Bifunctional Tumor-Targeted Bioprobe for Phothotheranosis

Biomaterials Research, Год журнала: 2024, Номер 28

Background: Near-infrared (NIR) phototheranostics provide promising noninvasive imaging and treatment for head neck squamous cell carcinoma (HNSCC), capitalizing on its adjacency to skin or mucosal surfaces. Activated by laser irradiation, targeted NIR fluorophores can selectively eradicate cancer cells, harnessing the power of synergistic photodynamic therapy photothermal therapy. However, there is a paucity bioprobes showing tumor-specific targeting effective phototheranosis without hurting surrounding healthy tissues. Methods: We engineered bifunctional bioprobe designed precisely target HNSCC induce using bioconjugation cyclic arginine-glycine-aspartic acid (cRGD) motif zwitterionic polymethine fluorophore. The cytotoxic effects cRGD-ZW800-PEG were measured assessing heat reactive oxygen species (ROS) generation upon an 808-nm irradiation. then determined in vivo efficacy FaDu xenograft mouse model HNSCC, as well biodistribution clearance, customized portable system. Results: Real-time revealed that intravenously administered tumors rapidly within 4 h postintravenous injection tumor-bearing mice. Upon produced ROS simultaneously exhibited tumoral tissue affecting neighboring Importantly, all unbound cleared through renal excretion. Conclusions: By combination with tailored tumor selectivity, our ushers paradigm treatment. It promises safer more efficacious therapeutic avenues against cancer, marking substantial advancement field.
