Cortex formation with RNA origami nanotubes on the inner GUV membrane. Left: schematic representation of an RNA origami nanotube adhering to the biotinylated GUV membrane via a biotin aptamer attached to the iSpi tile 38 . Right: confocal 3D reconstruction of an RNA origami cortex on the inner GUV membrane after its expression. Scale bar, 10 μm.
