▎ 摘　　要

NOVELTY - Cell culture substratum (100) comprises substrate (110) and carbon nanowall (CNW1) formed on the substrate and having graphene sheet, where distal end (E1) of the graphene sheet in the carbon nanowall is a scaffold for culturing cells. USE - The substratum is useful for culturing cells (all claimed). ADVANTAGE - The substratum enables culturing of the cells such that cultured cells can be collected without damaging the cultured cells. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for cell culturing method, which involves using the above-mentioned substratum for culturing cells, where the carbon nanowall is used as substrate, and the distal portion of the graphene sheet in the carbon nanowall acts as scaffold for culturing the cells. DESCRIPTION OF DRAWING(S) - The drawing shows schematic block diagram of cell culture substratum. Cell culture substratum (100) Substrate (110) Carbon nanowall (CNW1) Distal end (E1) Base portion (R1)
