Preparation of fluorescent MoS2 quantum dots conjugated with various ligands, and its fluorescence imaging

Simple and ecofriendly hydrothermal method has been used to synthesize MoS2 quantum dots (QDs) with various ligands, L-glutothione (GSH), mercaptosuccinic acid (MSA), cysteamine (CYS), and monothioglycerol (MTG). Among them, GSH-MoS2 QDs demonstrated as an efficient fluorescence probe due to its smaller size, high fluorescence intensity, and good bio-compatibility.
