Abstract

Gadolinium-doped ZnSe (Gd:ZnSe) quantum dots (Qds) were synthesized using ethylene glycol as a stabilizing agent. The fluorescence spectrum exhibited an emission peak at 435 nm for ZnSe, whereas the Gd-doped ZnSe exhibited a green emission at 547 nm. In vitro imaging studies of MCF-7 cancer cells were carried out using fluorescent probes constructed using Gd-ZnSe folate.
