  • Existing methods struggle to maintain the integrity of transported subcellular components.

Purpose of the Study:

  • To introduce a novel optical trap for single-cell nanosurgery with reduced photodamage.
  • To overcome the limitations of conventional optical tweezers in preserving organelle function.

Main Methods:

  • Utilized a polarization-shaped optical vortex trap.
  • Applied the trap for single-cell nanosurgical procedures.

Main Results:

  • The optical vortex trap demonstrated reduced photodamage compared to conventional optical tweezers.
