Polymer/Graphene Hybrid Nanomaterials are able to Deliver Paclitaxel, in Spite of Carbon Nanotubes!

Graphene has stimulated an enormous research interest in recent years due to its excellent mechanical, electrical, thermal and optical properties. Due to its very high surface area,graphene oxide (GO) is one of the most important graphene derivatives and has been extensively studied in recent years[1]. In particular, GO is a potential candidate for biological applications, such as drug delivery and bio-analysis [2]. Hydrophobicity of graphene restricts its application innanomedicine. In order to improve its water solubility, graphene should be modified by hydrophilic polymers[3] . In this work the ability of graphene sheets in order to deliver paclitaxel anticancer drug has been proved
