Abstract
An important feature of terahertz imaging/spectroscopy arises from its low-energy photons, which are well below the ionization energy of biomolecules. In Chap. 10, an overview of terahertz waves is presented, and their significance for biomedical imaging and sensing applications as well as their interactions with biomolecules are explored. Additionally, various biomedical imaging techniques are compared, considering different potential parameters. These medical imaging techniques provide a reasonably good spatial resolution of less than a few hundred microns. Furthermore, the diffraction-limited resolution is also maintained even in biological cells and tissues because the dimensions of cells are comparable to or smaller than the wavelength of terahertz waves. Moreover, the millimetre and terahertz biosensors and their sensing techniques and potential scopes are presented in detail. Finally, a summary of the chapter and future research directions are presented.
