  • Particle and photoacoustic contrast agent having the particle
    Patent number: 9352053
    Abstract: An iron oxide particle constituting a Resovist (trademark) absorbs a small quantity of light in a near infrared region and emits a weak photoacoustic signal. According to a particle having a catechol-like compound and iron atoms, the particle having a ratio of the number of moles of the catechol-like compound to the number of moles of the iron atoms of 270/10,000 or more, light absorption in the near infrared region increases and a strong photoacoustic signal can be transmitted.
