cRGD-Functionalized Calcium Carbonate Nanoprobe for Enhanced NIR-II Fluorescence Imaging and Tumor-Targeted Navigation.
A tumor-targeted nanoprobe is engineered by encapsulating ICG within a calcium carbonate core, followed by surface functionalization with phospholipids and cyclic RGD (cRGD) peptides, which exhibited remarkable tumor-targeting ability across other tumor models (U87, 4T1).
