US20060188932A1 Particle having magnetic material incorporated therein, process for producing the same, particle for immunoaasay and method of immunoassay 有权
包含磁性材料的颗粒，其制备方法，免疫球蛋白颗粒和免疫测定方法

Particle having magnetic material incorporated therein, process for producing the same, particle for immunoaasay and method of immunoassay
摘要：
It is an object of the present invention to provide magnetic substance-encapsulated particles which have uniform magnetism, high dispersion stability and a narrow particle size distribution, a method of producing the same, particles for immunoassay formed by using the magnetic substance-encapsulated particles and a method of immunoassay in which the magnetic substance-encapsulated particles or the particles for immunoassay are used. The present invention relates to a magnetic substance-encapsulated particle, which comprises an organic polymer material and a magnetic substance having an average particle size of 1 to 30 nm, the magnetic substance being contained within a particle in a state of being dispersed.
摘要（中）：
