The ability to tune the nanostructure dimensions of the 𝑄 𝐼𝐼 𝑃 film by changing lipid composition, as we demonstrate here, extends the technological potential of the materials in different fields. The addition of CHOL and anionic lipids, such as DOPS, to MO systems can progressively increase the water channel size of the cubic phase in bulk materials . Recently, the same principles were applied to swell nanoparticle dispersions of bicontinuous cubic phases (cubosomes). This has potential for encapsulation of biological molecules and our current study enhances this potential by use of thin films of QII P phases, for surface encapsulation of for example linear molecules within its orthogonal straight channels. Meanwhile, control of the lattice parameter and water channel size of cubic phase films allows control over nanostructure dimensions of metals and other inorganic materials templated within them, as we have shown for 3D nanomaterials deposited within the QII D phase .
