چکیده
|
Herein, we report a simple approach for increasing the photothermal conversioneciency of gold rods (grs) as a result of interaction between gold rod and grapheneoxide. for preparation of these hybrid materials, gold rods were synthesized and modiedusing functionalized polyethylene glycol-triazine (peg-t). then functionalized gold rods(gr-p) were attached to graphene oxide (go) sheets by - stacking. it was found thatgr-p coating can improve the stability of go in aqueous solutions. moreover cellularexperiments 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 applicationin various biomedical elds such as photothermal cancer therapy.
