Culture medium

摘要

A culture medium is used for culturing neural cells. Each neural cell includes a neural cell body and at least one neurite branched from the neural cell body. The culture medium includes a substrate and a carbon nanotube structure located on the substrate. The carbon nanotube structure includes a number of carbon nanotube wires spaced apart from each other. A distance between adjacent carbon nanotube wires is greater than or equal to diameters of the neural cell bodies. The carbon nanotube wires are capable of guiding extending directions of the neurites.
