Abstract:

The recent progress of the photothermal effect of graphene/organic conjugated system was summarized. Although organic photothermal agents exhibited high photothermal conversion efficiencies and excellent biocompatibilities, their low photo-stabilities restricted their real applications. Recently, some reports indicated that graphene could improve the photo-stabilities and enhance the photothermal conversion efficiencies of organic conjugated molecules. In addition, multiple functions, such as photoacoustic imaging-guided photothermal therapy, pH responsive fluorescence imaging-guided photothermal therapy, and chem-photothermal therapy, can be integrated into the graphene/organic conjugated system, which plays an important role in the field of photothermal therapy. This review article summarizes the recent progress of the photothermal effect of graphene/organic conjugated system, and will be useful for the development of the photothermal effect of graphene/organic conjugated system.

Key words: graphene, organic dye molecules, conjugated polymers, photothermal effect, photothermal agents
