Self-assembly between soft and nano materials allows the generation of new multiplexed drug delivery vehicles with good biocompatibility.In particular, graphene and liposomes are both promising materials for drug delivery applications.We found that nano-sized GO and zwitterionic liposomes can self-assemble to form complex nanostuctures.This talk will be divided into two parts.The first part is to understand the fundamental interactions between liposomes and graphene-based materials including graphene oxide (GO), reduced GO (rGO) arid pristinegraphene.
