Title: NanoGold: Nanogold: From Chemical Synthesis to Soft Plasmonics and Disruptive Wearable Electronics

Abstract: 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”¹. I will focus on discussion how nanogold can be used to design soft plasmonic nanoassemblies² and electronic skins3 for applications in wearable bioelectronics, remote diagnostics, healthcare and energy devices^4-6.
