a Components and structures of the CD44 and SR-B1 dual-targeting HA-HPPS nanoparticles. b Dual-modality fluorescence and photoacoustic imaging of HA-HPPS in SLNs, which includes near-infra-red (NIR) fluorescence imaging for long-term monitoring of the accumulation and retention of HA-HPPS in SLNs and photoacoustic microscopy (PAM) for intraoperative determination of the metastatic status of SLNs in breast cancer
