Preparation of Ag₂Te Quantum Dots for Near-Infrared Fluorescence and Computed Tomography Imaging

The combination of second near-infrared window (NIR-II) fluorescence imaging and high-resolution computed tomography (CT) provides complementary information for the diagnosis, progression, and prognosis of clinical conditions. Ag₂Te quantum dots (QDs) are promising CT/NIR-II fluorescence dual-modal imaging probes due to their high atomic number and excellent fluorescence performance. Herein, we describe the synthesis, characterization, and evaluation of the biocompatibility of Ag₂Te QDs in vitro and in vivo for CT/NIR-II fluorescence dual-modal imaging.
