3-Carboxyphenylboronic acid is a biochemical reagent with multiple functions including nanoparticle enhancement, perovskite passivation, fluorescence quenching, and adhesion. 3-Carboxyphenylboronic acid improves tumor penetration and pulmonary retention of nanoparticles, and serves as a tumor-targeting ligand for carboxymethyl chitosan nanoparticles. 3-Carboxyphenylboronic acid optimizes film crystallization via coordinate chelation of free lead/iodide ions in perovskites. 3-Carboxyphenylboronic acid acts as an additive for n-i-p perovskite solar cells. Conjugation of 3-Carboxyphenylboronic acid with PPEG8 quenches the near-infrared fluorescence of single-walled carbon nanotubes, enabling aqueous dispersion of carbon nanotubes through binding to the diol structure of saccharides .

Zopocianine (OTL-0078; OTL78) is a near-infrared optical probe targeting PSMA. Zopocianine binds to PSMA on the surface of PSMA-expressing cells, enters cells via receptor-mediated endocytosis, and accumulates in acidic endosomes. Zopocianine selectively accumulates in PSMA-positive cancer tissues and enables the detection of small tumors, primary prostate tumors, and locoregional metastases. Zopocianine helps achieve negative tumor surgical margins during fluorescence-guided surgery. Zopocianine is applicable to research related to prostate cancer .

IR-1048 is a nitroreductase (NTR)-responsive near-infrared fluorescence (NIR)/photoacoustic (PA) imaging probe and photothermal agent. IR-1048 is coupled with a nitroimidazole group to form IR-1048-MZ. IR-1048-MZ is catalytically reduced by NTR in a hypoxic environment, restoring strong near-infrared absorption and fluorescence emission (NIR II window), while activating the photothermal effect. IR-1048 relies on NTR-mediated electron transfer to relieve intramolecular fluorescence quenching, achieving specific imaging and photothermal ablation of tumor hypoxic areas. IR-1048 is mainly used for high-contrast NIR II/photoacoustic imaging and photothermal therapy research and tumor diagnosis of the tumor hypoxic microenvironment .
