  • To determine optimal gold nanoshell structures for maximum absorption efficiency at specific near-infrared wavelengths.

Main Methods:

  • Utilizing light-scattering theory for coated spheres to model gold nanoshell optical properties.
  • Simulating absorption spectra by varying nanoparticle parameters and surrounding medium composition.

Main Results:

  • Absorption peak position and intensity are tunable by adjusting core material, medium, core radius, and shell thickness.
  • Hollow gold nanoshells demonstrated maximum absorption efficiency of 5.42 at 800 nm with a shell thickness of 4.8 nm and core radius of 38.9 nm.

Conclusions:

  • Gold nanoshells' optical properties can be precisely engineered for biomedical applications.
  • Optimized hollow gold nanoshells are highly effective photothermal conversion agents for use in medicine.
