Title:
BONDED MASS OF ACCUMULATED NANOPARTICLES AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2009/116551
Kind Code:
A1
Abstract:
A bonded structure of accumulated nanoparticles (nanocubes) of different kinds which have the same size is constructed. Two kinds of nanoparticles having different chemical compositions (BaTiO3 nanocubes (BT), SrTiO3 nanocubes (ST)) are separately produced. To organic solvent (hexane) solutions to which these two kinds of nanocubes (BT and ST) have been added respectively, a dispersant/crosslinking agent (trioctylphosphine oxide) capable of promoting the dispersion of the individual nanocubes and the adsorption thereof via the chemical binding to binders (DNA bases A and T) respectively corresponding thereto is added. Further, at least two kinds of binders showing excellent ability to selectively bind to the two kinds of nanocubes (BT and ST) are separately adsorbed via chemical bonds. Subsequently, these solutions of the two kinds of nanocubes are mixed together. Thus, the two kinds of nanocubes (BT and ST) are selectively drawn together followed by accumulation and binding by the binders.
