Plasmonics and metasurfaces for sensing and imaging

Plasmonics nanostructures and dielectric metasurfaces have found diverse applications in the areas of chirality-based biochemical sensing (Advanced Materials 32 (41), 1907151, 2020), high-resolution optical imaging with non-diffracting, self-accelerating Bessel beams (Laser & Photonics Reviews 15 (5), 2000487, 2021) and Airy beams (ACS Nano 15 (1), 1030-1308, 2021).
In 2014, we and co-workers demonstrated the design and preparation of a hierarchical porous plasmonic metamaterial, which gives rise to highly reproducible ultrasensitive surface‐enhanced Raman scattering (SERS, (Advanced Materials 27 (6), 1090-1096, 2015). This work represents one of the few pioneering attempts in applying the hierarchical metamaterial concept to address the long-standing issues of SERS – reproducibility and sensitivity, and was selected as an ESI^SM Highly Cited Paper (Top 1% in the academic field of Materials Science for its publication year).
Our research results on SERS-based biochemical sensing (Journal of Physical Chemistry Letters 10 (16), 4692-4698, 2019; Nanoscale 6 (15), 9063-9070, 2014; Journal of Applied Physics 114 (12), 124305, 2013), plasmonic nanorulers ( ACS Nano 8 (9), 9188-9198, 2014) and phase-changing tunable SERS (Advanced Optical Materials 10 (8), 2102615, 2022) have been well recognized by the plasmonics SERS community, for which we have been invited to contribute a chapter to the book entitled "Recent Developments in Plasmon-Supported Raman Spectroscopy: 45 Years of Enhanced Raman Signals", edited by K. Kneipp, Y. Ozaki and Z.-Q. Tian, World Scientific Publishing, 2018.
