Monomeric or Homodimer Conjugates of Fibroblast Activation Protein Inhibitor and Cyanine 7 Bearing a Meso-Chloride as Near-Infrared Fluorescence Probes: Design, Synthesis, and Comparative In Vivo Imaging of Distinct Breast Cancer Subtypes

Intraoperative fluorescence navigation can illuminate the tumor, directing surgeons to accurately achieve negative margins, which not only reduces recurrence but also minimizes the incidence of complications. Herein, we developed two near-infrared fluorescent probes
