Entirely oligosaccharide-based supramolecular amphiphiles were constructed via host-guest interactions between ferrocene-terminated acetylated-maltoheptaose (Fc-AcMH) and β-cyclodextrin-terminated four-arm star maltoheptaose (MH-β-CD). The amphiphiles could self-assemble to form spherical supramolecular nanoparticles to provide efficient drug delivery platforms. The combination of a pH-sensitive covalent acetal group and the oxidation-sensitive noncovalent host-guest interaction of β-CD and ferrocene provided the obtained fully oligosaccharide-based supramolecular amphiphiles. The structures of these amphiphiles could respond to the intracellular microenvironment.
