V.P. Wallace, PE. Taday, A.J. Fitzgerald, R.M. Woodward, J. Cluff, P.J. Pye and D.A. Arnone, Terahertz pnlsed imaging and spectroscopy for biomedical and pharmaceutical applications, Faraday Discuss., 126, 255-263 (2004). 

Brighter, tunable ultrafast light sources would benefit many of the areas discussed in the report, particularly infrared-terahertz (between visible light and radio waves) vibrational and dynamical imaging, near-field scanning optical microscopy (NSOM), and X-ray imaging. 

THz sensing and imaging technology is relatively new with numerous applications from sectors as diverse as semiconductor, medical, manufacturing, space, and defense industries. In this chapter, a broad survey of terahertz-biodetection technology from its infancy to more recent biomedical use is presented. The focus is directed mainly on terahertz radiations that can be specifically applied to label-free ligand-analyte interaction. The uniqueness, limitations, and potential capabilities of THz biosensor are discussed.
