As other reagents are needed in the cu rrent detection methods of antibiotic concentration,It is easy to cause interference to the experiment and affect the reliability of the measurement results.Therefore,a one-step transfer graphene metamaterial absorb er was proposed to characterize different concentrations of antibiotics.The graphene-metamateri al absorber heterostructure is sensitive to surface additions by transferring a single layer of chemically vapor deposited graphene onto the metamaterial absorber.the experiment result shows th at In the terahertz frequency band,the detection of antibiotics with different concentrat ions using graphene-metamaterial absorber heterostructure will cause different degrees of blue shift of resonance peak of graphene-metamaterial absorber heterostructure.The relationsh ip between resonance peak blue shift and concentration can be used to characterize differen t types and concentrations of antibiotics.
