Herein, we report a simple approach for increasing the photothermalconversion efficiency of gold rods (GRs) as a result of between gold rod and graphene oxideFor preparation of these hybrid materials, gold rods were synthesized and modified using functionalized polyethylene glycol-triazine (PEG-T). Then functionalized gold rods (GR-P) were attached to grapheneoxide (GO) sheets by π-π stacking. It was found that GR-P coating can improve the stability of GO in aqueous solutions. Moreovercellular experiments showed that GR-P coating on GO induce remarkably reduced cell toxicity. Gold rod-graphene oxide (GR-P-GO) hybrid materials hold great promise for application in various biomedical fields such as photothermal cancer therapy.
