    摘要: Nano-sized inorganic particles having uniform particle sizes and precisely controlled particle diameters have already been produced by synthesis in an organic solvent, but these nano-sized inorganic particles are hindered from dispersing in a polar solvent because of the adsorption of a long-chain fatty acid on the surfaces of the particles. Further, it was difficult to form nano-sized inorganic particles dispersible in a polar solvent by replacing the long-chain fatty acid coats. According to the invention, various surface-coated inorganic particles dispersible in polar solvents can be produced from fatty acid-coated inorganic particles by adding a temporary coating substance such as thiomalic acid to a nonpolar solvent containing fatty acid-coated inorganic particles dispersed therein to replace the fatty acid coats by the temporary coating substance, dispersing the inorganic particles coated with the temporary coating substance in a polar solvent, and then adding a coating substance dispersible in a polar solvent, e.g., citric acid to the obtained dispersion to replace the temporary coating substance coats covering the inorganic particles by the coating substance dispersible in a polar solvent.

    摘要: An object of the present invention is to provide a novel biosensing method as the novel application development of the magnetic particles in the biosensing. In an affinity reaction of biosensing, ligands are immobilized to magnetic fine particles and the magnetic fine particles are forced to reaction fields of the affinity reaction by magnetic guiding so as to bring the affinity reaction, which is the velocity controlling factor in the sensing, to high rates. According to the present invention, coated magnetic fine particles with having both of the high dispersion performance and high magnetic responsibility as the above described magnetic fine particles and the affinity reaction occurs quickly and in high density such that the present invention makes it possible to obtain relatively large signals within significantly short time duration when compared to the conventional art.

    摘要: Polymer particles are provided which contain fluorescent molecules with high presence ratio in a polymer layer thereof and a method for preparing thereof. Polymer particles are swelled in a non-aqueous solution excluding exclusively water preferably promotes selling of the polymer layer and transfer of the fluorescent molecules to the polymer layer could not protected by water molecules such that much more fluorescent molecule may be introduced into inside of the polymer layer. Furthermore, since the water is added to the reaction system prior to evaporation removal of the non-aqueous solvent, dry-up of the polymer particles is prevented by the water remained in the reaction system and the polymer particles including fluorescent molecules with high presence ratio of the fluorescent molecules preferably keep high dispersibility using the above described procedures.
