Chiral ligand exchange potentiometric aspartic acid sensors with polysiloxane films containing a chiral ligand N-carbobenzoxy-aspartic acid.

Abstract

An enantioselective molecular sensor was fabricated by inserting a chiral ligand, N-carbobenzoxy-L-aspartic acid (N-CBZ-L-Asp) or N-CBZ-D-Asp, into an octadecylsiloxane (ODS) monolayer by polysiloxane film immobilization (PFI). The resulting system can recognize one enantiomer of aspartic acids (Asps) due to the chiral ligand exchange reaction at the N-CBZ… (More)
