Figure | Design and operation of the on-chip THz metasensor. a, The metasensor integrates THz generation, THz-molecule interaction, and signal detection on a single platform. The metasurface converts the guided THz wave into a surface-confined spoof surface plasmon polariton mode, enhancing its interaction with analytes for fingerprint sensing. b, Samples are deposited onto the metasensor by drop-casting and drying. The insets show the molecular structures and fingerprint spectra of the four representative biomolecules and their mixture. c, Photograph of the fabricated metasensor alongside a one-yuan coin for scale.
