Fluorescent and Magnetic Mesoporous Hybrid Material: A Chemical and Biological Nanosensor for Hg(2+) Ions.

ABSTRACT: We introduce "sense, track and separate" approach for the removal of Hg(2+) ion from aqueous media using highly ordered and magnetic mesoporous ferrosilicate nanocages functionalised with rhodamine fluorophore derivative. These functionalised materials offer both fluorescent and magnetic properties in a single system which help not only to selectively sense the Hg(2+) ions with a high precision but also adsorb and separate a significant amount of Hg(2+) ion in aqueous media. We demonstrate that the magnetic affinity of these materials, generated from the ultrafine γ-Fe2O3 nanoparticles present inside the nanochannels of the support, can efficiently be used as a fluorescent tag to sense the Hg(2+) ions present in NIH3T3 fibroblasts live cells and to track the movement of the cells by extern
