Title:
HYDROPHILIC METAL OXIDE NANOPARTICLE HAVING UNIFORM PARTICLE SIZE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2006104051
Kind Code:
A
Abstract:
To provide a hydrophilic iron oxide nanoparticle having a uniform particle size by synthesizing paramagnetic iron oxide powder having a spherical particle of ≤20 nm having in an organic solvent thereby securing the uniformity of the particle, and converting the particle into the hydrophilic one by chemical surface modification.
The metal oxide nanoparticle contains: a nanoparticle composed of a metal oxide core and a shell composed of the element same as the metal component in the core and formed on the surface of the core; and an organic matter containing an element to be covalently bonded with the metal element in the shell and a hydrophilic functional group-containing organic substance.
