A Highly Sensitive and Selective Turn‐On Fluorogenic and Chromogenic Sensor Based on BODIPY‐Functionalized Magnetic Nanoparticles for Detecting Lead in Living Cells

Abstract

A new fluoro-chromogenic chemosensor based on BODIPY-functionalized Fe(3)O(4)@SiO(2) core/shell nanoparticles 1 has been prepared. Chemosensor 1 exhibits a high affinity and selectivity for Pb(2+) over competing metal ions tested. Moreover, confocal microscopy, and flow cytometry experiments established that 1 can be used for detecting Pb(2+) levels within living cell.
