A method which can control crystallization of a biopolymer such as protein is provided. A silicon crystal (15) whose valence electrons are controlled to be capable of controlling the concentration of holes or electrons of the surface part in response to the environment of a buffer solution (14) containing the biopolymer such as protein is brought into contact with the solution (14), for getting a crystal of the biopolymer deposited on the surface of the silicon crystal (15). Crystallization is controlled by an electrical state which is generated by the controlled valence electrons on the surface of the silicon crystal (15).
Procédé de régulation de la cristallisation de biopolymères tels que des protéines, qui consiste à mettre un cristal de silicium (15) en contact avec une solution tampon (14) contenant un biopolymère, les électrons de valence du cristal étant régulés de sorte que la concentrations de trous ou d'électrons dans les molécules de surface puisse être régulée en fonction de l'environnement de la solution (14), et à déposer les cristaux de biopolymère sur la surface du cristal de silicium (15), la cristallisation du biopolymère étant régulée simultanément par l'état électrique induit à la surface du cristal (15) par les électrons de valence régulés.
