Study of supported phospholipid bilayers by THz-TDS

Hydration Shells of DPPC Liposomes from the Point of View of Terahertz Time-Domain Spectroscopy

“…When the reliable methods of the terahertz spectroscopy were designed, they triggered a wide usage of the technique in different areas of science, including biological studies. The structure of various biological macromolecules, such as proteins, 1,2 nucleic acids, 3,4 lipids, 5–7 etc., was analyzed by means of terahertz spectroscopy; attempts were made to apply it to biomedical studies. 8,9 These studies showed though that for biological samples with rich water content terahertz spectra predominantly reflect spectral properties of water itself, while contribution of biological matter is weak and bears little specificity.…”
