Article Synopsis
- Femtosecond (fs) laser trapping produces unique behaviors in silica, modified silica, and polystyrene nanoparticles in water, revealing distinct optical dynamics when compared to continuous wave (CW) laser trapping.
- Silica nanoparticles are tightly held and can be ejected in an assembly at higher laser powers, while hydrophobically modified silica and polystyrene nanoparticles are expelled in sequences that create bubbles, with ejection occurring perpendicular to the laser's polarization.
- The study also maps the changing optical forces affecting a single polystyrene nanoparticle, highlighting how these forces lead to assembly, ejection, and bubbling, which suggests potential applications for new material fabrication methods.
