Terahertz (THz) spectroscopy with nano-metamaterial chips offers rapid, label-free detection of biomaterials. This advanced technique enhances sensitivity for molecular interactions and virus quantification.

Area of Science:

  • Biophysics
  • Spectroscopy
  • Nanotechnology

Background:

  • Terahertz (THz) spectroscopy enables non-destructive, label-free, and non-contact analysis of biomaterials.
  • Protein-ligand binding interactions occur within the THz frequency range, making THz waves crucial for capturing conformational information.
  • Existing THz spectroscopy methods require enhancement for improved detection sensitivity.

Purpose of the Study:

  • To develop highly sensitive THz nano-metamaterial sensing chips for biomaterial detection.
  • To enhance the absorption cross-section and near-field interactions of target biomaterials using metamaterials.
  • To demonstrate the capability of the system for virus quantification and analysis of optical properties.

Main Methods:

  • Utilized terahertz time-domain spectroscopy (THz-TDS) combined with custom-designed nano-metamaterial sensing chips.
