Abstract :

Metasurfaces, engineered planar structures with tailored electromagnetic responses, have emerged as a powerful platform for compact and high-sensitivity sensing systems. This talk explores recent advancements in using metasurfaces for label-free biosensing at microwave and terahertz frequencies. We focus on metasurface designs featuring high-quality-factor resonators that enhance light-matter interaction at the surface, enabling real-time, non-invasive detection of biomolecular changes. Applications include glucose monitoring and detection of disease biomarkers, using both substrate-supported and free-standing architectures fabricated through scalable methods such as laser micromachining. These designs offer high field confinement, sharp resonance features, and compatibility with miniaturized, in vivo sensing platforms, positioning them as strong candidates for the next generation of diagnostic technologies.
