Magnetic Nanostructures for Selective Detection of Zinc Ions in Aqueous Solutions

Abstract

This thesis reports on the synthesis and characterization of novel magnetic nanostructure fluorescent chemosensors and their potential applications in sensing and detection of zinc ion in aqueous solutions. The nanostructures obtained in this study were carefully designed by employing a core-shell approach which was advantageous by offering stability, hydrophilicity and recoverability. The photophysical properties: sensitivity, selectivity and pH dependence were determined. The nanochemosensors were able to sense Zn2+ ion with a very low detection limit.
