strategy, the Janus dendron (Boc-G2L-G3L-OMe) was successfully modified with mPEG and PVGLIG-DOX via a two-step highly efficient copper-catalyzed alkyne-azide click cycloaddition (CuAAC) reaction. Morphology studies such as dynamic light scattering, scanning electron microscopy, and atomic force microscopy were performed to confirm that the Janus mPEGylated dendron-PVGLIG-DOX conjugate self-assembled into
