Main Results:

  • Optimizing plasmon resonance improves trapping force by two orders of magnitude.
  • A total enhancement of four orders of magnitude in trapping force is predicted compared to no nanostructures.

Conclusions:

  • Plasmonic nanostructures provide a powerful platform for enhanced nanoparticle trapping.
  • The proposed optimization strategy offers significant improvements in trapping efficiency.
  • Tunable optical properties of nanorods enable precise control over trapping applications.
