摘要：
We developed terahertz time-domain sensing and imaging platforms for highly sensitive and selective molecule detection in very low concentration. Highly sensitive sensing performance was obtained by various designs of nanoscale metal resonators and their lateral pattern array. Small quantity of target biomolecules was detectably assisted by resonance behavior and huge terahertz field enhancement at the near-field regime. Further studies with large area metamaterial sensing chips represented great promise as a two-dimensional imaging sensor with high contrast and efficient discrimination.
