摘要

光学力用于定位和聚集不同应用的纳米颗粒。特别是，利用等离子体增强光力来引导被生物分子包围的金纳米棒，在液体缓冲环境中按需产生热点。这样可以在10 nM水平上进行蛋白质检测。此外，研究了液相剥离层状材料(hBN, MoS2, WS2)的光学力，并利用光学力推动和聚集纳米结构以特定的模式。

Optical Force Positioning and Aggregation of Nanoparticles

Optical forces are used to position and aggregate nanoparticles for different applications. In particular, plasmonic enhanced optical forces are exploited to direct gold nanorods surrounded by biomolecules to create hot-spots on demand in a liquid buffered environment. This enables protein detection at the 10 nM level. Furthermore, optical forces on liquid phase exfoliated layered materials (hBN, MoS2, WS2) are studied and used to push and aggregate nanostructures in specific patterns.
