pH responsive smart carrier of [60] fullerene with 6-amino-cyclodextrin inclusion complex for photodynamic therapy†
Abstract
A new pH responsive smart carrier of C60 was prepared with 6-amino-γ-cyclodextrin (ACD) for photodynamic therapy. C60 was rapidly released from its inclusion complex with ACD at pH 6.7, due to electrostatic repulsion between ammonium groups, followed by a rapid C60 release at slightly acidic cancer cell surfaces.
