We present the first observation of Janus nanoparticles consisting of stable, coexisting ordered mesophases in discrete particles created by lipid self-assembly. Cryo-TEM images provided visual identification of the multicompartment Janus nanoparticles and, combined with SAXS data, confirmed the presence of mixed cubic phases and mixed cubic/hexagonal phases within individual nanoparticles. We further investigated computer visualization models to interpret the potential interface between the interconnected coexisting nanostructured domains within a single nanoparticle.
