Abstract
A gold nanoparticle composition is provided that includes a spherical gold nanoparticle and an organic ligand molecule. The organic ligand molecule bonds to the gold nanoparticle. Thus, the gold nanoparticle composition has at least one absorption peak wavelength (plasmon absorption wavelength) within the region of 600-1000 nm. Consequently, the gold nanoparticle composition self-heats when irradiated with electromagnetic waves having a wavelength of 600-1000 nm.
