Key Points

The electrochemical probe effectively identifies tryptophan isomers, enhancing chiral detection.
The study notes that d-Trp exhibits a larger current peak than other isomers due to its unique properties.
The method employs carbon dot/chitosan composites in a portable sensor for effective results.
This approach may streamline chiral identification in various applications, highlighting potential uses in biotechnology.

Implication

Portable electrochemical detection reveals differing currents of tryptophan isomers, suggesting effective chiral identification.

Abstract

A portable strategy for the electrochemical chiral detection of Trp based on CD–CS/CB/GCE sensor was described. The larger current peak of d -Trp was attributed to the lower affinity and easier permeation of d -Trp to the surface of the electrode.
