NOVELTY - Use of graphene-embedded carbon film material is claimed in tumor cell detection and analysis, involves capturing and or releasing tumour cell by graphene-embedded carbon film substrate. The tumor cell is analyzed. USE - Graphene-embedded carbon film material in tumor cell detection and analysis. ADVANTAGE - The graphene-embedded carbon film material has high specificity capturing circulating tumor cell, at the same time it can not introduce foreign substance such as enzyme or gold nano- particle dissolved gelatin under the premise of realizing self-heating by substrate under the near- infrared light irradiation to release the cell so as to subsequent biological analysis.
