Complex structures are ubiquitous in biological systems. Over millions of years, biological systems have evolved optimized functions based on their unit cells' beneficial size and material effects that contribute to favorable mechanical and physical properties. Inspired by these biological systems, many trial-and-error reverse-engineering and computational methods have been utilized to mimic these structures for various applications, such as light management, flexible sensing, wetting control, adhesion, and electrocatalysis. One of the most challenging is manufacturing man-made systems with controllable features spanning multiple length scales, particularly down to the nanoscale, which seriously impacts the system's collective properties. In this presentation, I will introduce a new concept of aluminum-based 3Dlithography (AL-3Dlitho) enabled by the aluminum surface work hardening phenomenon. Then, I will talk about the design and fabrication of plasmonic metasurfaces via AL-3Dlitho, as well as the applications for biosensor and optoelectronic devices, which could fully utilize customized multiscale structures on different length scales to demonstrate superior performances.<br/><br/>References:<br/>(1) Wen L.Y.*, et al., ACS Nano 17, 22, 22766, 2023<br/>(2) Wen L.Y.*, et al., Advanced Science, 2206236, 2023<br/>(3) Wen L.Y.*, et al., Advanced Optical Materials, 202300508, 2023<br/>(4) Wen L.Y.*, et al., Nano Lett. 22, 9982, 2022<br/>(5) Wen L.Y., et al., Nature Nanotechnology, 12, 244, 2017<br/><br/>Short Bio:<br/>Liaoyong Wen received his PhD degree in Applied Physics from the Technical University of Ilmenau, Germany.
