Paper Abstract

THz-technology provides new ground for label-free detection of biomolecules by taking advantage of existing hybridization techniques. Recent developments for label-free analysis of genetic material with femtomol-sensitivity using integrated functionalized THz sensors are presented. In comparison to former planar strip line approaches, the modular concept based on parallel-plate waveguides presented here provides a cost-efficient solution given the exchangeability, disposability or reusability of components. Three different fabrication technologies for disposable THz resonator chips are investigated.
