Schematic representation of QD targeting. Intravenous delivery of QD into specific tissues of the mouse. (Upper) Design of peptide coated QD. (Lower) QD were coated with either peptides only or with peptides and PEG.PEG helps the QD to maintain solubility in aqueous solvents and minimize nonspecific binding [65].
