Paper Abstract
Gold nanoshells are a novel class of hybrid metal nanoparticles whose unique optical properties have spawned new
applications including more sensitive molecular assays and cancer therapy. We report a new photo-physical property of
nanoshells (NS) whereby these particles glow brightly when excited by near-infrared light. Specifically, we demonstrate
NS excited at 780 nm produce strong two-photon induced photoluminescence (TPIP). We characterized the
luminescence brightness of NS, comparing to that of fluorescein-labeled fluorescent beads (FB). We find that NS are 140
times brighter than FB. To demonstrate the potential application of this bright TPIP signal for biological imaging, we
imaged the 3D distribution of gold nanoshells targeted to murine tumors.
