A phosphomolybdenum blue nano-photothermal agent with dual peak absorption and biodegradable properties based on ssDNA in near-infrared photothermal therapy for breast cancer

Phosphomolybdenum blue (PMB) was synthesized based on the interaction between ammonium molybdate and ssDNA phosphate ions using a one-pot hydrothermal method. PMB has excellent photothermal therapeutic effects on cancers in the NIR-II region.
