Photothermal effect of gold nanoshells in tissua

Abstract

This work presents the research results on photothermal effect caused by gold nanoshells SiO₂/AU and Fe₂O_3/SiO₂/Au in tissue under illmnination of a diode laser continuous light at 808 nm. The results shown that the average temperature of samples injected with 1x10⁸ SiO₂/AU and Fe₂O_3/SiO₂/Au nanoshells reach to 58° ± 5°C and 50° ± 5°C, respectively. The photothermal transduction efficiency of Fe₂O_3/SiO₂/Au and SiO₂/AU shells was determined as 16 % and 22 %, respectively. This study proves that gold nanoshells can be used to desừoy die tumor cells by photothermal effect.
