89Zr chelator-free labeling. a) Time-dependent 89Zr labeling yields of WS2/WOx (0.4)-PEG nanodots without / with EDTA or DFO competitive reaction. b) Autoradiograph of TLC plates of 89Zr-WS2/WOx (0.4)-PEG nanodots (left) and free 89Zr (right). c) Time-dependent 89Zr labeling yields of WS2-PEG and different WS2/WOx-PEG nanodots (WS2/WOx (0.1), WS2/WOx (0.25), and WS2/WOx (0.4)) with EDTA competitive reaction. d) Serum stability study of 89Zr-WS2/WOx (0.4)-PEG nanodots incubated in whole mouse serum without or with DFO competitive reaction at 37 °C.
