Imaging of distant tumor metastasis. (A) (i) NIR‐II imaging of human ovarian adenocarcinoma peritoneal metastases using DCNPs‐L₁‐FSH_β nanoprobe. (ii) Imaging was obtained at 22 h; (iii) the enlargement of the NIR‐II nanoprobes with large peritoneal metastatic tumors (nos. 1–8) and ultra‐small lesions (nos. 9–3). 1000 nm LP filter; Scale bar, 1 cm.
