▎ 摘　　要

NOVELTY - The system has a graphene composite structure fixedly arranged on a to-be-measured surface for detecting stress and recognized molecule by using Raman spectroscopy. The graphene composite structure is connected with a detection device. The graphene composite structure is mutually provided with a flexible substrate, a graphene layer and a noble metal nano particle reinforced layer. The detection device is provided with an excitation light source and a spectrometer. The excitation light source provides excitation light for exciting graphene and to-be-tested molecule. USE - Stress graphene composite structure based molecular detection and recognition system. ADVANTAGE - The system can determine a plane moving tissue detection point, realize tissue surface two-dimensional stress sensing measurement and graphene to transmission form different molecules in tissue based on molecular recognition and effectively detect a graphene scattering signal and small molecule based on tissue repair condition comprehensive detection so as to improve molecular detection and recognition efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a stress graphene composite structure based molecular detection and recognition system.
