Nanotechnology for Nanodevices in Polymer

The generation of three-dimensional (3D) nanostructures in polymer through the utilization of nanoimprint and dry etching technologies allows for precise control of multiple layers of 3D devices with nanometer dimensions. These nanofabrication technologies provide devices with advanced functionalities, and they also have the advantages of having high speed, high uniformity, and high reproducibility. These nanostructures are crucial for the development of high-performance biosensors, metadevices, and terahertz (THz) devices.
In this presentation, we will showcase how nanoimprint technology can be utilized to create unique 3D nanostructures that can be applied to various nanodevices. For instance, plasmonic biosensors with 3D asymmetrical designs will be presented to demonstrate their high sensitivity in monitoring cells and biomolecules. Furthermore, cell migration behaviors can be regulated on platforms with nanostructures, and the 3D platforms can be used to separate cancer cells from normal cells. Demonstrations of multiple layers of nanostructures with twist angles will be presented to form chiral magic angles for light manipulation. Additionally, the utilization of curved or metasurfaces will be highlighted to showcase the development of high-performance THz lenses and antennas with beam control.
