CDDP supramolecular micelles fabricated from adamantine terminated mPEG and β-cyclodextrin based seven-armed poly (l-glutamic acid)/CDDP complexes

► MPEG-Ad@β-CD-7PLGA/CDDP supramolecular micelles were fabricated. ► These micelles showed spherical shapes and negative zeta potentials. ► Their sizes were ranked at mPEG-Ad@β-CD-7P(LGA)10/CDDP < mPEG-Ad@β-CD-7P(LGA)15/CDDP < mPEG-Ad@β-CD-7P(LGA)20/CDDP. ► These micelles showed essential decreased cytotoxicity to KB cells, suggesting their great potential as the delivery carriers of CDDP.
