Terahertz Spectroscopy of Mouse Blood Serum in the Dynamics of Experimental Glioblastoma

In this study terahertz (THz) absorption spectra of mouse blood serum in the dynamics of experimental U87 glioblastoma were investigated. Decrease of THz absorption with glioma growth was demonstrated. A two-component Debye model was used to analyze the experimental data. Analysis of the complex dielectric permittivity parameters of blood serum indicates an increase in the proportion of bound water in the samples in the dynamics of tumor growth.
