Synthesis of Graphene-based Nanomaterials for Photo-Thermal Therapy

Graphene with unique two-dimensional structures, fascinating electronic, physical and chemical properties has shown promise in a wide range of fields including electronic devices,solar cells, nano-catalysts, as well as chemical and biological sensors [1]. Recently, tremendous attentions have been paid tothe graphene based nanomedicine for biological detection, drug delivery, and cancer therapies [2]. Hydrophobicity of graphene restricts its application innanomedicine. In order to improve its water solubility, graphene should be modify by hydrophilic polymers [3]. On the other hand modified graphene has poly aromatic surfacestructure with an ultrahigh surface area which is available for efficient loading of aromatic molecule via π-π staking [4]. Inthis work we have used a new strategy to modify graphene by polymers and deliver anticancer drugs by the resulted hybrid nanomaterials.
