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/cm2. The temperature of the tissues injected gold nanoparticles increased to $66 \pm 4∘C for 2.1×108 NSs and 73± 4∘C for gold 5.4×109 NRs after 10 min exposition at power density 35 W/cm2. The control tissue without gold nanoparticles demonstrated a significantly lower temperature 40± 4∘C in the same time of illumination. The temperature can be reached up to around 100∘C for tissue with both NSs and NRs at 62 W/cm2 inrradiation for 7−10 min
