A multi-functional probe to discriminate Lys, Arg, His, Cys, Hcy and GSH from common amino acids

Abstract

The co-existence and similar properties of amino acids make the detection of individual amino acids challenging. Herein we discovered that probe 1 may act as a smart example to classify and differentiate basic amino acids (Arg/Lys/His), thiol-containing amino acids (Cys/HCy), and GSH through different sensing mechanisms in selected environments.
