Separation of tryptophan enantiomers with molecularly imprinted polypyrrole electrode column

In this study, we have fabricated molecularly imprinted polypyrrole (PPy) packed electrode columns and investigated their effects on separation of tryptophan (Trp) enantiomers by using potential control. The results indicate that the imprinted PPy electrode columns could efficiently enhance the L-Trp uptake and separate Trp enantiomers effectively, implying the great potential for the enantioselective recognition of other amino acids enantiomers.
