Novel nanoprobe helps realize in vivo real-time detection of sentinel lymph node metastases in breast cancer

Sentinel lymph node (SLN) is the first lymph node draining from a tumor, and sentinel lymph node biopsy (SLNB) for breast cancer is the standard procedure for clinically node-negative (cN0) early-stage breast cancer. Currently, the commonly used tracers in clinical practice can only trace SLNs without evaluating their metastatic status.
