Abstract

Graphene Oxide (GO) is an oxidized form of graphene, containing functional groups exposed all over its surface expanding the capacity to link drugs and other functional molecules through noncovalent/covalent interaction. Therefore, GO can be considered an appropriate platform, since it can easily physically absorb cationic charged dye compounds via strong p-p and electrostatic interaction on its surface resulting on the formation of GO-dye composite. GO is basically composed of carbon than it can be considered relatively biocompatible, being a suitable candidate for biological applications as well. We associated GO with a photosensitizer for photodynamic therapy. UV-vis spectroscopy and fluorescence emission measurement were used to characterize this system.
