▎ 摘　　要

NOVELTY - Method for inducing growth of nerve cells involves (a) providing a graphene oxide layer, (b) selectively irradiating a laser in a desired pattern with respect to the graphene oxide layer, where the laser provides energy to reduce at least a portion of the graphene oxide in the irradiated pattern region and surface roughness is formed in the pattern region of the reduced graphene oxide, and (c) attaching and growing nerve cells to the pattern region of the reduced graphene oxide. USE - The method is useful for inducing growth of nerve cells chosen from hippocampal neurons, spinal motor neurons, dorsal root ganglion, retinal ganglion neurons, Golgi I neurons, Golgi II neurons, basket cells, betz cells, lugaro cells, medium spiny neurons, Purkinje cells, Renshaw cells, unipolar brush cells, granule cells, anterior horn cells, motoneurons, spindle cells, pseudounipolar neurons, multipolar neurons, interneurons, motor neurons, sensory neurons, stellate cells and their combinations (claimed). The method is useful in bioelectronic devices such as carbon-based nerve chips and neural prostheses. ADVANTAGE - The method induces growth of nerve cells in a simple and cost-effective manner with reduced manufacturing processes.
