摘要：
Functionalized magnetic core-shell particles which are present predominantly in the form of isolated, essentially spherical individual particles, the core of which consists essentially of one or more magnetic iron oxides, the shell of which consists essentially of impervious, amorphous silicon dioxide, and the functionalization of which consists of amino or epoxy group units on the surface of the particles, and which additionally have a mean particle diameter d50 such that 2
