Method for forming nerve graft

摘要

A method for forming a nerve graft includes the following steps. A carbon nanotube structure is provided. A hydrophilic layer is formed on a surface of the carbon nanotube structure. The hydrophilic layer is polarized to form a polar surface on the hydrophilic layer. A number of neurons are formed on the polar surface of the hydrophilic layer to form a nerve network. The neurons connect with each other.

1. A method for forming a nerve graft, comprising:
providing a carbon nanotube structure; evaporating or sputtering an inorganic material on a surface of the carbon nanotube structure to form a hydrophilic layer; soaking the hydrophilic layer with a polyamino acid solution or a polyetherimide solution to polarize a surface of the hydrophilic layer to a polar surface, wherein the soaking the hydrophilic layer with the polyamino acid solution or the polyetherimide solution comprises sub-steps of:
providing a supporter;placing the carbon nanotube structure having the hydrophilic layer on a surface of the supporter; andsoaking the hydrophilic layer on the carbon nanotube structure on the surface of the supporter with the polyamino acid solution or the polyetherimide solution to polarize a surface of the hydrophilic layer to a polar surface; andcompletely removing the polyamino acid solution or the polyetherimide solution from the polar surface; and seeding and culturing a plurality of neurons on the polar surface until adjacent neurons of the plurality of neurons are connected with each other, and the plurality of neurons form a nerve network.
