Abstract
The present invention is a stable, nanometer scale micro-tubular aggregated material of an asymmetric double-headed lipid represented by the general formulaR—NHCO—(CH)—COOH  (I)(in the formula, R represents an aldopyranose radical from which the terminal reducing hydroxyl group is excluded and n is from six to twenty). The external diameter of the micro-tubular aggregated material is 10-300 nm, and the length is 0.3-10 μm. The micro-tubular aggregated material can be manufactured by dispersing the asymmetric double-headed lipid described above in water at pH of two to eight, next heating to 80-100° C. to dissolve it and then gradually cooling the aqueous solution obtained.
