Biomedical is one the applications of terahertz waves. This pages show some results in this topic, mainly in the framework of the DFG NearSense projet.
This paper present the terahertz near field resonator developed in the framework of Nearsense project and pulse time domain images used to determine the best frequency and design the resonator.

We This paper presents a fully-integrated 0.56 THz 128-pixel near-field 1-D sensor array with 10-12 μm lateral resolution. The sensing elements are based two parallel cross-bridged split-ring resonators that utilize a 3-D topology to exhibit high field confinement in the sensing spot. The sensor comprises a scalable excitation scheme that is designed to maximize the…
In the course of in vitro studies of blood of laboratory animals with progressing Ehrlich carcinoma, we have revealed the change of the blood plasma optical properties in the THz range, which can be used for developing the express diagnostics of the presence of oncological diseases. An applied software package is elaborated that allows the…
In this review, we describe dielectric properties of biological tissues and liquids in the context of terahertz (THz) biophotonics. We discuss a model of the THz dielectric permittivity of water and water-containing media, which yields analysis of the relaxation and damped resonant molecules modes. We briefly describe modern techniques of THz spectroscopy and imaging employed in biophotonics with a strong emphasize on a…
