Terahertz bio-sensing techniques
J.-H. Son, University of Seoul, Republic of Korea
Abstract:
This chapter reviews research involving the sensing and analysis of biological materials using terahertz (THz) waves. Because the characteristic energy of biological materials, generated by molecular motions such as rotation and vibration, lies in the THz frequency range, THz spectroscopy is the best tool for the direct sensing of biological molecules and the associated techniques. This review begins with water, outlining its bulk dielectric property and the temperature dependence thereof, and its solvation dynamics in the presence of various solutes including proteins. THz techniques have also been used to study the dynamic behaviour of proteins, ...
