ICG-conjugated Magnetic Graphene Oxide for Dual Photothermal and Photodynamic Therapy.

ABSTRACT: Aptamer-functionalized magnetic graphene oxide conjugates loaded with indocyanine green (ICG) dye, or Apt@ICG@mGO, have been successfully developed for dual-targeted photothermal and photodynamic therapy. In general, a drug or its carrier or their dosage can be imprtant important issues in terms of toxicity. However, in this system, each component used is quite safe, biocompatibe and clean. For instance, ICG, a Food and Drug Administration (FDA) approved near-infrared (NIR) dye, serves as both a photothermal and photodynamic agent. It is immobilized on the surface of mGO via a physical interaction called "π-π stacking". The mGO, as a most biocomptible member of the carbo family, is selected for use as a platform for aptamer and ICG dye conjugation, as well as as a photothermal agent. The l
