Photothermal transduction

NCs could be employed for in vivo applications. The UV-Vis absorption of the Cu2-xSe NCs showed a broad absorption peak at 970 mn which was attributed to the surface plasmon resonance. When these NCs were irradiated with a 800 nm laser for 5 min, they exhibited a photothermal transduction efficiency of 22% which is equivalent to Au nanorods (21%) and relatively higher than Au nanoshells (13%). Cu2.xSe NCs were effective in the destruction of cancer cells, and hence are promising candidate for photo-thermal applications.
