Particle Morphology and Rotation Impact Optical Manipulation

Optical manipulation, a technique using light to move and control objects at micro and nanoscale, is fundamental in fields such as biology and nanotechnology. However, the shape and orientation of particles can drastically alter their interaction with the optical field, complicating precise control. A new study has explored how the morphology and rotation of these particles influence the optical forces and torques exerted on them, providing a deeper understanding of these phenomena.
