摘要Gold nanocubes demonstrate unique optical properties of the high photoluminescence (PL) quantum yield and a remarkably enhanced extinction band at 544 nm. The 4 X 10(-2) PL yield, which is about 200 times higher than that of gold nanorods, allows gold nanocubes to be successfully used in cell imaging of human liver cancer cells (QGY) and human embryo kidney cells (293T) with a common method of single-photon excitation. The high extinction coefficients of gold nanocubes also facilitate them carrying out the photothermal therapy of QGY and 293T cells, showing similar photokilling efficiency as compared to gold nanorods.
