Recent Progress on Terahertz Biosensors

Terahertz (THz) sensors are novel approaches to investigate biological processes and biomolecular recognition non-destructively in a label-free way. Recent research endeavors have focused on enhancing the sensitivity and practicality of THz sensors. This paper introduces the cutting-edge design methods of THz sensors, such as surface plasmon resonance, bound states in the continuum, electromagnetically induced transparency and so on. Some typical terahertz sensor designs are summarized to illustrate how to realize intelligent and multi-mode sensing.
