(A) UV/vis emission spectra of [64Cu]CuCl2 in PBS containing various concentrations of Qtracker705 nanoparticles (Qdots ) demonstrate Cerenkov radiation energy transfer (CRET); (blue) [64Cu]CuCl2 without Qdots, (green) [64Cu]CuCl2 with 49 nM Qdots, (orange) [64Cu]CuCl2 with 222 nM Qdots, (red) [64Cu]CuCl2 with 400 nM Qdots, (black) non-radioactive CuCl2 without Qdots, (brown) non-radioactive CuCl2 with 400 nM Qdots, (gray) decayed [64Cu]CuCl2 with 400 nM Qdots. (B) Fluorescence emission spectrum (350 nm excitation) of decayed (>8 half-lives) [64Cu]CuCl2 in PBS containing 400 nM Qtracker705. (C) UV/vis emission spectra of [99mTc]NaTcO4 in PBS without (black) and with (red) 400 nM Qtracker705 nanoparticles.
