Multi‐Branched Plasmonic Gold Nanoechinus‐Based Triple Modal Bioimaging: An Efficient NIR‐to‐NIR Up and Down‐Conversion Emission and Photoacoustic Imaging

It is demonstrated for the first time that plasmonic gold nanoechinus can act as a triple modal bio imaging agent such as upconversion luminescence, NIR fluorescence, and photoacoustic contrast agent upon various NIR excitation sources.
