Definitions

  • the magnetic nanoparticles made water-soluble may be utilized for magnetic resonance imaging (MRI).
  • MRI magnetic resonance imaging
  • step (c) the halogen of the compound represented by Chemical Formula 7 is substituted with the compound represented by Chemical Formula 5, thereby resulting in a non-toxic surfactant for dispersing nanoparticles in water.
  • step (c) may be repeated several times. It is because the substitution with the compound represented by Chemical Formula does not occur easily if the compound represented by Chemical Formula 4 has a long alkyl chain and thus is strongly nonpolar.

Abstract

Le tensioactif ci-décrit est capable de disperser de manière stable des nanoparticules dans l'eau. Plus spécifiquement, il est capable de disperser de manière stable diverses nanoparticules dans l'eau tout en conservant leurs propriétés physiques. Il peut être appliqué à diverses nanoparticules telles que des métaux, des oxydes de métaux, des boîtes quantiques, et ainsi de suite.
