Nanogold for Elastronics
主讲人先容：Wenlong Cheng is a professor and director of research in the Department of Chemical Engineering at Monash University, Australia. He is also an Ambassador Tech Fellow in Melbourne Centre for Nanofabrication. He earned his PhD from Chinese Academy of Sciences in 2005 and his BS from Jilin University, China in 1999. He held positions in the Max Planck Institute of Microstructure Physics and the Department of Biological and Environmental Engineering of Cornell University before joining the Monash University in 2010. His research interest lies at the Nano-Bio Interface, particularly plasmonic nanomaterials, DNA nanotechnology, nanoparticle anticancer theranostics and electronic skins. He has published >100 papers including 3 in Nature Nanotech, 1 in Nature Mater and 1 in Nature Comm. He is currently the editor for the Elsevier journal – Inorganic Chemistry Communications, and the editorial board members for a few journals including Cell press journal – iScience.
主要内容：Human is soft and curvilinear yet current electronics are rigid and planar. This is the fundamental gap towards bio-integrateable electronics, which is important for future wearable/implantable biodiagnostics and artificial intelligence. I have been working on gold nanomaterials for about 20 years, and recently striven to apply nanogold for soft plasmonics 1-5 and soft electronics (i.e. elastronics). In this talk, I will firstly give a brief overview of my group nanobionics research program 6-10, and then I will discuss how we apply ultrathin gold nanowires to the design of electronic skin materials for soft wearable sensors enabling the monitoring of biological signals in real-time in-situ in a wireless fashion as well as for soft energy devices (e.g. supercapacitors). Gold has been known for its superior biocompatibility, chemical inertness, facile wet chemical synthesis and band-gap matching with p-type semiconductor materials, hence, our nanogold-based strategy may lead to novel soft devices for next-generation wearable/implantable electronics for health monitoring anytime anywhere.
