▎ 摘　　要

NOVELTY - Method for manufacturing a graphene composite structure, comprises forming a support body having an observation unit corresponding to an observation area and a frame unit disposed on an edge of the observation unit, forming a graphene layer on an upper surface of the observation unit, physically contacting an organic elastic member with the upper surface of the graphene layer to transfer organic components to the upper surface of the graphene layer, and forming a hydrophilic protective layer on an upper surface of the graphene layer by applying energy to the graphene layer onto which the organic component is transferred. USE - The method is used for manufacturing a graphene composite structure (claimed). ADVANTAGE - The method provides hydrophilicity to graphene layer on which biological sample is placed, and at the same time reduces self-luminescence in observation unit to achieve high magnification of biological sample, manufactures graphene composite structure modified with a hydrophilic surface without damaging inherent electrical characteristics of the graphene layer, and analyzes sample with high magnification and high definition by reducing autofluorescence that acts as noise during image analysis of sample. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene composite structure comprising a support body including an observation unit corresponding to an observation area and a frame unit disposed on an edge of the observation unit, a graphene layer disposed on an upper surface of the observation unit, and a hydrophilic protective layer formed on the upper surface of the graphene layer, where the hydrophilic protective layer transfers organic components to the upper surface of the graphene layer by physically contacting an organic elastic member with the upper surface of the graphene layer, and the organic component is formed while being modified by the energy applied to the graphene layer transferred into it.
