cRGD-Functionalized Calcium Carbonate Nanoprobe for Enhanced NIR-II Fluorescence Imaging and Tumor-Targeted Navigation.
Indocyanine green (ICG) holds promise for near-infrared-II (NIR-II) fluorescence imaging but is hindered by poor photostability, rapid clearance, and lack of targeting specificity. To address these challenges, we engineered a tumor-targeted nanoprobe (cRGD@ICN) by encapsulating ICG within a calcium carbonate (CaCO3) co...
