Dyed inorganic composite particles and process for production thereof |
摘要 |
Dyed inorganic composite particles having a mean particle diameter of 0.1 to 10.0 micrometers and a particle dispersibility value of at least 80%, each of said particles consisting of at least three layers comprising a core, a dyed layer on the surface of the core and a coated layer on the dyed layer, the core being composed of an inorganic compound, the dyed layer being composed of a dye or a mixture of a dye and an inorganic compound, and the coated layer being water-insoluble and light-pervious and composed of an inorganic compound or a mixture of it with a dye. The particles are useful as a carrier for preparing an immunological diagonostic reagent by binding an immunologically active substance (an antigen and an antibody) to them, particularly an immunological diagnostic reagent for use in a microtiter method, or as a hydrophilic pigment.
