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.
