Abstract
A sample signal amplification method using a terahertz band graphene absorber is provided. The method comprises: fabricating a graphene absorber through steps of metal evaporation, graphene transfer and the like; preparing sample solutions having different concentrations; dropwise adding a sample solution to the surface of the graphene absorber, and then drying in the air at room temperature; collecting terahertz time-domain signals of all sample points to be detected and reference sample points on the surface of the graphene absorber; and calculating absorption rates of all the sample points to be detected and the reference sample points according to the terahertz time-domain signals, and calculating the intensity change of an absorption peak according to the intensity value corresponding to the highest point of the absorption peak.
