Abstract

The fabrication of organic–inorganic hybrid nanotubes organized into concentric layers is described. Self-assembly of glycolipids inside the confined nanospace of hollow cylindrical silica nanotubes produced a hybrid nanotube consisting of two concentric layers, one of silica and one of lipid. Addition of glucopyranosyl ammonium cation induced concomitant self-assembly of lipid layers on both the inner and the outer surfaces of the silica nanotube, producing hybrid nanotubes with concentric lipid–silica–lipid walls. Subsequent sol–gel reaction using these lipid–silica–lipid nanotubes resulted in the formation of more complex hybrid nanotubes with a concentric five-layered structure of silica–lipid–silica–lipid–silica. Scanning transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray analysis, and Fourier-transform infrared spectroscopy were used to confirm the formation of the concentric alternating layers of organic and inorganic materials in the hybrid nanotubes.
