High-Yield Production of Water-Soluble MoS<sub>2</sub> Quantum Dots for Fe<sup>3+</sup> Detection and Cell Imaging

Uniform water-soluble MoS<sub>2</sub> quantum dots (WS-MSQDs) were synthesized via a sequential combination of sintering/etching/exfoliation method and solvothermal route. The obtained WS-MSQDs with average size of approximately 3.4 nm exhibited sufficient water solubility and remarkable...

description Uniform water-soluble MoS<sub>2</sub> quantum dots (WS-MSQDs) were synthesized via a sequential combination of sintering/etching/exfoliation method and solvothermal route. The obtained WS-MSQDs with average size of approximately 3.4 nm exhibited sufficient water solubility and remarkable fluorescence properties. The WS-MSQDs were utilized as a probe for detection of Fe<sup>3+</sup> ions with high selectivity and specificity. Furthermore, the WS-MSQDs exhibited high fluorescence stability under different conditions. Finally, the WS-MSQDs were successfully applied for the fluorescence imaging of Fe<sup>3+</sup> in living cells, which exhibited practical potential for biomedical applications.
