POLYMER COMPOUND WATER-SOLUBILIZING NANOPARTICLE AND WATER-SOLUBILIZED NANOPARTICLE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a water-solubilized nanoparticle stable in water and to provide a biological-body tagging material consisting of the water-solubilized nanoparticle.;SOLUTION: An agent for hydrophilicizing treatment consisting of an unsaturated higher fatty acid and a copolymer with one or more kinds of a water soluble monomer is produced. If a nanoparticle is hydrophilized by coating the nanoparticle with the above agent, the nanoparticle can be solubilized in water and a solubilized liquid thus formed is stable and does not coagulate.;COPYRIGHT: (C)2006,JPO&NCIPI
