Area of Science:

  • Optics
  • Nanotechnology
  • Physical Sciences

Background:

  • Optical forces enable microparticle manipulation across various scientific fields.
  • Extending optical trapping to the nanoscale requires advanced techniques and materials.

Purpose of the Study:

  • To demonstrate and analyze the trapping of single nanoparticles within plasmonic coaxial nano-apertures.
  • To investigate the influence of nano-aperture design on trapping efficiency and force.

Main Methods:

  • Fabrication and experimental testing of plasmonic coaxial nano-apertures with varying inner disk sizes.
  • Theoretical simulations to estimate optical forces and interpret trapping mechanisms.
  • Characterization of trapping performance using 20 nm polystyrene particles at 980 nm wavelength.

Main Results:

  • Achieved a high normalized experimental trap stiffness of 3.50 fN nm⁻¹ mW⁻¹ μm⁻² for an optimal nanodisk diameter of 149 nm.
  • Demonstrated rapid particle trapping (< 8 s) at high concentrations (14 × 10¹¹ particles ml⁻¹) and low laser intensity (0.59 mW μm⁻²).
  • Observed trapping enhancement attributed to combined effects of enhanced electromagnetic near-field and localized temperature increase.

Conclusions:

  • Plasmonic coaxial nano-apertures effectively enable nanoscale optical trapping of nanoparticles.
  • The optimized design offers high trapping accuracy and fast delivery, bridging optical manipulation and nanofluidics.
  • This technology holds significant potential for applications in nanoparticle delivery and precise manipulation.
