Abstract

Particules composites magnétiques d’une taille moyenne de 0.01 to 4 mm comprenant des particules magnétiques et, superimposées sur les surfaces, des couches de chitosane. On fournit en particulier des particules composites magnétiques de structure à virole de cœur comprenant des particules magnétiques comme cœurs et des couches de chitosane comme virole, dont les particules magnétiques sont capables d’immobiliser des substances physiologiquement actives à haut rendement et après l’immobilisation, montrent une haute collectibilité par magnétisme. En outre, on fournit un procédé de production de particule composite magnétique composée de particules magnétiques et, surimposées sur les surfaces, des couches de chitosane, dont le procédé comprend les étapes de (a) dissolution du chitosane dans l’eau par acidification ; (b) dispersion des particules magnétiques dans la solution de chitosane et (c) lente neutralisation de la dispersion avec une base alkali faible.
