Abstract: The present invention relates to a hybrid-type multi-lamellar nanostructure of an epidermal growth factor and a liposome and a method for manufacturing same. The new type of hybrid-type multi-lamellar nanostructure not only has a high epidermal growth factor encapsulating efficiency, but also can be manufactured through a simple process, such that the same can be easily delivered into a living body or a cell while maintaining a high physiological activity of the epidermal growth factor.
