Method for preparing graphene oxide double-targeting medicine carrier material, and loaded medicine

The invention relates to a method for preparing a graphene oxide double-targeting medicine carrier material, and a medicine loaded by the carrier material. The method is used for preparing the carrier material and the loaded medicine. The invention solves the problems that the conventional nano-medicine carrier has a complicated structure, is high in synthetic cost and low in efficiency, and cannot be massively prepared easily. The method for preparing the graphene oxide double-targeting medicine carrier material comprises the following steps of: preparing carboxymethylated graphene oxide; preparing a graphene oxide-biologically targeting molecule composite; and preparing the graphene oxide double-targeting medicine carrier material, wherein the loaded medicine is one or more of doxorubicin hydrochloride, paclitaxel, hydroxycamptothecine and daunomycin.
