Development of near-infrared region luminescent N-acetyl-L-cysteine-coated Ag2S quantum dots with differential therapeutic effect

What is it about?

NAC is a wellknown antioxidant and may be used to reverse quantum dot based toxicity. NAC coated Ag2S QDs in small size with strong emission in the medical imaging window were synthesized. In vitro studies indicate that lung based cells internalize these QDs more than MCF7 and HeLA. In vitro studies performed with MCF7 showed that NAC-Ag2S induce ROS reduction but also DNA damage which caused apoptotic cell that.
