Abstract

We perform a set of experiments on photo-heating in
tissues containing gold nanoshells (NSs) and nanorods (NRs). The temperature
of tissues were measured with different amounts gold NSs and NRs under
illumination of a continuous diode laser at 808 nm and power density from 20
to 62 W/cm$^{2}$. The temperature of the tissues injected gold nanoparticles
increased to $66 \pm 4$^{\circ}$C for $2.1 \times 10^{8}$ NSs and $73\pm 4$
$^{\circ}$C for gold $5.4 \times 10^{9}$ NRs after 10 min exposition at power density
35 W/cm$^{2}$. The control tissue without gold nanoparticles demonstrated a
significantly lower temperature $40 \pm 4$ $^{\circ}$C in the same time of
illumination. The temperature can be reached up to around 100$^{\circ}$C for
tissue with both NSs and NRs at 62 W/cm$^{2}$ inrradiation for $7-10$ min.
