(A) Scheme for the synthesis of QD705-RGD, in which PEG represents poly (ethylene glycol) with molecular weight of 2000. (B) Serial in vivo imaging of U87MG tumor-bearing mice after intravenous injection of QD705-RGD (left) or QD705 (right). QD fluorescence is color coated red and mouse autofluorescence is color coded green. Arrows indicate tumors. Adapted from [81].
