    Abstract

    Spherical gold nanoparticles with a plasmonic extinction peak at 532 nm and two sizes of star shaped gold nanoparticles with plasmonic extinction peaks at 532 nm and 600 nm were synthesised and introduced into tissue phantoms as exogenous absorbers. The photoacoustic signals generated from the three different nanoparticle morphologies embedded in tissue the phantoms is compared. The effect of nanoparticle concentration on the generated photoacoustic signal strength was also investigated for the spherical nanoparticles. At an excitation laser wavelength of 532 nm, the spherical gold nanoparticles were shown to produce the greatest photoacoustic response.
