Abstract
⺠We developed a new facile method for transferring oil-soluble PbS QDs into water with glutathione. ⺠The resulting water-soluble GSH-capped PbS QDs show strong NIR fluorescence (PL QY >30%). ⺠We revealed the influence of ligand exchange with five different types of thiol molecules. ⺠We explored the conditions of QD water solubilization, the stability, and cytotoxicity. ⺠The resultant water-soluble NIR-emitting PbS QDs are promising for the imaging of living animals.
