発明の名称 （英語） Three-dimensional structure of functional material 新技術説明会
発明の概要（英語） (US8796417)
It is to provide an inorganic thin film of titanium dioxide or the like which is controlled at the nanoscale and a three-dimensional structure of a functional material such as semiconductor nanoparticles.
A three-dimensional structure of an inorganic material is manufactured by introducing onto a surface of an inorganic substrate ferritin presenting on its surface a plurality of inorganic material-binding peptides; binding the ferritin in a monolayer onto the inorganic substrate; introducing an inorganic material onto the ferritin which is bound in a monolayer, while the inorganic material-binding peptides is having a binding and/or biomineralization ability for the inorganic material; forming a biomineral layer utilizing the biomineralization ability of the inorganic material-binding peptides; and subsequently repeating one or more times the steps (a) and (b) of a multilayering operation: (a) introducing onto the biomineral layer thus formed the ferritin having a binding ability to the biomineral layer, and binding the ferritin in a monolayer onto the biomineral layer; (b) introducing the inorganic material onto the surface of the ferritin which is bound in a monolayer, and forming a biomineral layer.
特許請求の範囲（英語） [claim1]
1. A multilayered three-dimensional structure comprising in the order of: (a) an inorganic substrate,
(b) an aggregate comprising and presenting on its surface a plurality of inorganic material-binding peptides consisting of the amino acid sequence shown in SEQ ID NO: 1, said aggregate of peptides (b) bound as a monolayer onto said inorganic substrate (a), and
(c) a biomineral layer formed from a substrate for a biomineralization reaction or a precursor for a biomineralization reaction by a biomineralization ability of the inorganic material-binding peptides, on the side of said aggregate of peptides (b), which is not bound to said inorganic substrate (a),
wherein the inorganic substrate (a) comprises at least one selected from the group consisting of titanium, silicon, silver, and gold, and
wherein the biomineral layer (c) is formed from at least one selected from the group consisting of silicon, silver, titanium, silicon oxides, silver oxides, and titanium oxides.
[claim2]
2. The multilayered three-dimensional structure according to claim 1, further comprising in the order of: (d) a further aggregate comprising and presenting on its surface a further plurality of inorganic material-binding peptides consisting of the amino acid sequence shown in SEQ ID NO: 1 and supporting an inorganic nanoparticle, said further aggregate of peptides (d) bound to the biomineral layer (c) on the side not bound to said aggregate of peptides (b), and
(e) a further biomineral layer formed on the unbound side of (d) from a substrate for a biomineralization reaction or a precursor for a biomineralization reaction by a biomineralization ability of the further inorganic material-binding peptides supporting the bound inorganic nanoparticle; and
optionally further comprising additional further layers of aggregate of peptides, supporting bound inorganic nanoparticle, and biomineral layer, in the order thereof,
wherein the biomineral layer (e) is formed from at least one selected from the group consisting of silicon, silver, titanium, silicon oxides, silver oxides, and titanium oxides.
[claim3]
3. The multilayered three-dimensional structure according to claim 1, further comprising in the order of: (f) a further aggregate comprising and presenting on its surface a further plurality of inorganic material-binding peptides consisting of the amino acid sequence shown in SEQ ID NO: 1, said further aggregate of peptides (f) bound to the biomineral layer (c) on the side not bound to said aggregate of peptides (b), and
(g) a further biomineral layer formed on the unbound side of (f) from a substrate for a biomineralization reaction or a precursor for a biomineralization reaction by a biomineralization ability of the further inorganic material-binding peptides; and
optionally further comprising additional further layers of aggregate of peptides and biomineral layer, in the order thereof,
wherein the biomineral layer (g) is formed from at least one selected from the group consisting of silicon, silver, titanium, silicon oxides, silver oxides, and titanium oxides.
