▎ 摘　　要

NOVELTY - The chip has a sensor chip base body (1) provided with a high refractive index prism. An upper side of the sensor chip base body is orderly plated with a medium Cytop layer (2) and a semiconductor TDBC film (3), where thickness of the semiconductor TDBC film is 2-5 nm and thickness of the medium Cytop layer is 1800-2200 nm. The semiconductor TDBC film is coated with a graphene layer (4), where thickness of the graphene layer is less than or equal to 1.7 nm. USE - Graphene modifying-type long-range surface plasma resonance sensor chip. ADVANTAGE - The chip has high sensitivity and stable response signal characteristics. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene modifying-type long-range surface plasma resonance sensor chip.
