Chemical Physics Seminar: Optically & Acoustically Directed Material Assembly

Abstract:

We present a novel concept based on the idea that mechanical forces arising from optical traps and standing acoustic waves can be used to influence the products of ongoing chemical reactions. These forces dictate the spatial distribution of the materials, their mesoscopic structure and could allow the formation of new hybrid materials. This has many benefits compared to other "bottom-up" methods for material assembly that conventionally rely on accumulation of preformed materials.

A key feature of this approach is its modularity, as it could be implemented on various material systems. Due to the flexibility in material choice, this innovative approach will open the door to new ways to act upon materials, with envisioned applications for electronics, photonics and drug delivery systems.
