Unlike the crude study conducted at the beginning of nanomedicine, researchers have devoted more efforts to developing nanosystems with elaborated structures and multifunctions owing to the fact that the tumor microenvironment is complicated. However, it is still a great challenge to prepare these nanoplatforms for drug delivery. In this study, multifunctional prodrug nanocarriers were fabricated by the modularized host-guest selfassembly between cholesterol and β-cyclodextrin. The targeted ligand lactobion...
