Abstract: front page image
(EN)The present invention provides a fluorine-based-solvent-soluble magnetic nano-particle which includes a magnetic nano-crystal core and a ligand shell containing a fluorinated hydrocarbon-based or fluorinated carbon-based carboxylic acid represented by chemical formula CF3-(CF2)x-(CH2)y-COOH. In addition, the present invention provides a method for producing a fluorine-based-solvent-soluble magnetic nano-particle, the method comprising: a first step of producing a second magnetic nano-particle, which includes a magnetic nano-particle core and a ligand shell containing a fluorinated hydrocarbon-based or fluorinated carbon-based carboxylic acid represented by chemical formula CF3-(CF2)x-(CH2)y-COOH, by adding and reacting a fluorine-based solvent, containing a fluorinated hydrocarbon-based or fluorinated carbon-based carboxylic acid represented by chemical formula CF3-(CF2)x-(CH2)y-COOH, in a solution in which a first magnetic nano-particle coated with fatty acid is dispersed in an organic solvent; and a second step of collecting the second magnetic nano-particle that has moved to a fluorine-based solvent layer.
(FR)La présente invention concerne une nanoparticule magnétique soluble dans un solvant à base de fluor qui inclut un noyau magnétique nanocristallin et une coque de ligand contenant un acide carboxylique à base d’hydrocarbure fluoré ou à base de carbone fluoré représenté par la formule chimique CF3-(CF2)x-(CH2)y-COOH. De plus, la présente invention concerne un procédé de production d’une nanoparticule magnétique soluble dans un solvant à base de fluor, le procédé consistant : en une première étape de production d’une deuxième nanoparticule magnétique, qui inclut un noyau de nanoparticule magnétique et une coque de ligand contenant un acide carboxylique à base d’hydrocarbure fluoré ou à base de carbone fluoré représenté par la formule chimique CF3-(CF2)x-(CH2)y-COOH, en ajoutant et en faisant réagir un solvant à base de fluor, contenant un acide carboxylique à base d’hydrocarbure fluoré ou à base de carbone fluoré représenté par la formule chimique CF3-(CF2)x-(CH2)y-COOH, dans une solution dans laquelle une première nanoparticule magnétique recouverte d’acide gras est dispersée dans un solvant organique ; et une deuxième étape de collecte de la deuxième nanoparticule magnétique qui a migré vers une couche de solvant à base de fluor.
