  • Patent number: 11291726
    Abstract: The present invention relates to near-infrared-absorbing dye-based composite particles which exhibit a photothermal effect and/or photoacoustic signal upon photoirradiation, a preparation method thereof, and a use thereof. The near-infrared-absorbing composite particles comprise: a water-insoluble salt of a near-infrared-absorbing dye, which comprises anions of the near-infrared-absorbing dye and metal cations capable of forming a precipitation product with the anions of the near-infrared-absorbing dye; and particles of a polymeric surfactant, in which a water-insoluble salt of the near-infrared-absorbing dye is supported in the hydrophobic part of the polymeric surfactant.
