Chiral electrochemical recognition of tryptophan enantiomers at a multi-walled carbon nanotube–<i>N</i>-carboxymethyl chitosan composite-modified glassy carbon electrode

Abstract

A simple chiral electrochemical sensor based on <italic>N</italic>-carboxymethyl chitosan covalently binding with ethylenediamine-carboxylic multiwalled carbon nanotubes was developed for recognition of tryptophan enantiomers.
