The objective is to easily introduce a desired functional substance into organic nanotubes under milder conditions such as ambient temperature and ambient pressure. The method comprises the steps of allowing a surface active organic compound comprising hydrophobic hydrocarbon groups and hydrophilic groups to self aggregate in liquid phase to form organic nanotubes having an internal cavity size of at least 5 nm (step 1), freeze drying the organic nanotubes (step 2), dissolving or dispersing a desired functional substance in a solvent (step 3) and dispersing said freeze dried organic nanotubes in the solvent or the dispersion at or below the gel-liquid crystal phase transition temperature of said surface active organic compound (step 4). The organic nanotubes formed can be used in a variety of applications depending on the properties of the functional substance.
