Illustration of the system after the insertion of RNA (colored spheres) into the CNT (black spheres). The CNT is embedded in a DMPC lipid bilayer. The whole system is solvated in a 1 M potassium chloride aqueous solution. In a cylindrical coordinate system (r, θ, z) the membrane is largely parallel to the (r, θ)-plane while the axis of the nanotube is nominally parallel to the z-axis.
