Abstract:
A method of growing a crystal of a macromolecule contained in a solution, comprising:a step of providing a solid-state component, whose valence electrons are controlled so that the concentration of holes or electrons in the surface part can be controlled in response to the environment of a solution containing said macromolecule, and which has at least two grooves or holes whose depths and/or widths of the opening parts differ from each other; anda step of bringing said solid-state component into contact with the solution containing said macromolecule to cover said at least two grooves or holes with said solution, whereinsaid valence electrons in said solid-state component are differently controlled between the inside and the outside of each of said grooves or holes so that crystallization of said macromolecule is facilitated inside rather than outside said grooves or holes, anda crystal of said macromolecule is grown in at least one of said grooves or holes holding said solution under an electrical state brought to the surface of said solid-state component by said controlled valence electrons.
