From: Are quantum dots ready for in vivo imaging in human subjects?
Different surface coating of QDs results in different in vivo kinetics. mPEG-750 coated QDs circulates much shorter than mPEG-5000 coated QDs. Even at 1 min, significant liver uptake of mPEG-750 QDs is visible. At 1 h, mPEG-750 QDs completely cleared from the circulation while mPEG-5000 QDs persisted. From [151]
