Graphene research and applications

Loading and delivery of Bcl-2-targeted short interfering RNA (siRNA) and anticancer drug doxorubicin (DOX) by polyethylenimine (PEI)-conjugated graphene oxide (PEI-GO) is studied. A higher knockdown efficiency of siRNA delivered by PEI-GO than by PEI is achieved. Sequential delivery of siRNA and DOX by the PEI-GO nanocarrier shows a synergistic effect, which leads to significantly improved chemotherapy efficacy.
