BODIPY modified silica coated magnetite nanoparticles as fluorescent hybrid material for Cu (II) detection in aqueous medium

摘要

A novel ratiometric fluorescent sensor for copper II based on silica coated magnetite hybrid fluorescent material functionalized with boron-dipyrromethene containing a di (2-picolyl) amine was prepared and characterized. The binding abilities of the functionalized silica coated magnetite nanoparticles towards different metal ions have been examined by fluorescence spectroscopy, and displays high selectivity and sensitivity for Copper II among the all tested metals in Ethanol/water: 8:2.
