Owing to its effectiveness and security, photothermal therapy (PTT) has been recently established to be a promising cancer therapy after biological therapy, chemotherapy, radiotherapy and surgery. In this study, neogambogic acid reduced graphene oxide (NRGO) was prepared using a green and simple process. Which implies graphene oxide is reduced in situ and stabilized using neogambogic acid, a rich, cost efficient, sustainable biological material and all together forms NRGO. The resultant NRGO dissolves very well in water and displays effective biocompatibility because of the conjugation of neogambogic acid on the NRGO surface. This kind of NRGO's exhibit excellent photothermal abilities and were capable to destroy breast cancer (MCF-7) cells effectively with near-infrared 808 nm laser irradiation. These outcomes recommend that this form of NRGO hybrid material can be an assuring resource for upcoming applications of PTT.
