▎ 摘　　要

NOVELTY - The detection system has an optical fiber (2, 4) for detecting the excitation light from an excitation light source (1). A graphene layer (7) is provided on the end face of the optical fiber. The graphene Raman light is detected by the Raman scattered light returned from the optical fiber Raman spectrum of a Raman spectrometer (9). The Raman spectrometer is used for detecting the fiber end faces between the graphene layers which are provided with noble metal nano particles. USE - Online detection system of tumor using Raman scattering technique. ADVANTAGE - The size of the tumor cell growth force is determined and the sensitivity of detection of the tumor cell is improved. The diameter of the fiber is made small and is inserted into body for tumor detection. The detection of the original position is displayed in real-time. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of online detection system of tumor using Raman scattering technique.
