▎ 摘　　要

NOVELTY - The method involves preparing (S100) a hydrogel substrate that has a graphene oxide. A pattern structure is formed (S200) on the hydrogel substrate containing the graphene oxide by irradiating a femtosecond laser to the hydrogel substrate containing the graphene oxide. The graphene oxide contained in the hydrogel substrate is reduced (S300) on which the pattern structure is formed. The the pattern structure comprises a tissue structure mimic pattern. A femtosecond laser is irradiated which is having a frequency of 10 Hertz or more. The reducing solution comprises melatonin, amino acids, polyphenols or ascorbic acid. USE - Method for manufacturing a micropattern conductive hydrogel (Claimed). ADVANTAGE - The electrical signal exchange between cells becomes smooth, and it is possible to cultivate excellent cells. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart representation of method of manufacturing a micropattern conductive hydrogel.
