▎ 摘　　要

NOVELTY - The sensor has a silver film layer fixed with a polishing surface of a D-type optical fiber. A graphene thin film layer is arranged on the silver film layer. Thickness of the graphene thin film layer is 1-10 nm. Thickness of the silver film layer is 10-80 nm. USE - Graphene thin film sensitivity D-type optical fiber SPR sensor for use in biology, chemistry and medicine detection fields. ADVANTAGE - The sensor is small in size and light in weight, and ensures quick response. The sensor has wide application range. The sensor can detect micro-gas, liquid, chemical elements and DNA. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a graphene thin film sensitivity D-type optical fiber surface plasmon resonance (SPR) sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene thin film sensitivity D-type optical fiber SPR sensor.
