Enabling Prussian Blue with Tunable Localized Surface Plasmon Resonances: Simultaneously Enhanced Dual-Mode Imaging and Tumor Photothermal Therapy.

Prussian blue (PB) has been used as a photothermal conversion agent to generate heat to induce localized damage to tumor. However, its therapeutic efficiency is far from satisfactory. One of the major obstacles is that the maximum NIR absorption peak of PB within 690-720 nm cannot be optimized near the wavelength of the laser to enhance its therapeutic efficiency. Herein, we report that the integration of Gd
