摘要
In article number 1600107, Kuo Chu Hwang and co‐workers present multi‐branched plasmonic gold nanoechinus exhibiting excellent in vitro and in vivo triple modal bioimaging properties, including upconversion luminescence imaging upon 980 nm CW laser excitation at exceptionally low light intensities (2–100 mW cm−2), NIR fluorescence imaging in the biological window II, and photoacoustic imaging with 10 fold higher amplitude than gold nanorods in a CT‐26 solid tumor model.
