Trifolium-like Platinum Nanoparticle-Mediated Photothermal Therapy Inhibits Tumor Growth and Osteolysis in a Bone Metastasis Model

Bone metastasis is a frequent and fatal complication of cancer that lacks effective clinical treatment. Photothermal therapy represents a new strategy for the destruction of multiple cancers. In this study, trifolium-like platinum nanoparticles (TPNs) with small size and excellent photothermal conversion property are prepared via a facile and green method. TPNs show minimal cytotoxicity on normal cell lines and kill cancer cells upon exposure to a near-infrared light. These nanoparticles effectively inhibit tumor growth and prevent osteolysis in a bone metastasis model. This study offers a promising strategy in the treatment of bone metastasis. Photothermal ablation of bone metastasis: Trifolium-like platinum nanoparticle-mediated photothermal therapy efficiently suppress tumor growth and osteolysis in a bone metastasis model. offers a promising strategy in the treatment of bone metastasis.
