Gold nanoparticle trapping and delivery for therapeutic applications

Figures & data

Figure 1 Basic principles of optical tweezers.

Note: A particle is trapped in the potential well formed by dark solitons at the center wavelength, λ₀.

Figure 2 PANDA ring resonator.

Figure 3 Results of dynamic optical tweezers generated at four different center wavelengths, where E₁, E₂, E₃, and E₄ are circulated in optical fields within the center ring resonator shown in (A), (B), (C), and (D), respectively. E_t and E_d are output optical fields generated at the throughput and drop ports of the PANDA ring as shown in (E) and (F), respectively.

Figure 4 Results of the optical trapping tool with different wavelength.

Notes: Add-drop filter radius = 10 μm; right-hand ring radius and left-hand ring radius = 4 μm.

Figure 5 Proposed system for trapping and transporting gold nanoparticles to the required target. A shows trapping part, B shows transporting part.

Abbreviations: RL, left-hand ring resonator; RR, right-hand ring resonator; R, add-drop filter.
