Plasmonic Nanomaterials: from Paper Sensor to Cancer Therapy

Abstract

    Plasmonic metal nanostructures (e.g., Au, Ag) have proven to be a versatile platform for a broad range of optical applications. They are attractive for their surface plasmon resonance (SPR) properties. The strong interactions between metallic nanoparticles (NPs) and incident light originate from excitation of the collective oscillations of conduction electrons within these particles. In this talk, I will introduce our recent work on the fabrication of metal nanostructures, and their optical properties as well as sensing applications. First part illustrates a paper-based plasmonic refractometric sensor through the embedding of metal NPs onto flexible papers using reversal nanoimprint lithography. Second part describes the synthesis of near-infrared (NIR)-absorbing gold nanoframes (GNF), and a systematically comparative study of their physiological stability and biocompatibility with hollow Au-Ag nanoshells (GNS).

    Dr. Dehui Wan received his B.S. (2003) in Chemistry and Ph.D. (2010) in Material Science and Engineering at the National Taiwan University. He completed his doctoral thesis under the supervision of Dr. Hsuen-Li Chen and developed various novel nanoparticle-based optical systems for light-harvesting devices and optical data storage. He later worked with Dr. Younan Xia as a postdoctoral research fellow of Department of Biomedical Engineering, Georgia Institute of Technology. He joined the faculty of National Tsing Hua University as a tenure-track Assistant Professor in 2013 and was promoted to Associate Professor in 2017. His work integrates shape-controlled synthesis, surface chemistry and optical engineering of nanostructures to develop novel bio/chemical sensors, energy efficient devices, and photothermal cancer therapy. Dr. Wan has published 26 journal papers with nearly 1000 citations and an h-index of 15, and he also published 4 patents. He received National Tsing Hua University Young Investigator Award (2016) and Dr. Zhao-ren Li Biomedical Engineering Young Investigator Award (2016).
