Abstract
A method for making a nerve graft includes the following steps. A culture layer including a lyophobic substrate, a carbon nanotube film structure, and a protein layer is provided. The carbon nanotube film structure is sandwiched between the lyophobic substrate and the protein layer. A number of nerve cells are seeded on a surface of the protein layer away from the lyophobic substrate. The nerve cells are cultured until a number of neurites branch from the nerve cells and are connected between the nerve cells.
