Abstract
A simple optical sensor for D/L aspartic chirals using Cd-based nanoparticles coated by β- cyclodextrine is presented. β-cyclodextrine modified Cd-based nanoparticles (CNP) were synthesized by a simple sonochemical technique. The characterizations of CNP were investigated by FT-IR, transmission electron microscope and fluorescence spectroscopy. CNP sensor works based on the selective host-guest interaction between aspartic and β-cyclodextrine combined with the quenching effect of photoluminescence of Cd-based nanopartciels. The results show the quench accorded with the Sternm – Volmer equation. The mechanism of sensor is discussed. The novel, simple and rapid sensing method exhibits an exceptionally limit of detection at 19 ng/mL of D-aspartic form.
