Abstract
Nanotechnology is developed for a wide range of device and microsystem applications. The key requirements for nanotechnology, besides high resolution, are high uniformity over a large area and high reproducibility. Nanoimprint, dry etching, and conformal deposition are applied to generate high-performance devices and sensors. In this talk, we will show the results of applying three-dimensional (3D) asymmetrical nanopillars with sharp Fano resonance to detect low concentration cells, exosomes, and filipodia with high sensitivity. Using nanostructures on 3D platforms, cell migration behaviours can be controlled, and cancer cells can be separated from normal cells. Several low-profile, high-gain THz antennas with a concave cavity or two parallel dielectric metasurfaces will also be presented.
