This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.Liposomes may be stably adsorbed or ruptured on graphene-based materials, depending on the oxidation state of graphene. IR-induced liposome leakage is achieved, since graphene oxide does not induce liposome leakage spontaneously.engrapheneliposomesadsorptioncontrolled releasecryo-TEMArticle
