报告人简介:

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.

报告摘要:

Gold is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history. The world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry. Nanogold represents the earliest record of human nanotechnology, which wasn’t understood until about a century ago. With the birth of nanoscience and nanotechnology, gold chemistry flourishes significantly. This enables shaping gold at the nanoscale with well-defined size and shape, forming so-called “artificial periodic table”. I will briefly go through a few examples in my nanobionics lab how “artificial gold elements” can be used to design chemical sensors, biosensors, flat lens, anti-counterfeit, wearable sensors, stretchable energy devices, and targeted cancer theranostics.
