RESUMO
Its extraordinary self-assembly property, with potential to form nonperiodic structures with unique addressability, makes DNA ideal for fabrication of advanced nanostructures. We here demonstrate the controllable tethering of a hexagonal DNA nanostructure in two distinct orientations at the lipid bilayer of a liposome functioning as a soft-matter support. With polarized light (linear dichroism) applied to the flow-aligned liposomes, we show that the construct is preferentially in a parallel alignment with the lipid surface when two anchors are attached while with one anchor only a perpendicular orientation is observed.
