Abstract
In recent years, the hyperthernaia using photothermal effect of gold nanorods (GNRs) has been highly attracted. In this research, we measured the temperature change in a GNRs suspension irradiated by a NIR laser beam based on laser-induced fluorescence, which was non-contact temperature measurement method. The temperature measurement of liquid in microscale domain can provide us an evaluation of the photothermal characteristics of GNRs and an estimation of GNRs concentration necessary to kill cancer cells. Experimental results clearly show that it is possible to evaluate photothermal behavior of GNRs solution under the light irradiation.
