiral recognition of tryptophan (Trp) enantiomers, and self-assembly of Cu2+-modified β-cyclodextrin on poly-L-arginine/multi-walled carbon nanotubes (Cu-β-CD/PLA/MWCNTs) is studied. Meanwhile, Cu2+ acts as a cap to prevent the release of the high energy water and...
