We report on our recent progress in the development of a device for light-matter interaction enhancement in the full terahertz range for precise spectroscopy of minor-volume samples. The efficient confinement of a broadband terahertz pulse to a few-nL-volume was achieved, opening new perspectives for chemical and biological applications. We discuss modifications in the fabrication process leading to the improvement of our technique, following the detailed characterization of the device performances.
