Abstract | Provided is a sensitized magnetic responsive particle comprising: a magnetic responsive particle constituted of a core particle and at least one magnetic layer disposed on the core particle, the magnetic layer being composed of fine particles of a magnetic metal and/or an oxide of the same; and a substance that specifically acts on an object of interest, the substance being supported on the magnetic responsive particle. The coefficient of variation of the weight-average particle diameter of the magnetic responsive particles is no more than 15%. The magnetic responsive particle has excellent magnetic separability.
L'invention concerne une particule sensible magnétique sensibilisée comprenant : une particule sensible magnétique constituée d'une particule noyau et d'au moins une couche magnétique disposée sur la particule noyau, la couche magnétique étant composée de fines particules d'un métal magnétique et/ ou d'un oxyde de celui-ci ; et une substance qui agit spécifiquement sur un objet d'intérêt, la substance étant supportée sur la particule sensible magnétique. Le coefficient de variation du diamètre de particule moyen en poids des particules sensibles magnétiques n'est pas supérieur à 15 %. La particule sensible magnétique a une excellente séparabilité magnétique.
磁気応答性粒子であって、コア粒子と、コア粒子上に配置された、磁性を有する金属および/またはその酸化物の微粒子からなる、少なくとも一層以上の磁性層とを有する磁気応答性粒子と;磁気応答性粒子上に担持された目的物と特異的に作用する物質と;を備え、磁気応答性粒子の重量平均粒子径の変動係数が15%以下である、感作磁気応答性粒子。優れた磁気分離性をもつ磁気応答性粒子が提供される。 |
