(A) TEM image and (B) absorbance and fluorescence emission spectra of InAs/InP/ZnSe core/shell/shell nanoparticles dispersed in chloroform, showing that the size of QDs is about 5 nm in diameter with the maximum emission peak at about 800 nm. (C) DLS analysis of QD800-PEG, QD800-RGD, and QD800-RAD with the HDs in PBS buffer of 16.5 nm, 19.6 nm, and 20.1 nm, respectively. (D) Circulation half-life analysis of QD800-PEG in nude mice, showing that the half-life of QD800-PEG is 29.0 ± 9.1 min.
