COMPOSITE PARTICLE, METHOD FOR PRODUCING THE SAME, DISPERSION SOLUTION, MAGNETIC BIOSENSING APPARATUS AND MAGNETIC BIOSENSING METHOD |
摘要 |
<p>To provide a method for producing composite particles small in particle size, excellent in mono-dispersibility, high in magnetic-substance content per particle, large in saturation magnetization, excellent in dispersion stability and having non-specific adsorption suppressibility. The method includes (1) mixing a first liquid and particles to prepare a mixture solution;(2) mixing the mixture solution and a second liquid to prepare an emulsion containing a dispersoid formed of the first liquid and the particles; (3) mixing a polymer compound with the emulsion; and (4) fractionating the emulsion to extract the first liquid from the dispersoid to produce the composite particles each containing the particles and the polymer compound, characterized in that the dispersoid has a single-peak particle size distribution and a dispersity index (Dhw/Dhn) calculated from a number-average hydrodynamic particle size (Dhn) and a weight-average hydrodynamic particle size (Dhw) is 1.5 or less.</p> |
